aloe, (genus Aloe), genus of more than 500 species of shrubby succulent plants in the family Asphodelaceae native to Africa, Madagascar, and the Arabian Peninsula. Several species are cultivated as ornamentals and houseplants and for their medicinal leaves. Physical description soap aloeSoap, or zebra, aloe (Aloe maculata, formerly Aloe saponaria).(more)aloeAloe plants (genus Aloe) in the Transkei region of South Africa.(more)Most members of the genus have a rosette of leaves borne either at ground level or at the end of a stem. The leaves are usually succulent and fleshy and commonly have sharp toothed edges. Certain aloe species retain dense dead leaves around their stems to serve as insulation against the heat of wildfires. The tubular flowers range in colour from white to yellow to red. Many species are pollinated by non-hovering birds, such as sunbirds, and the flower clusters of such species are supported by tall sturdy stalks upon which the birds can land. The seeds are produced in dry capsules.

Plants: From Cute to Carnivorous
Major species and uses Several species are cultivated as ornamentals for their attractive architectural leaves and colourful flowers. Spiral aloe (Aloe polyphylla) is a popular specimen for its compact geometric spiral of spiny leaves. Arabian aloe (A. rubroviolacea) has long blue-green leaves with red teeth and is planted outdoors in warm climates; the leaves turn red if exposed to full sun. Snake, or mountain, aloe (A. broomii) is a common potted plant grown for its dense rosette of triangular leaves with dark teeth.
aloeGelatinous interior of the leaves of aloe (Aloe vera), a succulent plant.(more)The juice of some species, especially the popular potted plant known as true aloe (Aloe vera), is used as an ingredient in cosmetics and in medicine as a purgative and as a treatment for burns. The gelatinous interior of the leaves is commonly applied directly to the skin as a beauty treatment or to soothe sunburns. Melissa Petruzzello

How to Use Aloe Vera
Aloe vera is a cactus-like plant used for centuries as medicine to treat sunburn, rashes, burns, wounds, and other skin conditions. In addition to external uses, aloe vera is thought by some to treat constipation, heartburn, and hyperglycemia (high blood sugar) when taken internally.
Aloe vera is widely available as a distilled juice, dietary supplement, and ingredient in face creams, body lotions, and skin ointments. Although the stems of the aloe plant and the gooey gel inside can be eaten raw or cooked, they may be unsafe if consumed in excess.
This article takes a look at the health benefits of aloe vera as well as possible side effects, risks, and interactions of this popular herbal remedy.

Medical Uses of Aloe Vera
The aloe vera plant has long, thick triangular leaves and is relatively easy to grow. The thick outer layer consists of the rind, and the middle layer consists of a bitter, yellow sap. At the center is a gel that can be applied directly to the skin.
In traditional and folk medicines, aloe vera has been used internally and externally to treat a wide range of unrelated medical conditions. Today, there are aloe vera supplements, juices, and skin or hair care products that are thought to have therapeutic effects.
Here is what some of the current research says about the possible health benefits of aloe vera:
Wound Healing
Aloe vera gel applied to the skin is thought to promote wound healing, including injuries like:
SunburnThermal burnsFrostbiteSurgical woundsSkin ulcersMouth ulcersBedsores
A 2019 review of studies concluded that aloe vera was more effective than petroleum jelly, framycetin antibiotic cream, and silver sulfadiazine 1% ointment in healing a wide variety of wounds, including burns, surgical wounds, and pressure sores. It also appeared to reduce pain while healing, in part by keeping scar tissues well-hydrated and flexible.
Laboratory studies suggest that aloe vera promotes healing by accelerating new skin cell growth. The gel also has potent anti-inflammatory properties that may reduce swelling and redness.
Even so, there is not enough evidence to recommend aloe vera as an effective treatment for psoriasis or eczema. There is also no evidence that aloe vera can speed the healing of cold sores or genital herpes caused by the herpes simplex virus (HSV).
Skin Health and Aging
While some people promote aloe vera as anti-aging, there is little evidence that aloe vera in any form can reverse the signs of aging on a cellular level. However, it does have definite benefits for the overall health of aging skin.
In addition to increased skin cell turnover and moisture retention, aloe vera gel contains antioxidants and UV-protective compounds that may prevent long-term skin damage and photoaging. Some studies even report that the daily application of aloe vera can significantly reduce visible wrinkles and discoloration.
Tooth and Gum Disease
When applied to the teeth and gums, aloe vera may reduce dental plaque buildup and, in turn, reduce the risk of cavities and gum disease.
A 2015 study in Contemporary Clinical Dentistry found that aloe vera's antibacterial effects reduce bacteria that promote plaque growth and the development of cavities. When used as a mouthwash with daily brushing, aloe vera was also shown to prevent gingivitis and periodontal (gum) disease.
Acid Reflux and Heartburn
Aloe vera, when taken internally, is thought to reduce acid reflux and heartburn by slowing the production of stomach acids. Animal studies suggest that compounds in aloe vera may alter the gut-brain axis (GBA) which regulates digestion, including the production of acids.
A small pilot study investigated the hypothesis in people with gastroesophageal reflux disease (GERD). The researchers found that aloe vera syrup reduced acid reflux symptoms as well as the drug Prilosec (omeprazole) commonly used to treat GERD.
Constipation
Aloe vera has a strong laxative effect that may be useful in the treatment of occasional constipation. It appears to act similarly to stimulant laxatives like Dulcolax (bisacodyl) that increase gut motility (intestinal contractions that move food through the gut).
In studies, aloe vera was shown to be beneficial for people with not only constipation-predominant irritable bowel syndrome (IBS-C) but also diarrhea-predominant irritable bowel syndrome (IBS-D). It is thought to do so inhibiting the growth of harmful bacteria in the gut that promotes diarrhea.
Potential Risks
In 2002, the U.S. Food and Drug Administration (FDA) banned laxative manufacturers from including aloe vera in over-the-counter products due to the lack of safety research.
Diabetes and High Cholesterol
There remains debate as to whether aloe vera can reduce blood glucose (sugar) in a way that is beneficial to people with type 2 diabetes. Proponents suggest that it can do so by improving insulin sensitivity (in which cells are better able to absorb glucose in the blood).
A 2021 review of studies involving 1,315 participants concluded there was "moderate" evidence that aloe vera could help lower blood sugar in people with type 2 diabetes. On the other hand, the evidence was "moderate to high" that it could prevent disease progression in people with prediabetes.
Several studies involving people with diabetes have shown that aloe vera doesn't only reduce blood sugar but can also decrease triglycerides and "bad" low-density lipoprotein (LDL) cholesterol that contribute to heart disease.
Side Effects of Aloe Vera
Side effects of aloe vera applied to the skin are uncommon. Even in oral forms, the plant is generally well tolerated. This is especially true of topical and oral aloe preparations in which latex has been removed.
Common Side Effects
Skin irritation is possible, though uncommon when aloe vera is applied topically. With that said, aloe vera may cause rash and hives in people who are allergic to other plants in the lily family, such as onions, garlic, and tulips.
Common side effects of oral aloe vera include:
Nausea
Diarrhea
Stomach cramps
Vomiting
Severe Side Effects
The risk of side effects can vary by the formulation. Aloe vera gel and juice appear to cause fewer reactions than whole-leaf aloe vera extract and aloe latex found in certain oral supplements. Problems generally occur when aloe vera is overused.
When taken at higher doses, aloe vera may cause:
Drug-induced hepatitis: The risk varies, but liver toxicity generally occurs with the prolonged use of aloe vera supplements over months or years.
Acute kidney failure: Kidney injury may occur with the prolonged use of aloe vera latex in doses greater than 1 gram per day. Some cases of aloe vera-induced kidney failure have been fatal.
Aloe Vera and Cancer Risk
Whole-leaf aloe vera extract has been shown to be carcinogenic in rats and is currently classified by the International Agency for Research on Cancer as a possible human carcinogen (Group 2B). Some human studies suggest that the product may increase the risk of colorectal cancer, but more research is needed.
Aloe Vera Drug Interactions
Oral aloe vera may interact with certain medications. In some cases, it can increase the concentration of the drug in the bloodstream (along with the risk of side effects). In others, it may reduce the concentration of the drug in the bloodstream (along with the drug's effectiveness).
If you take any of the following medications, talk to your healthcare provider before using any oral aloe vera product:
Laxatives
Diabetes medications, including insulin and Glucophage (metformin)
Diuretics ("water pills"), such as Lasix (furosemide)
Heart rhythm medications, such as Lanoxin (digoxin)
Anticoagulants ("blood thinners") such as aspirin and Coumadin (warfarin)
Precautions and Contraindications
Stimulant laxatives are used with extreme caution during pregnancy and only for the short-term relief of constipation. Because aloe vera latex and whole-leaf aloe vera extract have similar properties, the same precautions should be taken. The overuse of stimulant laxatives can induce uterine contractions and increase the risk of miscarriage or preterm birth.
Oral aloe vera products may be unsafe during pregnancy or breastfeeding and should be avoided.
Recommended Dosage
There are no recommended doses of aloe vera in any form.
Aloe vera products for the skin can vary in concentration from as little as 0.5% to over 99%. There is no evidence that lower concentrations are less effective than higher concentrations. As a rule of thumb, start with the lowest possible dose and increase gradually if needed, never exceeding the manufacturer's recommended dose.
Oral formulations of aloe vera include capsules, extracts, powders, and juices. To be safe, follow the manufacturer's dosing instructions, particularly with aloe vera latex and whole-leaf extract supplements.
How to Use Aloe Vera
The National Center for Complementary and Integrative Health suggests that the safest way to use aloe vera is topically but accedes that it can be used orally with the appropriate precautions.
How to Apply to the Skin
Here is how to use fresh aloe vera for skin conditions:
Snip one of the leaves close to the bottom of the plant.Put the cut side down in a glass to allow the latex to drain for about 10 minutes and discard it.Remove the leaf spikes and use a vegetable peeler to get to the clear gel inside.Scoop out the gel and store it in a clean, sealable container in the fridge for up to two weeks.Place a small amount of gel on your fingertips and gently work it in with circular motions.If using it as a facial cleanser, rinse with cool water and gently pat your skin dry.If using it as a facial moisturizer, gently spread a thin layer of gel onto the skin and allow it to dry.

How to Take by Mouth
Whole-leaf aloe vera extract and aloe latex should generally be avoided due to the potential risks. For safety's sake, limit yourself to commercial preparations designed specifically for oral use, such as aloe vera gels and juices.
Commercial preparations are generally safer because the dose is controlled. Even so, you can make aloe vera juice by following these steps:
Snip a leaf close to the bottom of the plant and wash thoroughly with water.Cut the leaf into 1-inch cubes.Place six to eight 1-inch cubes in a blender with 6 cups of filtered or distilled water.Blend thoroughly.Strain the juice and add sweetener and lemon if desired.
Some studies suggest that doses of up to 90 milliliters (3 fluid ounces) daily are well tolerated and safe.
Consumer Safety
If purchasing an aloe vera supplement or remedy, look for products that have been submitted for certification by an independent certifying body like U.S. Pharmacopeia (US), ConsumerLab, or NSF International. Certification by these authorities ensures that the product is non-contaminated and contains nothing but the ingredients listed on the product label.
Summary
Aloe vera is a succulent plant whose gel may aid with wound healing, improve skin texture, reduce wrinkles, and prevent cavities when applied topically. When taken orally, there is evidence that it can treat constipation and acid reflux and help lower cholesterol and blood sugar.
There are no guidelines for the appropriate use of aloe vera in any form. As a general rule, follow the manufacturer's guidelines and avoid the internal use of whole-leaf aloe vera extract or aloe vera latex which can be toxic to the liver and kidneys.

Aloe Vera Plant Care: How to Take Care of Aloe Vera Plants
Catherine Boeckmann
January 16, 2024
Learn all about aloe vera plant care—from how to care for aloe vera to how to grow this succulent outdoors and indoors in your home. Aloe vera is so rewarding! The juice from their leaves has medicinal purposes and can be used to relieve pain from scrapes and burns. See our Aloe Vera Plant Guide.About Aloe VeraAloe vera is a succulent plant species of the genus Aloe. The plant is stemless or short-stemmed with thick, greenish, fleshy leaves that fan out from the plant’s central stem. The margin of the leaf is serrated with small teeth. Before you buy an aloe, note that you’ll need a location that offers bright, indirect sunlight (or artificial sunlight). Direct sunlight can dry out the plant too much and turn its fleshy leaves yellow, so you may need to water more often if your aloe lives in an exceedingly sunny spot.Keep the aloe vera plant in a pot near a kitchen window for periodic use.WARNING: The gel from aloe vera leaves can be used topically but should NOT be eaten by people or pets. It can cause unpleasant symptoms such as nausea or indigestion and may even be toxic in larger quantities.

Planting
Before Planting Aloe VeraIt’s important to choose the right type of container. A pot made from terra-cotta or similar porous material is recommended, as it will allow the soil to dry thoroughly between waterings and will also be heavy enough to keep the plant from tipping over. A plastic or glazed pot may also be used, though these will hold more moisture.When choosing a container, pick one with at least one drainage hole in the bottom. This is key, as the hole will allow excess water to drain out. Aloe vera plants are hardy, but a lack of proper drainage can cause rot and wilting, which is easily the most common cause of death for this plant.Select a container that’s about as wide as it is deep. If your aloe plant has a stem, choose a container deep enough to plant the entire stem under the soil.Aloe vera plants are succulents, so use a well-draining potting mix, such as those made for cacti and succulents. Do not use gardening soil. A good mix should contain perlite, lava rock, chunks of bark, or all three.A layer of gravel, clay balls, or any other “drainage” material in the bottom of the pot is not necessary. This only takes up space that the roots could otherwise be using. A drainage hole is drainage enough!(Optional) To encourage your aloe to put out new roots after planting, dust the stem of the plant with a rooting hormone powder. Rooting hormone can be found at a local garden center or hardware store or bought online.How to Plant (or Repot) an Aloe Vera PlantIf your aloe plant has grown leggy, has gotten too large, or simply needs an upgrade, it’s time to repot it. Here’s how:Prepare your pot. After giving the new pot a quick rinse (or a good scrub if it’s a pot you’ve used before) and letting it dry thoroughly, place a small piece of screen over the drainage hole; this will keep the soil from falling out the bottom and will allow water to drain properly. A doubled-up piece of paper towel or newspaper can also work in a pinch, though these will break down over time.Prepare your plant. Remove the aloe vera plant from its current pot and brush away any excess dirt from the roots, being careful not to damage the roots.If your plant has any pups, remove them now. (See this page’s “Care” section for instructions on removing and potting pups.) If your plant has a very long, spindly stem that won’t fit in the pot, it is possible to trim the stem off partially. Note that this is risky and could kill the plant. To trim the stem: Cut off part of the stem, leaving as much as possible on the plant. Next, place the bare plant in a warm area that gets indirect light. After several days, a callous will form over the wound. At this point, continue with the repotting instructions below.Plant your plant. Fill the pot about a third of the way with a well-draining potting mix, then place your plant in the soil. Continue filling in the soil around the plant, bearing in mind that you should leave at least 3/4 of an inch of space between the top of the soil and the rim of the pot. The bottom leaves of the aloe plant should rest just above the soil, too. Do not water after planting.Ignore your plant (temporarily). After you’ve placed your aloe in its new pot, don’t water it for at least a week. This will decrease the chance of inducing rot and give the plant time to put out new roots. Until the plant seems to be rooted and happy, please keep it in a warm place that receives bright but indirect light.
Growing
How to Care for an Aloe Vera PlantLighting: Place in bright, indirect sunlight or artificial light. A western or southern window is ideal. Aloe that are kept in low light often grow leggy.Temperature: Aloe vera does best in temperatures between 55 and 80°F (13 and 27°C). The temperatures of most homes and apartments are ideal. From May to September, you can bring your plant outdoors without any problems, but do bring it back inside in the evening if nights are cold.Fertilizing: Fertilize sparingly (no more than once a month), and only in the spring and summer, with a balanced houseplant formula mixed at 1/2 strength.Repotting: Repot when root bound, following the instructions given in “Planting” above. Watering Aloe VeraWatering is the most challenging part of keeping aloe vera healthy, but it’s certainly not rocket science! The aloe is a succulent plant accustomed to arid environments, but its thick leaves still need sufficient water.Water aloe vera plants deeply but infrequently. In other words, the soil should feel moist after watering but should be allowed to dry out to some extent before you water again. If the soil stays overly wet, the plant’s roots can rot.To ensure that you’re not overwatering your plant, allow the top third of potting soil to dry out between waterings. For example, if your plant is kept in 6 inches of potting soil, allow the top 2 inches to dry out before watering again. (Use your finger to test the dryness of the soil.)Generally speaking, plan to water your aloe plant about every 2-3 weeks in the spring and summer and even more sparingly during the fall and winter. One rule of thumb for fall and winter watering is to roughly double the time between waterings (compared to your summer watering schedule). In other words, if you water every two weeks in summer, water every four weeks in winter.When watering, some excess water may run out of the bottom of the pot. Let the pot sit in this water so the soil absorbs as much as possible. Wait 10-15 minutes, then dump any remaining water. Photo by cgdeaw/ShutterstockRemoving & Replanting Aloe Vera Offsets (Pups)Mature aloe vera plants often produce offsets— plantlets, pups, or “babies”—that can be removed to produce an entirely new plant (a clone of the mother plant, technically).Find where the offsets are attached to the mother plant and separate them using pruning shears, scissors, or a sharp knife. Leave at least an inch of stem on the offset. Allow the offsets to sit out of the soil for several days; this lets the offset form a callous over the cut, which helps to protect it from rot. Keep the offsets in a warm location with indirect light during this time.Once the offsets have formed callouses, pot them in a standard succulent potting mix. The soil should be well-draining.Put the newly potted pups in a sunny location. Wait at least a week to water and keep the soil on the dry side.How to Get Your Aloe Vera to FlowerMature aloe vera plants occasionally produce a tall flower spike—called an inflorescence—from which dozens of tubular yellow or red blossoms appear. This certainly adds another level of interest to the already lovely aloe!Unfortunately, a bloom is rarely achievable with aloes that are kept as houseplants since the plant requires nearly ideal conditions to produce flowers: lots of light, sufficient water, and the right temperature range. Due to these requirements (mainly lighting), aloe flowers are usually only seen on plants grown outdoors year-round in warm climates. To give your aloe the best shot at flowering:Provide it with as much light as possible, especially during spring and summer. Aloes can be kept outdoors in full sun during the summer when temperatures are above 70°F (21°C). Bring the aloe inside if nighttime temps threaten to drop below 60°F (16°C).Note: Don’t move your aloe from indoors to full sun right away; it needs time to adjust to the intense light, or it may cause sunburn. Allow it to sit in partial shade for about a week before moving it to a brighter location.Ensure the plant is getting the right amount of water—enough to keep it from drying out completely but not enough to drown it! If the plant’s being kept outdoors, make sure that it’s not getting consistently soaked by summer rains.Give your aloe a proper dormancy period in the fall and winter. Aloe tends to bloom in late winter or early spring, so giving them a period of rest consisting of less frequent watering and cooler temperatures may encourage them to flower.Don’t be surprised if it still doesn’t flower. Despite our best efforts, indoor conditions just aren’t ideal for most aloes, so don’t be surprised if yours simply refuses to bloom!
Recommended Varieties
Especially attractive Aloe include:Tiger or Partridge-Breasted Aloe (Aloe variegata) – A compact aloe characterized by short, smooth leaves with uneven white stripes.Lace Aloe (Aloe aristata) – A small plant with white-spotted, finely sawtoothed leaves.Blue Aloe (Aloe glauca) – A larger aloe species with silver-blue leaves.
Harvesting
Aloe Vera GelTo make use of the aloe vera plant’s soothing properties, remove a mature leaf from the plant and cut it lengthwise. Squeeze the gel out of the leaf and apply it to your burn, or lay the opened leaf gel side–down on the affected area. Learn more about aloe vera’s healing properties.Do not ingest the gel, as it can cause nausea and other unpleasant symptoms.

The tap root on my aloe is huge! Can't find a deep enough pot for it. So the plant itself sits tilted, in the pot. What can I do? I live in zone 6, so I can't plant it outside.

Before transplanting, you can cut back both the large taproot and the smaller horizontal roots; especially focus on removing any dead or rotting roots. Although aloe is quite resilient about pruning, trim only up to about 1/3 of the rootball at a time (leaving 2/3 intact). Aloe likes to be snug in its pot and should fill the new pot about 2/3 full. After the roots are cut, some people allow the roots to air dry for a day or two, so that the wound starts to heals over a bit before placing the plant in new growing medium; this can help to prevent diseases, etc., from entering through the cuts. If you transplant immediately after pruning the roots, hold off on watering for a few days, to discourage rot. Hope this helps!

Aloes usually have a shallow, wide root system, so a deep taproot is a mystery! Have you tried online sources for indoor plant pots? Although local stores may not have just the right size for your plant, perhaps online might offer a wider selection. Try to find one in which the roots will take up about 2 inches beyond the deepest root, and about 1 to 2 inches between the plant and the container edge. Some people have fun making their own pots, or repurposing items, such as buckets, etc., to use as planters. If you’d like to try that, be sure to add a drainage hole to the container, if needed.

Aloes drop leaves when they are overwatered. Succulents need very little water. Let it dry out. Repot in lightly dampened soil. Don’t water it until it dries out.

Good article! I just brought an aloe vera home from the supermarket and in only a couple of days it stretched out towards the light, which was unexpected for a succulent!?
Its a fairly bright westward window. I wanted to say that I learned not to use aloe directly from the plant, but let the cut off leaf "bleedcin a glass of water a few hours first. It will turn milky as the Aloe releases latex which is naturally generated in the leaves and can cause irritation.
Once the latex is depleted the pulp or gel can be used to treat skin, or a piece of cut leaf can be taped to a wound with a bandaid or bandage. Removingnthe latex (over night to be sure) also makes it edible without real risk of nausea etc. Just don't overdo it, a half teaspoonspoon of gel in a smoothy is enough.
You don't want to ingest latex. Or pour it on a wound.
I live in a nordic climate so they get leggy in winter, but I shall try out a supplememtary led light and see if that helps.
Question: do I need to repot my plant? It's still as it came from the store a few days ago.
Thank you!

It is cultivated in subtropical regions around the world, including the southern border areas of Texas, New Mexico, Arizona, and California.
Historically, aloe has been used for skin conditions and was thought to improve baldness and promote wound healing.
Aloe is used topically (applied to the skin) and orally. Topical use of aloe is promoted for acne, lichen planus (a very itchy rash on the skin or in the mouth), oral submucous fibrosis, burning mouth syndrome, burns, and radiation-induced skin toxicity. Oral use of aloe is promoted for weight loss, diabetes, hepatitis, and inflammatory bowel disease (a group of conditions caused by gut inflammation that includes Crohn’s disease and ulcerative colitis).
In 2002, the U.S. Food and Drug Administration issued a ruling that required manufacturers to remove aloe from over-the-counter laxative products because of a lack of safety data.
How Much Do We Know?
A number of studies have investigated the usefulness of aloe as a dietary supplement or a topical product for health purposes in people.
What Have We Learned?
Clinical research suggests that topical application of an aloe-based gel twice daily (along with medical soap and tretinoin gel) may improve acne.
Clinical research suggests topical application of aloe gel may speed burn healing. There also is evidence that treatment with aloe vera may reduce pain from burns.
Research suggests topical use of aloe also may help people with herpes simplex, lichen planus, or psoriasis.
Three trials (with a total of 236 adult participants) have evaluated the use of oral doses of aloe vera for symptoms of irritable bowel syndrome. Results from one trial showed a benefit; the other two trials showed no benefit of aloe vera over placebo.
In a small European study, 44 adults with ulcerative colitis were randomly assigned to receive aloe vera gel or a placebo twice daily for a month. Almost half of the people treated with aloe vera responded to the treatment whereas 14 percent of those treated with placebo responded.
Aloe vera has been studied in clinical (human) trials for diabetic foot ulcers and dental plaque, but there’s not enough scientific evidence to show whether aloe vera is helpful for these conditions. A 2009 review article examined data from a mix of laboratory, animal, and clinical trials and concluded that more research is necessary to explore aloe’s clinical effectiveness for a number of different skin conditions.
What Do We Know About Safety?
Topical use of aloe gel is generally well tolerated. However, there have been occasional reports of burning, itching, and eczema with topical use of aloe gel. Oral use of aloe latex can cause abdominal pain and cramps. Oral consumption of aloe leaf extracts (for as little as 3 weeks and as long as 5 years) has been related to cases of acute hepatitis.
Animal studies have noted an association between aloe vera leaf extract taken orally and gastrointestinal cancer in rats and mice; however, concerns were expressed about the differences in the product used in that study and those commonly used by consumers. Thus, more research is needed to assess the relevance to human health.
Overuse of aloe latex may increase the risk of adverse effects from the drug digoxin, used for some heart problems.
Aloe—both in gel and latex form—when taken by mouth may be unsafe during pregnancy and while breastfeeding.

Diet & NutritionAloe Vera 101: A Complete GuideByMoira LawlerMedically ReviewedbyJustin Laube, MDon March 14, 2023DefinitionTypesJump to More TopicsBenefitsWeight LossSelect and StoreHow to UseRisksGrow Your OwnSummaryAloe vera is a popular sunburn remedy, but that may not be all this ingredient is good for.Ekaterina Klishevnik/iStockThere are more than 300 species of aloe plant, but Aloe barbadensis (aka aloe vera) is the best known and most prized in the health and beauty worlds for its internal and topical healing properties, according to an article in the Journal of Pharmacy and BioAllied Sciences.The spiky succulent plant is native to dry regions and tropical climates in Africa, Asia, Europe, and the southern and western parts of the United States.Many centuries ago, people realized the plant had more to offer than its good looks. The gel and juice found inside aloe vera became a popular herbal remedy, used to treat everything from skin disorders to digestive problems, according to an article in SAGE Open Medicine published in September 2019.Let’s take a look at the long history of aloe vera, its uses, and its potential benefits.What Is Aloe Vera?Aloe vera has been known for its healing properties and medicinal uses for at least 6,000 years. In the early days, it was considered a “plant of immortality” and was presented to Egyptian pharaohs as a funeral gift, according to the National Center for Complementary and Integrative Health (NCCIH).Over time, groups from many geographical areas have used aloe vera, including people of India, China, Mexico, and North America, too, per a chapter in Herbal Medicine: Biomolecular and Clinical Aspects.Aloe plants, which go by a few common names such as “burn plant,” “lily of the desert,” and “elephant’s gall” — have been used traditionally to treat wounds, hair loss, hemorrhoids, and digestive issues.These days, aloe has an entire industry behind it. Its juice and leaf gel is used in cosmetics and personal-care products such as moisturizer, soap, shaving cream, and suntan lotion. The aloe vera products that probably come readily to mind are the bright green gels that are stocked on drugstore shelves. You’ve probably used it to soothe a nasty sunburn.Aloe vera is also available in supplement form, and is purported to offer similar benefits to the skin and digestive system as other preparations of the plant.Common Questions & AnswersWhat is aloe vera good for?Aloe vera may help with digestion, treatment of skin conditions such as acne or psoriasis, sunburn relief, wound healing, heartburn, and blood sugar control.Is it safe to drink aloe vera?Possibly. Aloe vera comes in many forms, and packaged aloe vera drinks are one of the latest aloe trends. Just make sure the drink includes aloe vera and not aloe latex, which comes with a host of potential negative side effects.Is it okay to use aloe vera every day?Topically, it is safe to use aloe vera every day, and there is no limit to how often you should use it. It’s also tolerated by most people and rarely causes an allergic reaction. For oral intake, it’s theoretically safe but poses more risk.Can I leave aloe vera on my face all day?Yes, you can. It may help ease inflamed or irritated skin, such as sunburned skin. Look for a product that’s mainly made of aloe and doesn’t contain alcohol, additives, or fragrance, because these will dry out your skin.Can you use aloe vera straight from the plant?Yes, you can use aloe vera topically straight from the plant. Simply break off the leaf and squeeze out the gel. Or you can find it at a drugstore.Types of Aloe VeraThere are two medicinally useful parts of the aloe vera plant: aloe leaf and aloe latex, per the NCCIH.Aloe LeafThe fleshy leaves are filled with a clear gel, which is extracted from the plant and usually used in different aloe vera preparations:As a topical medication on the skin to treat burns and various skin conditionsIn liquid or capsule form for oral useThere are even more options these days: The latest trend is aloe vera beverages, such as aloe vera juice, which is made simply by extracting the aloe vera gel from the leaves and mixing it with water, according to the Cleveland Clinic. Aloe vera on its own can have a bitter taste, so some brands will add flavor or sweeteners to the bottle. Take a look at the bottle’s ingredients to make sure it’s not loaded with added sugar.Aloe LatexThis is the yellow pulp that’s found just under the outer surface of the plant leaf. Mayo Clinic writes that aloe latex has been shown to have laxative effects, and it’s usually taken orally to treat constipation.

Potential Health Benefits of Aloe VeraAccording to the NCCIH, there’s not enough evidence to prove aloe vera can treat all the health issues it’s said to help with. Some of the many and varied claims include the following.Better DigestionAloe latex contains aloin, an anthraquinone that gives the plant its laxative properties, and which may relieve constipation, according to the National Institute of Environmental Health Sciences (NIEHS).Constipation is a symptom commonly seen in primary care patients and also occurs with chronic digestive conditions like irritable bowel syndrome (IBS).A study published in JNM in October 2018 suggested that aloe vera may be useful for individuals with constipation, including those dealing with this symptom in IBS. This is because of aloe vera’s laxative effect and its ability to increase water in the intestinal lumen.Treatment of Skin Conditions Such as Psoriasis and AcneTopical aloe vera and aloe creams that contain the leaf extract can have a calming effect on the skin and have been shown to reduce itchiness and inflammation, according to the Mayo Clinic.In a past review of aloe vera, researchers found that the plant had the ability to inhibit prostaglandin E2 production. These are lipids that not only play a role in the inflammatory process but are also active in the sebaceous glands, possibly contributing to inflammatory skin conditions, other research has noted.In addition to being anti-inflammatory, aloe has antibacterial properties and promotes wound healing, which makes it a potential complementary approach to treat acne with topical application, according to a study published in May 2021 in Frontiers in Medicine. Data from the study showed that a new treatment combining aloe vera gel, a soft mask, and ultrasound led to significant improvements for patients dealing with moderate acne. A study from 2014 found that when added to the common topical acne treatment tretinoin, aloe vera gel had a more positive effect on acne than tretinoin alone.Sunburn ReliefSome people swear by a thick gel derived from aloe to calm a sunburn, but you may be surprised to learn this herbal remedy lacks concrete research results demonstrating its ability to soothe symptoms and speed recovery, as a review notes.One study, for instance, found aloe vera applied topically after laboratory-induced sunburn didn’t have an effect on reducing redness compared with a placebo. And yet this study was small and included only 20 healthy volunteers.That doesn’t mean it’s not worth trying, though, given its historical use and that it is generally safe. Indeed, you have likely experienced the gel’s cooling effect yourself, and according to the Skin Cancer Foundation, aloe vera is generally safe to use for soothing mild sunburns and doesn’t have any adverse effects. Kate Deery, a certified aesthetician with Clareo Plastic Surgery in Boston, can attest to this potential benefit, and notes its safety. “Aloe vera can be used as a mask for more inflamed or irritated skin, such as sunburned skin,” Deery says.Wound HealingAlthough aloe products may not be as effective for treating sunburns, per research, it may provide some relief after minor burns, such as a first- or second-degree burn. In a review of four controlled clinical trials consisting of 371 burn patients, researchers found that healing times for patients who applied aloe vera to their burns was about nine days shorter than in the control group. That said, these studies differed in terms of the products used and conclusions measured, so more studies on the potential effects of aloe vera on wound healing are needed before well-informed decisions can be made. Talk to your healthcare team about proper treatment for severe burns before turning to over-the-counter options like aloe vera.Less HeartburnIn one trial, researchers found that a standardized aloe vera extract in a syrup had therapeutic benefits for gastroesophageal reflux disease (GERD) and led to a decrease in symptoms such as heartburn, belching, and vomiting over a four-week period.A limited number of studies support this notion, yet the effect may be due to GERD’s link to inflammation. Aloe vera has anti-inflammatory properties, as well as antioxidant and anti-ulcer properties that have been studied in animals and patients with IBD (irritable bowel disease), as past research notes.Lower Blood SugarA past clinical trial found that 2 tablespoons of aloe vera juice every day for two weeks lowered blood sugar levels among people with type 2 diabetes. Triglyceride levels of the study participants also improved — which could be an additional benefit for those with diabetes: They're at an increased risk of heart disease, which is linked to triglyceride and cholesterol abnormalities. A more recent study suggests people with prediabetes may see similar effects on their blood sugar and lipids from aloe vera.Again, these are possible benefits based on preliminary data, so work with your healthcare team before trying aloe vera for these reasons.Can Aloe Vera Help With Weight Loss?There is some research showing that aloe may speed up metabolism, which in turn would help you burn more calories throughout the day and potentially lead to weight loss, though research is very limited at this time.Previous research found that rats who were treated with aloe vera gel powder had a significantly lower body weight and body fat percentage than those who weren’t. The researchers suspect this is because they increased their energy expenditure. Studies showing the same effect in humans, though, are lacking.Another previous study found that people with untreated diabetes or obese prediabetes who took an aloe vera gel complex reduced their body weight, insulin resistance, and body fat mass.How to Select and Store Aloe VeraAloe vera substances are considered a dietary supplement, and supplements are not regulated fully by the U.S. Food and Drug Administration (FDA) in the same way as prescription medication. That means there’s no way to know for sure whether the quality, safety, or claims from the manufacturers on the product are valid. And there are loads of products that claim to be rich in aloe vera, but many of them contain few to no active ingredients.SelectionThere is one thing to look for, however, when buying your product: the seal from the International Aloe Science Council, which is an organization that’s been active since the 1980s. Their seal on a product means the product’s aloe vera quality and purity has been tested and confirmed.StorageConsult the label on your aloe vera product to learn about the best storage method. Generally, it’s best to store aloe vera gel and aloe vera juice in a cool, not-too-humid environment, such as at room temperature or in the refrigerator. Humidity and temperature can affect the shelf-life of the product. That’s why you’ll likely find aloe vera juice in amber-colored bottles. The dark bottle, according to past research, is designed to keep light from affecting the active ingredients.
Editor’s Picks on Herbal Remedies7 Popular Supplements That May Have Hidden DangersIs Aloe Vera Juice Good for You?Taking Too Many Supplements? Here's How to Tell, and Why It Can Be Risky13 Natural Dry-Skin Remedies You Can DIY at Home
How to Use Aloe VeraBy now you may want to explore some of the potential benefits outlined above. It's best to do so in consultation with your primary doctor, nutritionist, or another healthcare provider who knows how to safely use aloe, especially if you want to try it internally rather than topically. The plant has been shown to have a few other potential uses, such as the following.As a Way to Keep Produce FreshOne study found aloe vera gel applied on the outsides of tomatoes helped delay ripening, aided in maintaining their quality and freshness, and prevented certain bacteria from growing.As a Simple MouthwashResearch has shown that aloe vera mouthwash reduces plaque formation on teeth in the short term. In the study, 300 subjects were assigned to rinse their mouths and gums with either aloe vera mouthwash, normal saline, or chlorhexidine gluconate mouthwash. Researchers found that after four days, aloe vera was just as effective at reducing dental plaque as chlorhexidine and caused no side effects. More studies are needed to assess longer-term effectiveness and safety.As a Pain RelieverThe use of aloe vera could relieve pain. Salicylic acid, found naturally in aloe vera, is a compound that gives aspirin its anti-inflammatory effects, per research. More studies are needed to explore the effectiveness of aloe vera in treating pain, but one past paper suggests that oral aloe vera may help reduce chronic pain that is not related to cancer, such as osteoarthritis pain. Meanwhile, other past research in mice found that a small amount of aloe vera applied topically may inhibit inflammation from mild irritants, though more peer-reviewed studies in humans are needed.As a Skin-Care IngredientAloe vera is an “it” ingredient as a skin treatment in the beauty and cosmetics space as well. You’ll find it in everything from moisturizers and toners to shampoos and deep conditioners. There’s even an entire line of products called Aloe Vesta, which are designed to protect sensitive skin.What’s the reason for the hype? The plant is known for supporting skin hydration, moisture, and clarity. It’s rich in antioxidants such as vitamin A, vitamin C, and vitamin E, and it contains seven of the eight essential amino acids, according to a previous article. It’s known for its anti-inflammatory properties, though some critics say more research is needed before we can say that for sure.A past uncontrolled study found that aloe has anti-aging potential: The researchers gave 30 women doses of oral aloe vera gel twice a day for three months. The women saw significant improvements in their wrinkles and the elasticity of their skin. Researchers posited that this effect was from an increase in collagen production.You’ll also find hair-care products containing aloe vera. According to the website Byrdie, some beauty pros apply the gel extracts found inside the leaves of the mother plant directly to their hair and use it as a deep conditioner. It can leave a residue behind though, so be sure to rinse it out thoroughly, and if you have skin conditions it's best to seek help from a dermatologist before putting raw plant products on your skin.Health Risks of Aloe VeraAloe gel (the part of the plant that’s commonly found in creams and moisturizers) is generally safe to use and contains therapeutic properties for the skin when it’s applied topically.Aloe latex, however, can be dangerous. Taking aloe latex orally can lead to cramps and diarrhea, and it could make other oral medications you’re taking less effective, according to the NCCIH.Aloe latex can lead to more serious problems, too. A dose of even just 1 gram (g) orally per day for several days could end up causing kidney damage and may even be fatal, per the Mayo Clinic. It also can lower blood glucose levels, so people with type 2 diabetes need to be careful and talk to their doctor before incorporating aloe latex into their care regimen.Another potential negative for aloe latex: It may have cancer-promoting effects. A study from the National Toxicology Program found that whole-leaf aloe vera extract created cancerous tumors within the large intestines of rats. But don’t be alarmed. The study didn’t involve humans, and the National Institute of Environmental Health Sciences says there’s nothing currently in the literature that suggests researchers would find the same results in humans.The rats in the study drank water containing 60 parts per million (ppm) of aloin every day. That’s much higher than the 10 ppm that the industry tends to set as their limit, so it’s not likely you’d reach unsafe levels, per the NIEHS.Is It Possible to Be Allergic to Aloe Vera?It is possible to be allergic to aloe vera, though it’s rare, according to Mount Sinai. An aloe allergy could be dangerous, however. Some signs of an allergic reaction to aloe include a rash, throat tightness, difficulty breathing, or chest pain.Growing Your Own Aloe VeraGood news for nongreen thumbs: Aloe vera is a cinch to grow as a houseplant at home.Aloe vera is a hardy succulent plant that prefers dry, warm climates, so it doesn’t need to be watered every day. A little neglect in watering isn’t going to hurt it — in fact, watering sparingly may actually help, because this drought-loving plant lives best in dry conditions, per the Missouri Botanical Garden. You should be careful not to overwater the plant, and if you keep the plant outdoors, be sure to cover it when it rains.Aloe vera plants grow to be one to two feet high and up to one foot wide, and prefer the sun and tropical climates. When in bright sunlight, the plant will flower. Unless you live in Hawaii, Southern California, Arizona, or southern Florida, you won’t be able to leave it outdoors all year. But you can easily leave it in a pot and bring it inside in the winter or whenever the temperature drops (ideally anytime it gets close to 50 degrees F or cooler). Sunlight is key to a healthy aloe vera plant, so position it outside in a sunny spot or indoors on a windowsill, advises the site One Green Planet.When planting your aloe vera plant in a pot, choose a shallow, wide bowl so the roots have room to move and spread in the soil as they grow. Seedlings will grow around the base of the plant, which you can then take and plant in a new pot.

SummaryIf you’re interested in using aloe vera, first turn to premade over-the-counter options — particularly those that can be applied topically. These may offer benefits with low odds of side effects. As for oral aloe vera, talk to your healthcare team first, as these products are riskier.Additional reporting by Valencia Higuera.Editorial Sources and Fact-CheckingEveryday Health follows strict sourcing guidelines to ensure the accuracy of its content, outlined in our editorial policy.

Aloe vera, commonly grown as a houseplant, is known for its leaves which contain a soothing gel used on sunburns and other skin irritations. With over 300 species (the most common being Aloe barbadensis miller), this tropical succulent features fleshy lance-shape leaves with jagged edges that grow out from a basal rosette.
Given the right growing conditions, spiky flowers will appear on the end of stalks in shades of yellow, red, or orange.

Aloe Vera Care
Aloe vera needs sandy soil or a cactus potting medium to thrive in containers. When grown outdoors in zones 10 through 12, plant this succulent next to others with similar needs. Blend aloe into a xeriscaped border planting, or make it an entryway focal point by potting it on its own. Potted aloe looks nice on decks and patios where it also comes in handy for use on emergency burns and bites. Outdoors, blooming may occur in late spring or early summer; blooms generally don't appear on potted indoor specimens. Either way, the plant needs to be very mature in order to bloom at all and, even still, may not bloom every year, especially if the leaves are being harvested for use. Aloe requires little watering and virtually no fertilizing, making it an easy-care houseplant for beginner gardeners.

Light
Aloe Vera needs bright, natural light in order to thrive. Outdoors, aim for up to six hours of full sun, with a small shade reprieve in the afternoon.
When grown inside, aloe should be placed in a window with bright, indirect sunlight. Direct sun can burn its tender skin, yet lack of light will cause the plant to grow leggy and weaken its leaves, causing them to crease.
Soil
In its natural habitat, aloe vera commonly grows in nutrient-poor soil conditions, on sandy slopes with guaranteed drainage. Ensure proper drainage in a pot by using a cactus potting medium or traditional potting soil mixed with perlite and coarse sand. Aloe prefers its soil slightly acidic, hovering around 6.0, but it is highly adaptable and can also grow in neutral or alkaline soils, as well.
Water
Aloe prefers to be watered regularly, as long as the soil dries out completely in between waterings. If the soil remains dry for long periods of time, the leaves will shrivel and pucker slightly.
Aloe vera goes dormant in the winter and won’t require any water at all, provided it received sufficient water during its growing season. If your climate is rainy during the winter, consider planting aloe in gravel or stones. This will allow the water to run off and prevent rot.
Temperature and Humidity
Aloe grows naturally in arid, tropical, and semi-tropical environments, so mimicking these conditions will allow it to thrive. Aim for a temperature between 55°F and 85°F and don't leave your container plant outdoors if nights are forecasted to dip below 40°F.
Aloe can handle dry air just fine and does not require extra humidity. Forty percent relative humidity is perfect.
Fertilizer
Aloe vera grows best in poor soil conditions (this plant has adapted to nutritionally poor desert soil) and does not require any fertilization at all. That said, feeding potted aloe once a year each spring may help maintain vibrant growth.
A liquid 10-40-10 houseplant fertilizer, diluted to half strength, works best for an annual feeding. Outdoors, aloe usually thrives without any fertilization.
Types of Aloe Vera
Over 500 species of aloe exist, but not all are cultivated for growing in the garden or home. Some have thorny leaves, some trail and climb, and others are round in shape.
Here are a few gardeners' favorites:
Aloe polyphylla, or "spiral aloe," is a captivating succulent that grows in a spiral and bears orange flowers. This large, egg-shaped plant (20 to 24 inches round) hugs the ground and features gray-green leaves with purple tips.
The mid-sized Aloe aculeata (3 feet tall and wide when mature) grows thick, broad leaves with teeth, or thorns, on both sides. This variety features yellow or orange flowers and can be found growing naturally in rocky areas and in the grasslands of Africa between 1500 and 5600 feet.
Aloe ciliaris, also known as "climbing aloe," is a succulent vine with stems that can grow up to 30 feet long. It bears bright orange tubular flowers near the terminal ends of the leaves, and is sometimes planted in drought-stricken landscapes as a fire block.
Aloe brevifolia, or "short-leaf aloe," is round in shape with thick, triangular leaves that have a bluish hue and orange tips. This variety grows less than a foot tall, but its golden rosettes make it a popular landscape addition.
Pruning
Aloe vera needs pruning only if the leaves are shriveled and dead. You can also prune those damaged by environmental factors. If the outer leaves of your aloe vera plant go brown at the tips, cut them back, as well.
To do so, use clean garden shears and either cut off only the affected tip, or prune the entire leaf altogether at its base. Pruning leaves at the base—either dead or alive—will encourage new growth while also making the plant aesthetically pleasing. Never cut an aloe leaf in its center.
Propagating Aloe Vera
Aloe vera is best propagated by replanting the offsets (the pups) that develop at the base of the plant. Mature plants will often produce many pups, making it easy for you to relocate them to other pots or parts of the garden, or you can gift them to friends.
Here's how to propagate aloe vera from pups:
Gather gloves, a trowel, a pot, and a cactus potting medium.Put on your gloves and fill the pot with potting mix.Locate the pups at the base of the mother plant. Using a trowel, pry up a pup and sever the taproot that connects it to the mother. (Some pups may have more extensive root systems than others. Some may have no roots at all. All will grow fine, either way.)Lay the pup flat and dry it in a sunny window for a few days to allow any broken cuts to callus over.Plant the pup in the pot, taking care to cover any roots. Backfill the soil just below the main crown (where the leaves fan out).Water the plant and place it in a sunny window. It may take three to four months to grow roots. Be patient.
Potting and Repotting Aloe Vera
Aloe vera has a shallow and wide root system that likes to spread out close to the surface. As the plant grows and needs repotting, it's best to move up to a wider pot, rather than a deeper one. Repot your aloe when it becomes rootbound or if its pups seem to be overcrowded.
Carefully remove the mother plant and pups from their container, taking care not to damage the leaves. Pull or cut the pups from the mother, allow them to dry, and then replant them on their own. Fill a wider pot with a cactus soil medium. Repot the mother so that all of the roots are covered and the soil line hits just below the main crown. Water all the plants thoroughly and allow the soil to dry completely before any subsequent waterings.
Overwintering
Aloe vera cannot tolerate frost, so if you live in a cold climate, grow this plant in containers and bring it inside for the winter. Outdoor plants within their hardiness zones can be left alone in the ground to remain unwatered throughout their dormant period.
If an unexpected frost is predicted, cover your aloe plants with sheets or blankets to keep them warm until the threat of frost has passed.
Common Pests & Plant Diseases
Aloe vera may fall victim to mealybugs, aloe scale, and aloe mites. Mealybugs congregate at the base of the plant where they secrete a sticky substance that provides an environment for mold to move in. Scale seldom kills the plant, but creates unsightly grey ridges on the leaves. Mites can go unnoticed until cancerous galls form as a result of their feeding.
Wipe mealybugs away with a soft cloth, after spraying the plant with water. Scale can be eradicated by whipping up a solution of 1 tablespoon insecticidal soap, 1 cup isopropyl alcohol, and 1 cup of water. Spray scale-infected leaves with this solution every three days for 14 days. For mites, prune the infected tissue to keep this plant, and any others around it, safe from harm.
Cool temperatures and high humidity can bring on a bout of aloe rust, a fungal disease that presents as yellow spots on the leaves which eventually expand and turn brown. This disease is self-limiting and usually doesn't require treatment. Bacterial soft rot can also move in and is a fatal disease. There is no treatment for this, but prevention starts by not overwatering.
How to Get Aloe Vera to Bloom
Aloe flowers on a stiff stalk up to three feet high. Clusters of tubular yellow or orange blossoms resemble those of red hot poker plants. Aloe vera is a finicky bloomer, though. In fact, indoor potted aloe vera may never bloom, even when it has reached the mature age of four.
To try to force a bloom, you need to recreate the plant's natural desert conditions. Exposing your plant to bright sunlight, warm temperatures, and moderate, yet infrequent, waterings will give you the best chance of blooms.
Potted plants can be placed outdoors in the summer for a better chance of flowering. Still, even when all the conditions are met, your aloe vera plant may only send up one shoot and flower, and maybe only one time seasonally.
Common Problems With Aloe Vera
Overwatering is one of the most common mistakes gardeners make with their aloe plants. Consistently wet soil contributes to root rot and mushy leaves. Rot at the roots can escalate the proliferation of bacteria or fungus, causing decay throughout the plants interior. In its most severe stages, root rot and decay cannot be treated.
Aloe leaves have also been known to bend and break. This condition provides a signal that your plant is not getting enough light to form stiff, healthy leaves. To remedy this situation, move your plant to a brighter spot, or use a fluorescent light to supplement sunshine.
FAQ
How long do aloe vera plants live?
Indoor aloe plants can live up to 12 years, if given proper care and in the proper environment. Outdoor plants, surprisingly, can last up to two decades in an environment that mimics the plant's natural habitat.
Is aloe vera a cactus?
Certain varieties of aloe have thorny leaves, making some gardeners believe this plant is a cactus. However, aloe is a succulent that has a genus of its own called Aloe.
Should I cut the brown tips off my aloe vera plant?
Yes. Brown, rotting tips provide the perfect environment for fungal growth, which will inhibit your aloe vera plant's growth. Cut brown tips to keep your aloe vera plant healthy and happy.

People have used aloe vera for thousands of years for healing and softening the skin.
There are hundreds of aloe plants, but aloe vera is unique in its ability to help you inside and out. Aloe vera is the only edible form of aloe. The aloe vera plant is native to the Arabian peninsula, but it grows throughout the world. This shrubby, pointy plant has been cultivated for its soothing gel for thousands of years.Aloe vera gel isn’t just good for skin issues. It can be blended with water to create aloe vera juice, which is full of nutrients. What Is Aloe Vera?Aloe vera is gel from the leaves of aloe plants. People have used it for thousands of years for healing and softening the skin. Aloe has also long been a folk treatment for many maladies, including constipation and skin disorders. Modern-day research into aloe vera's benefits is mixed, with some evidence showing it can cause cancer in lab animals.There are no foods that contain aloe vera, so it must be taken in supplement or gel form.Some forms of aloe vera are safer to take than others, and chronic use is discouraged.Aloe Vera BenefitsThe nutrients found in aloe vera juice can provide some health benefits. Beta-carotene is a yellow-red pigment that's found in aloe vera plants. It acts as an antioxidant that can help support eye health, including retinal and corneal function.Relieves heartburn. Heartburn is a painful condition that involves acid leaving the stomach and traveling up the esophagus. A recent study has shown that aloe vera juice can reduce the symptoms of heartburn without any uncomfortable side effects.Treats constipation. Aloe vera juice contains several compounds known to act as laxatives. While drinking aloe vera juice is unlikely to cause digestive issues in people with normal bowel movements, it has shown promise as a way to relieve constipation.May improve IBS symptoms. Aloe vera juice may be a potential treatment for irritable bowel syndrome (IBS). This condition involves the inflammation of the intestine, leading to pain and other issues. Aloe has been shown to have anti-inflammatory properties. In one trial, people with IBS who drank aloe vera juice said some of their symptoms improved. However, scientists need to do more research. Aloe Vera NutritionAloe vera juice is a rich source of antioxidants, which help fight free radicals. This lowers oxidative stress on your body and reduces the risk of chronic conditions such as diabetes, heart disease, and cancer. Aloe vera juice is also an excellent source of:Vitamin CVitamin AVitamin EBeta-caroteneFolic acidCalciumMagnesiumNutrients per serving One 8-ounce serving of pure aloe vera juice includes:Calories: 8Protein: Less than 1 gramFat: Less than 1 gramCarbohydrates: 3 gramsFiber: 2 gramsSugar: Less than 1 gramAloe vera juice contains high levels of magnesium, which is a vital nutrient for nerve and muscle use. Magnesium helps your body with more than 300 different enzyme reactions, including those that regulate your blood pressure. It also helps regulate heart rhythm. Aloe Vera UsesResearch backs up the ancient use of topical aloe vera as a skin treatment, at least for specific conditions. Studies have shown that aloe gel might be effective in treating skin conditions including:PsoriasisSeborrheaDandruffMinor burnsSkin abrasionsSkin injured by radiationHerpes soresAcneAnal fissures There’s also strong evidence that aloe vera juice, which contains latex, taken by mouth is a powerful laxative. In fact, aloe juice was once sold in over-the-counter constipation drugs. But because aloe vera’s safety was not well-established, the FDA ordered in 2002 that over-the-counter laxatives containing aloe vera either be reformulated or removed from store shelves.Aloe vera gel taken by mouth seems to help lower blood sugar levels in people with diabetes. It may also help to lower cholesterol. The results of aloe vera studies for other medical conditions have been less clear.How much aloe vera should you use?Creams and gels with aloe vera vary in dosage. Some creams for minor burns have just 0.5% aloe vera. Others used for psoriasis may contain as much as 70% aloe vera. As an oral supplement, it has no set dose.For constipation, some use 100-200 milligrams of aloe vera juice -- or 50 milligrams of aloe vera extract -- daily as needed. For diabetes, 1 tablespoon of the gel has been used daily. High oral doses of aloe vera or aloe vera latex are dangerous. Ask your doctor for advice on how to use aloe vera.How to Prepare Aloe Vera JuiceAloe vera juice can be found in supermarkets around the country. It typically comes in bottles, mixed with water to make it less thick. It’s also possible to make aloe vera juice yourself. Take an aloe vera spike from a plant and trim the pointed edges off of the sides. Then, carefully slice off the skin on the flat side of the leaf and remove the gel from inside. This gel is the edible part of the plant.Make sure you remove all traces of the skin from the plant. The skin adds a bitter, unpleasant flavor. You can rinse the gel under running water to help remove all traces of it. Once you have the gel, you can toss it in a blender. Blend until smooth, then add water until it reaches the thickness you like. The result is a fresh, clean-tasting beverage.Here are some ways to add aloe vera juice to your diet:Drink the juice on its own.Add aloe vera juice to smoothies.Use aloe vera juice in cocktails.Mix aloe vera juice into lemonade.Use aloe vera juice in gelatin.Aloe Vera RisksTalk to your doctor before using it. Researchers warn against the chronic use of aloe vera. But if the aloe vera product is free of aloin -- an extract of the plant that has been found to cause colorectal cancer in rats -- it may be OK as a topical remedy for sunburn. Aloin is found between the outer leaf of the aloe plant and the gel inside.Side effects. Topical aloe vera might irritate your skin. Oral aloe vera, which has a laxative effect, can cause cramping and diarrhea. This may cause electrolyte imbalances in the blood of people who ingest aloe vera for more than a few days. It can also stain the colon, making it hard to get a good look at the colon during a colonoscopy. So avoid it for a month before having a colonoscopy. Aloe vera gel, for topical or oral use, should be free of aloin, which can irritate the gastrointestinal tract.Risks. Do not apply topical aloe vera to deep cuts or severe burns. People allergic to garlic, onions, or tulips are more likely to be allergic to aloe. High doses of oral aloe vera are dangerous. Don’t take oral aloe vera if you have intestinal problems, heart disease, hemorrhoids, kidney problems, diabetes, or electrolyte imbalances.Interactions. If you take any drugs regularly, talk to your doctor before you start using aloe vera supplements. They could interact with medicines and supplements like diabetes drugs, heart drugs, laxatives, steroids, and licorice root. The oral use of aloe vera gel may also block the absorption of medicines taken at the same time.Given the lack of evidence about its safety, aloe vera supplements should not be used orally by children and by women who are pregnant or breastfeeding.

AloeBy Mayo Clinic StaffOverview
Aloe, a plant, produces two substances used in health care products — clear gel and yellow latex.
People primarily use aloe's clear gel topically in creams and ointments to treat burns, the skin condition psoriasis and even acne. Some also take the gel orally to treat certain conditions. Aloe latex, a laxative, has been taken orally to treat constipation.
While aloe gel is generally safe when used as recommended, oral use of aloe latex poses safety concerns. In fact, taking 1 gram a day of aloe latex for several days can cause kidney damage and might be fatal.
What the research says
Research on the use of aloe for specific conditions shows:
Burns and wounds. Application of aloe gel appears to shorten the duration of wound healing for first- and second-degree burns. Aloe gel might also promote wound healing.
Acne. Research suggests that aloe gel, applied in the morning and evening in addition to the use of the topical prescription acne medicine tretinoin (Retin-A, Atralin, others), might be more effective in reducing acne than using a topical prescription alone.
Psoriasis. Aloe extract cream might reduce redness, scaling, itching and inflammation caused by mild to moderate psoriasis. You might need to use the cream several times a day for a month or more to see improvements in your skin.
Herpes simplex virus. Applying a cream containing aloe extract might help lesions heal sooner.
Oral lichen planus. Research suggests that twice-daily application of aloe gel for eight weeks might help reduce symptoms of this inflammatory condition that affects the inside of the mouth.
Constipation. Whether oral use of aloe latex is effective at treating constipation is unclear. While it acts as a laxative, aloe latex can also cause abdominal cramps and diarrhea.
Our take
Generally safe
Aloe gel is generally safe and can be effective in treating skin conditions such as burns and psoriasis.
However, avoid using aloe latex orally. Unprocessed aloe latex contains chemicals that appear to have the potential to cause cancer, and processed aloe latex might have cancer-causing compounds. Taking 1 gram a day of aloe latex for several days can cause kidney damage and might be fatal.
Safety and side effects
Aloe gel is generally considered safe when appropriately applied to the skin. It might be safe when appropriate doses are taken orally for a short time.
Aloe latex or whole-leaf extract taken orally might be unsafe and is likely unsafe in high doses. Taking 1 gram a day of aloe latex for several days can cause acute kidney failure and can be fatal. Aloe latex might also have the potential to cause cancer. Other side effects include abdominal cramps and diarrhea. Oral use of aloe latex and whole-leaf extract isn't recommended for children younger than age 12.
Interactions
Possible interactions include:
Anticoagulants and anti-platelet drugs, herbs and supplements. These types of drugs, herbs and supplements reduce blood clotting. Oral use of aloe might also slow blood clotting. Taking aloe orally with either of these types of medications might lead to increased bleeding.
Digoxin (Lanoxin). Oral use of aloe latex can decrease potassium levels. Low potassium might increase the side effects of digoxin. Don't take aloe latex and digoxin together.
Diabetes drugs. Oral use of aloe gel, when taken in combination with diabetes drugs, might increase the risk of a condition characterized by an abnormally low level of blood sugar (hypoglycemia).
Oral drugs. Oral use of aloe latex can decrease your body's absorption of other drugs. This might reduce their effectiveness.
Sevoflurane (Ultane). This anesthesia used during surgery might slow blood clotting. Oral use of aloe might have a similar effect. When used in combination, excessive bleeding during surgery is possible.
Stimulant laxatives. Oral use of aloe latex with stimulant laxatives might overstimulate your bowels. This can lead to dehydration.
Warfarin (Coumadin, Jantoven). Oral use of aloe latex can cause diarrhea. This can increase the effects of warfarin, a blood-thinning drug, and the risk of bleeding.
Water pills (diuretics). Oral use of aloe latex, a laxative, in combination with use of diuretics might decrease potassium levels too much. Potassium supplementation might be needed.

Most people are familiar with one of the most ubiquitous types of aloe, the aloe vera plant. The gel from aloe vera's fleshy leaves is so widely coveted for its cosmetic and medicinal uses that this succulent is cultivated on extensive farms in Asia, Mexico, and parts of the United States. However, the Aloe genus is large and diverse, containing over 500 aloe types native to Africa and the Arabian Peninsula, which feature the mild temperatures and arid climate that support the growth of these tough plants. Many of these lesser-known aloes can be cultivated in containers or even outdoors in frost-free zones.
Although appearances vary greatly from species to species, most aloes have thick, fleshy leaves arranged in a rosette pattern. Flowers are often tubular in shape and yellow, orange, pink, or red in color. They range from tiny ground-hugging species to those the size of small trees.
Here, learn about 21 types of aloe with tips to identify each variety and care for it in your garden.
Gardening Tip
When grown in a garden, aloe plants require a loose, gritty soil, such as that common in desert regions. If you have very rich soil, you may need to amend it with sand. Preferably, the soil should be neutral to slightly alkaline in pH. When grown in containers, aloes do best with a loose potting mix designed for succulents.

Aloe Vera (Aloe barbadensis Miller)

Aloe vera is often know for its ability to soothe a sunburn and other skin irritations, and this popular houseplant is actually a tropical succulent. While there are over 300 varieties of aloe vera, Aloe barbadensis Miller is the most commonly known. It features lance-shaped leaves and spiky flowers, and its leaves break open to reveal a green gel.

Lace Aloe (Aloe aristata)
mpalis / Getty Images
Aloe aristata stands apart from other types of aloe because it's more cold tolerant and needs more shade than most. Lace aloe plants resemble Haworthia plants with their white whiskers and bumpy leaf tubercles. The lace aloe may bounce back from temperatures as low as 19 degrees, but one thing it won't survive is soggy conditions, which will cause the plant's demise from rot. Because it's small, you can move the container plant around to keep it from getting sunburned or frozen. In the wild, lace aloe plants form a globe shape with darkened leaves in response to winter drought. Follow this natural growth pattern by withholding water in the winter, or keep it irrigated for a plump, lush plant.

Golden Toothed Aloe (Aloe nobilis)

Aloe nobilis is full of personality, with its abundant yellow spikes and rose-tipped leaves. The medium-sized rosettes may produce reddish-orange bloom spikes in very bright light. Golden toothed aloe looks handsome in a mixed dish garden with other succulent specimens.

Tiger Tooth Aloe (Aloe juvenna)

Aloe juvenna is more bark than bite: Yes, its leaves have toothy protrusions that give the plant its name, but the spikes are soft and flexible and lend more charm than defense. Like most aloe types, it likes warm to hot conditions. Happy plants produce pup offsets for propagating; the plant turn reddish-brown in response to full sun. Give your tiger tooth aloe a summer vacation outdoors, and you may earn bragging rights when it blooms with long, red flower stalks.

If you live where temperatures never dip below 25 degrees, try Aloe brevifolia as a drought-tolerant ground cover that reaches only 4 inches tall. The handsome gray leaves sometimes exhibit a tinge of orange outdoors, which looks stunning when its orange blooms appear in fall and winter. The clumping plants are deer resistant and tolerant of poor clay soil, as long as rainfall is minimal.

Red Aloe (Aloe cameronii)
Ton Rulkens / Getty Images
Aloe cameronii gets its common name, red aloe, from the exquisite coppery-red leaves that lend a vibrant sunset-hued glow to any garden. The red is enhanced by dry conditions, so don't overwater these tough plants, or they'll remain green. This type of aloe is named in honor of Kenneth Cameron, who sent it from South Africa to the Royal Botanic Gardens in England for further examination in 1854.

Aloe broomii is called snake aloe not for its toothy foliage but for its unique blossom shape. The flowers are covered with long bracts (leaves) that lend a serpentine quality. The plants have a rosette of stiff leaves edged with dark thorns, and they appreciate the same warm and dry growing conditions as most aloe types. This plant is sometimes known as mountain aloe because of its fondness for rocky slopes.

Be sure to plant Aloe dorotheae in full sun to coax the best orange and salmon colors from this vibrant cultivar. Place this low-growing aloe at the front of your border in the rock garden, or grow in a container, where it will achieve a maximum height of about 12 inches. Winter flower spikes may appear, featuring orange blooms with pale green tips. This is an endangered plant species in its native South Africa.

Malagasy Tree Aloe (Aloe vaombe)

Although many aloe types feature a rosette of leaves without stems, Aloe vaombe takes the form of a tree. The Malagasy tree aloe is native to Madagascar, but, with careful propagation methods, gardeners have been able to cultivate it in places like Arizona or north coastal New Zealand, where temperatures stay above freezing. As plants reach maturity, they produce early spring stalks of red flower clusters that attract bees, butterflies, and hummingbirds. Flowers are followed by abundant seeds, which have a high germination rate in warm, moist growing environments.

Aloe polyphylla may not be the most common type of aloe, but spiral aloe one of the most photographed, thanks to its mesmerizing spiral shape. Some botanists theorize that organisms grow in spiral shapes because it ensures the most exposure to light and requires the least amount of energy to form the repeating pattern. The solitary rosettes may grow to 2 feet across but only 1 foot tall, making an interesting specimen for a rock garden, green roof, or poolside container garden.

Aloe hereroensis is a chameleon, appearing silvery gray, pale green, or even pinkish, depending on the light exposure and irrigation it receives. The small spines that grow on leaf edges are sharp, so use gloves when planting or weeding around this aloe. It's as tough as it looks and will bounce back from temperatures as low as 25 degrees.

Soap Aloe (Aloe maculata)
ffaber53 / Getty Images
Aloe maculata has sharp spines on each leaf that rival any cactus, but it rarely needs tending other than clipping off spent blossoms. So hands-on maintenance isn't necessary to grow this sturdy plant. Natives in South Africa have used the sap from this aloe type as a soap, but harvesting leaves from your specimen isn't advised, as the plants are very slow-growing and may not recover their symmetry afterward.

Aloe marlothii is a large plant best suited to growing outdoors in an arid, frost-free climate. Over time, the aloe forms a trunk-like stem surrounded by old leaves (similar to the growth pattern of some palms). The spiny leaves are quite imposing, and a mature specimen in flower with red and yellow blooms during the winter makes for quite an eye-catching sight.

The more sun Aloe vanbalenii receives, the more fantastic red coloration this specimen will reveal. Leaves may curve to the point of resembling tentacles. A unique feature of Van Balen's aloe is the spicy smell the leaves emit when you crush them. Grow this large aloe type among landscaping or in a conservatory.

Krantz aloe thrives in rocky landscapes, which mimic its native environment of rocky ridges and cliffs. Aloe arborescens boasts striking red and orange flowers and branches that fan out like the arms of a candelabra, hence its nickname, candelabra aloe. Krantz aloe is one of the few aloes that similar to aloe vera, has medicinal properties in its thick leaves.

Reaching 30 feet into the air, climbing aloe earns its nickname because of its warp climbing and growing speed. With full sun, Aloiampelos ciliaris can shoot into the air, leaving vibrant orange and red flowers trailing along its path. For those who want to plant climbing aloe in their own yard, it's a low maintenance, easy to grow plant.

Coral Aloe (Aloe Striata)

Hardy and drought-tolerant, the low-growing coral aloe grows smooth leaves and coral red blooms that attract hummingbirds and insects. Aloe Striata is a favorite in xeriscape landscaping, and it can stand up to extreme weather, including frost. However, you may want to bring it in over long, cold winter stretches.

Jewel Aloe (Aloe distans)

Jewel aloe may only reach 5 inches tall, but that doesn't mean it's a petite plant. This popular ground cover can reach 5 feet across, filling a space with waxy, triangular leaves. Aloe distans' leaves have an intimidating look with jagged teeth, but their foliage attracts pollinators with its vibrant color.

Tiger aloe (Gonialoe variegata)

The eye-catching striped leaves of tiger aloe give it its catchy name. And it's those bold, graphic leaves, in addition to its low maintenance nature, that make Gonialoe variegata a popular choice for an indoor house plant. You can even keep it potted outdoors during the warmer months, then bring it in when it gets colder. It boasts orange and pink flowers from July to September.

Aloe Ferox is another medicinal aloe, but this one has a bitter aloe that is used as a laxative. Cape aloe, named after the region in which its native, grows nearly 10 feet into the sky, with tubular, multi-branched flowers that reach up to 4 feet above the highest leaves. Similar to other aloes, there are spikes along its lance-shaped leaves.

When you think of Aloe, chances are the first thing that comes to mind is Aloe vera. However, there are over 600 species ranging in size from a few inches to 20-foot aloe trees. These evergreen succulents have fleshy leaves and are native to arid, semi-arid, and tropical regions. Their sensitivity to frost limits garden usage to frost-free zones for the most part, but many can also be grown in containers and moved to a warmer location over winter. Most Aloe bloom in winter, attracting hummingbirds to their bright tubular flowers when little else is available.

ALOE VERA
TYPES OF ALOE PLANTS
DESIGN TIPS FOR USING ALOES
ALOE VS. AGAVE
ALOE BASICS
Zones:Most aloes can be grown outdoors in Zones 9-11. There are a few varieties that are hardy to Zone 7 or 8, and some heat-tolerant to Zone 12. The ideal growing temperature for most aloes is 40° to 90°F, but many will do fine with brief periods as low as 25° or up to 100°F.
Height/Spread:Varieties range from small plants 2 to 4 inches tall and wide to tree types at 20 feet or more.
Exposure:Aloes need full sun of at least 6 hours a day. Many varieties will benefit from partial afternoon shade, especially in desert climates. Full sun encourages flowering, as well as boosts the red and orange tones in the leaves. Ample sunshine also makes them less susceptible to pests, diseases, and rot from overwatering.
Bloom time:Most Aloe bloom mid-winter; some in summer and late autumn. However, you can find species that bloom just about any time of year. If year-round temperatures are mild enough, some may bloom periodically throughout the year.
Color and characteristics:Aloe have tubular flowers that bloom in clusters on tall stalks that shoot up above the foliage. Flowers are mainly shades of orange, red or yellow, and occasionally cream, pink, green or white. Their sword-shaped leaves can be straight or curved and have serrated edges, or “teeth.” When stressed by cold, drought, too much sun, or even extremely poor soil, leaves may develop red or orange coloring along the edges or throughout.

ALOE ALTERNATIVE:
Love the dramatic blooms of aloe, but can’t grow them? Get this look with red hot poker, a perennial with grass-like foliage and tall yellow, red or orange spiky flowers. The Pyromania™ series will bring a unique drama to your landscape.
Zones: 5 - 9
Blooms: Summer
Exposure: Full sun
Height: 24 to 54 inches
PLANTING ALOE
When to plant:Spring is the best time to transplant aloes because they do most of their growing in the summer.
Where to plant:Plant aloes where they will receive at least 6 hours of sunlight per day and in well-drained soil to prevent rot. If grown in a borderline zone where temperatures may dip, plant them in a location that provides some insulation and protection from cold air or wind. Small and medium varieties do well in containers with appropriate drainage.
How to plant:When transplanting aloe, dig the planting hole wide, but not too deep. Remove the plant from the container, keeping the root ball intact. Place the plant in the hole so that the base of the plant is at ground level, and spread the roots out. Backfill the hole with soil and water to settle the plant in. Stake larger plants as needed.
ALOE PLANT CARE

Pruning/Maintenance:Once established, aloes require very little care. If a tree-like species develops a “petticoat” of old foliage, it’s best to leave the drooping leaves as they protect the trunk from temperature extremes and sunburn.
Soil:Aloes aren’t particular about the type of soil; however, it must drain well. Like all succulents, aloes store water in their leaves. Plants will rot in soil that has excess moisture that they don’t need.
How often to water aloe:Water occasionally, especially newly planted aloes and those in extremely hot, dry locations. In many locations, established aloes may not require any supplemental water at all.
How to propagate aloe:Offsets that grow at the base of the plant can be separated in late spring or early summer. Re-plant them in a standard cactus potting mix.
Diseases and pests:Aloes can be susceptible to mealybugs, scale, and various forms of rot — usually caused by overwatering and inadequate drainage. Deer tend to stay away from aloe due to the serrated leaf edges and thorns or spines on some; although, no plant is completely safe if deer are hungry enough.
Other:For occasional overnight freezes, cover outdoor aloes with a large plastic container or plant blanket. If the cold snap is longer, a thick layer of mulch or straw will help protect the roots.
ALOE VERA
Often grown as an easy-care houseplant, Aloe vera grows well in sandy, well-drained soil such as a cactus potting mix. Water your Aloe vera plant deeply, but not too often, allowing the soil to completely dry to a depth of 1 to 2 inches between watering. They prefer tight quarters and keeping them slightly root bound will help promote blooming when grown indoors.
Toxicity:Aloe vera plants are widely used for health and medicinal purposes; however, there are parts of the plant that can be toxic. Just inside the outer skin of the leaves, is a layer of yellow juice (aloin) that can cause skin irritation to people or animals with latex allergies and serious digestive issues if ingested. Aloe vera plants should always be kept out of the reach of children and pets.
How to cut an aloe vera plant:In order to safely use the beneficial gel inside the aloe leaves, cut the leaf from the base of the plant and slice it in half lengthwise (like a fillet). Scrape out the clear gel in the center of the leaf, leaving behind the layer close to the skin. Don’t cut the plant leaves and squeeze the gel out, as you’ll get some of the aloin with it. Aloe leaves can also be placed vertically to drain out the aloin after cutting.

DESIGN TIPS FOR USING ALOES
Aloes can be used as a solitary focal point or massed in the landscape in Mediterranean, succulent, or drought-tolerant gardens.
Small and medium aloes are perfect for mixed containers or rock gardens.
In colder zones, plant medium to large aloes in containers so they can be moved to a warmer area in winter.
Plant with companion plants like succulent ground covers, agaves, prickly pear, spurge and other waterwise or drought-tolerant plants.
HOW TO TELL AN ALOE FROM AN AGAVE
Aloes and agaves look very similar, making them difficult to tell apart; however, there are a few differences. Aloe leaves have fleshy centers and Agave are more fibrous. Agaves have sharp teeth along their edges with a line of demarcation. The teeth on Aloe leaves are actually extensions of the leaf, without any delineation. Mature Aloe plants bloom every year, while most Agave bloom only once, later in their lives, and then slowly die. Their care is very similar, so if you do get them confused, chances are you won’t kill them.

What is aloe vera?
Aloe vera is a plant used as a traditional medicine for centuries. In fact, stone carvings show it was popular in ancient Egypt.1
It’s still widely used in cosmetics, skincare, dietary supplements, and herbal medicine.
The two parts of the aloe vera plant used herbally are:2
the clear gel found inside the leaves
the yellow substance called latex, is found just under the plant’s skin
Aloe vera is available as tablets, capsules, gels, and ointments. You can also sometimes find it in health drinks, as an ingredient in cosmetic products and in hand sanitisers.
Eating aloe vera
Yes – the firm, clear gel inside aloe vera leaves is edible.
Be careful if eating aloe vera, though.
The yellow latex layer surrounding the gel (underneath the tough green skin of the leaves) acts as a powerful laxative and can cause cramping and other gastrointestinal symptoms if ingested.3
If you’re eating aloe vera straight from a plant, make sure it’s an edible variety of aloe vera.
Aloe vera barbadensis Miller is the most common variety considered edible. Avoid the aloe vera var. Chinensis, which isn’t edible.4
There are some benefits of eating aloe vera, too, from aiding digestion, helping to keep your teeth clean and providing your body with essential nutrients it needs.
But, generally, these benefits have yet to be studied in depth.4
Summary
Aloe vera is made up of clear, firm gel, which is surrounded by latex and tough green leaves
The Aloe vera barbadensis Miller plant is edible – but avoid the latex

Despite its long-term traditional use, few robust clinical studies have looked at aloe vera.
But so far, evidence suggests it may have a role to play in the following areas:
Aloe vera for psoriasis
Some people with this skin condition – characterised by inflamed, itchy, scaly patches, which can sometimes crack and bleed – use aloe gel to soothe symptoms.
The evidence is mixed, but research does suggest that aloe vera may help ease certain symptoms of psoriasis alongside other management techniques.
For example, its wound-healing properties can mean it helps cracked skin repair itself, while glucomannan encourages the production of collagen, which may help prevent new patches from forming.5

Aloe vera for constipation
Traditionally, the latex in aloe vera, when taken orally, has a long history as a remedy for constipation. Its benefits are mainly due to a type of natural laxative found in aloe’s latex called aloin.
Several studies have supported aloe latex’s effectiveness for treating constipation, although one of these positive studies looked at aloe in combination with celandine and psyllium rather than on its own.6

Aloe vera for burns
Aloe vera may be beneficial for soothing burns, according to a 2015 review of research published in BioMed Research International.
Aloe’s secret? The gel contains a compound called glucomannan, which boosts the formation of new skin cells and collagen production.7
Whether it's aloe vera for sunburn or for minor burns, pure aloe vera has cooling properties and acts as an excellent natural moisturiser to help soften and soothe the skin.
That’s why you’ll often find aloe vera listed as an ingredient in your after sun.
Aloe vera has also been shown to reduce the time it takes for minor burns to heal. One study found that aloe vera application could shorten burn healing time by up to nine days.8
Aloe vera as an antimicrobial
Aloe vera holds antimicrobial properties and has been used in clinical settings to decontaminate new dental equipment.9
This cleansing activity means aloe vera is also suitable for dabbing on minor skin issues to help safeguard against bacterial infection.10
Aloe vera for insect bites
The cooling effect of aloe vera on the skin makes it ideal for stopping the itching of insect bites.
One study found that applying a herbal gel containing aloe vera was as effective as hydrocortisone (a topical steroid) at calming down a fresh mosquito bite.11
Furthermore, aloe vera can prevent the production of histamine that causes itching and irritation.12

Aloe vera as an antioxidant
Aloe vera contains polyphenols – powerful plant antioxidant compounds – as well as other antioxidants, including vitamin A (beta-carotene) and vitamins C and E.13
Antioxidants help prevent disease and premature ageing by neutralising free radicals - harmful molecules that cause cell damage.
Aloe vera for IBS
Aloe vera has been traditionally taken as a remedy for gastrointestinal disorders, including irritable bowel syndrome (IBS).
While medical professionals do not yet acknowledge it, there have been some studies that show its promise in this area.
For example, daily aloe vera supplementation has been linked to improving ulcerative colitis symptoms, which causes inflammation in the colon.14
A review of studies in 2018 concluded that aloe vera is effective and safe in treating irritable bowel syndrome (IBS) compared to a placebo.
Aloe vera for blemish-prone skin
Aloe vera’s astringent properties make it a good choice for helping to manage blemish-prone skin – which is frequently caused by blocked hair follicles, excess sebum, and dirt on the skin.15
The zinc in aloe vera acts as an astringent to tighten pores, while the amino acids in aloe vera soften hardened skin cells and encourage them to slough off and renew.16
Further, aloe vera has been shown to increase the effectiveness of blemish-prone skin care tretinoin when used alongside it.17
Aloe vera for weight loss
Drinking aloe vera juice has been linked with weight loss.
The fat-reducing properties of aloe vera juice may be due to the presence of various phytochemicals such as flavonoids and polyphenols.
More research is needed, but some studies have indicated that aloe vera gel may help keep body weight down by stimulating the burning of energy by the body.18,19

Wondering what you can do with aloe vera? Here are 8 different ways to use aloe vera.
8 aloe vera uses
Aloe vera for hair
Aloe vera applied daily to your scalp might help keep your scalp clear and fresh by helping to slough off dead skin cells and open pores.
The topical application of herbal preparations containing fresh aloe vera has been shown to boost hair growth in one study.20
Aloe vera for face
Aloe vera can have some great benefits for your skin!
Its hydrating activity and soothing qualities make aloe vera gel ideal for adding to a DIY face mask.
Simply add a tablespoon of aloe vera gel to a skin-loving mixture of mashed avocado, honey, apple cider vinegar or plain yoghurt and apply to your face. Leave for around 10 minutes and rinse gently.
Aloe vera colon cleanse
Consuming aloe vera in juice, powder or gel form can help add fibrous bulk to your stool and encourage a swifter passage through your digestive tract.
Further, aloe is thought to help reduce inflammation in the colon.21
Aloe vera for sunburn
The discomfort of mild sunburn can be relieved by applying aloe vera gel directly to the skin like an after-sun. In fact, you’ll probably see aloe vera listed as an ingredient in some of your favourite after-sun products on the shelf!
We recommend keeping your tube of aloe vera gel in the fridge for a boosted cooling effect.22
Aloe vera for eczema
Aloe vera’s soothing and anti-inflammatory properties make it a good choice for applying to itchy skin affected by eczema.23
Aloe vera for skin soothing
Aloe vera helps your skin repair itself by stimulating skin cell regrowth.24
This is thought to be down to the glucomannan it contains, which helps the skin produce collagen.25
Keep a tube of aloe vera gel handy in your home for whenever you or your family experience a minor skin complaint. Just dab a little aloe vera gel onto spots, stings, scrapes, minor cuts, and other skin concerns.
Aloe vera for the hands
Aloe vera can help hands which have been ravaged by exposure to external irritants such as hand sanitiser.
One study examined the effects of a treatment which involved wearing an aloe vera gel glove on one hand daily for 30 days.
The gloved hand saw an improvement in skin integrity and a reduction in dryness compared to the non-gloved hand.26
Aloe vera for wrinkles
The topical application of aloe vera can boost skin moisture. But there’s also evidence that dietary supplementation with aloe vera can help improve skin elasticity and reduce the appearance of fine lines and wrinkles.
The study was based on 30 women taking either 1200mg or 3600mg of aloe vera gel daily for 90 days.27

Wondering how much aloe vera you should be taking? Keep reading to find out.
How much aloe vera is safe to take?
As a cream, gel, or ointment applied topically, aloe vera is safe to use as needed so long as you aren’t experiencing a skin reaction.
For oral use, strengths and preparations vary greatly, so always read the label carefully and follow directions for oral use.
Aloe vera side effects
Gastrointestinal upset
Due to aloe vera’s laxative effects, it is best to start with a small amount when taken orally, as it can cause diarrhoea and stomach cramps in some people.
Irritated skin
Although aloe vera soothes skin for most people, some can experience itching, burning, and skin irritation.28
Liver problems
When taken orally, excessive aloe vera intake for a prolonged period has been linked to toxic hepatitis in rare cases.29
Is aloe vera suitable for everyone?
Avoid taking aloe vera orally if you have diabetes – aloe vera can lower blood glucose levels.30
If you’re taking any medication orally, remember aloe vera’s a laxative. Diarrhoea can reduce the absorption of the medication.
Children under 12 and pregnant or breastfeeding women should not take aloe vera but can use aloe vera topically.
People with digestive disorders, such as Crohn’s, should also avoid drinking any aloe preparations.31
You may have an aloe vera allergy if you’re allergic to plants of the Liliaceae family – including tulip and lily flowers.
It’s essential to be aware that aloe vera plants may be toxic to cats, dogs, and other pets.
The final say
Aloe vera side effects can include gastrointestinal upset, irritated skin and, in rare cases, liver problems
Aloe vera isn’t suitable for oral use by people with diabetes or digestive disorders
Children, pregnant women, and breastfeeding women shouldn’t ingest aloe vera
