Aloe vera gel is widely known for its skin healing properties, but many people wonder if it is safe to ingest it directly. The clear gel inside aloe leaves is filled with nutrients like vitamins, antioxidants, minerals, and enzymes that provide several health benefits. While aloe gel has been used for centuries in folk medicine, current research also suggests that it may have a role in supporting digestive and immune health when consumed.
Is it safe to eat aloe vera gel straight from the plant?
Most experts agree that consuming pure aloe vera gel from the leaf of the plant is generally safe for most people. However, there are a few precautions to keep in mind:
- Aloe leaves contain latex, a bitter, yellow fluid located just under the plant’s skin. Ingesting this latex could potentially cause adverse effects like diarrhea and stomach cramping.
- Eating unprocessed aloe vera gel may also expose you to plant contaminants like bacteria, molds and pesticides if the plant wasn’t washed properly before use.
- Consuming large amounts of aloe vera gel could lead to diarrhea and electrolyte imbalances.
- Pregnant or nursing women should avoid consuming aloe vera gel until more research is done exploring its safety.
To reduce your risk of side effects, it’s best to start with small amounts of gel, about 2–4 tablespoons daily. Make sure to wash leaves thoroughly and remove the latex before eating. It’s also best to choose organic aloe plants to avoid pesticides.
How to prepare and eat aloe vera gel
Aloe leaves should be washed thoroughly before consuming the gel. Start by trimming off the base and tips of the leaves with a knife. Then, make a shallow, v-shaped cut along the length of each leaf to reveal the clear gel inside. Use a spoon to scoop out the gel, being careful not to take any of the bitter yellow latex located close to the leaf skin.
The gel can be eaten raw directly from the spoon, or it can be blended into smoothies, juices or yogurt. The gel will impart a mild, refreshing taste. Some people prefer to mix it with citrus juice or honey to mask the somewhat bitter flavor.
Here are some simple ways to eat aloe vera gel:
- Add 2 tablespoons to a fruit smoothie.
- Mix with lemon juice and use as a topping for fruit salads.
- Blend with other juices like apple, carrot or celery juice.
- Mix into Greek yogurt along with fruits and nuts.
- Add to oatmeal, yogurt parfaits or chia seed pudding.
- Use as a base for homemade popsicles.
Nutrition facts of raw aloe vera gel
Aloe vera gel is comprised of 99.5% water, while the remaining 0.5% contains a range of nutrients:
| Nutrient | Per 1 cup (approx. 240g) |
|---|---|
| Calories | 4 |
| Carbs | 1 gram |
| Protein | Less than 1 gram |
| Vitamin A | 2% DV |
| Vitamin C | 2% DV |
| Folate | 2% DV |
| Calcium | Less than 1% DV |
| Magnesium | 2% DV |
| Potassium | 2% DV |
Aloe vera gel also contains trace amounts of several vitamins like B12, choline and folic acid. It provides small amounts of antioxidants like beta-carotene and vitamin C.
Potential benefits of ingesting aloe vera gel
Research on the effects of ingesting aloe vera gel is limited. However, preliminary studies suggest it may provide the following benefits:
May aid digestion
Aloe vera contains compounds known as polysaccharides that may help protect the stomach lining and prevent digestive issues. Multiple rat studies show aloe vera juice can fight stomach ulcers and reduce acidity.
One study in rats with ulcerative colitis found that aloe vera extract decreased inflammation and helped heal intestinal lesions.
More human research is needed, but these results suggest aloe gel could potentially aid digestion and relieve inflammatory bowel diseases.
May boost immunity
The enzymes, vitamins, minerals and antioxidants in aloe vera gel may provide immune-boosting effects. One study found that aloe vera supplementation significantly increased the concentration of antioxidants in the blood.
Other test tube and animal research shows aloe gel may increase nitric oxide production, stimulate immune cells and reduce inflammation, indicating an immune-supporting role.
More studies are needed to confirm aloe’s ability to enhance immunity in humans when ingested.
May lower blood sugar levels
Aloe vera may also help lower blood sugar levels. In one study in diabetic rats, aloe vera extract decreased blood sugar by nearly 50% over 14 days of treatment.
Another 8-week study in humans with prediabetes found that drinking aloe vera juice twice daily significantly lowered fasting blood sugar and hemoglobin A1C levels compared to a placebo.
However, other research shows aloe may increase blood sugar levels at the same time. More research is needed to understand aloe vera’s effects on blood sugar.
Potential side effects of ingesting aloe vera gel
While eating pure aloe vera gel is likely safe for most people, some side effects have been reported:
- Diarrhea: Ingesting large amounts may act as a laxative, causing diarrhea as a side effect.
- Stomach pain and cramps: Consuming pure aloe latex has been linked to severe stomach pain, cramps and even kidney failure.
- Electrolyte imbalance: Long-term use can alter potassium levels, which can trigger heart complications.
- Drug interactions: Aloe may impact the effectiveness of medications like digoxin and metformin. Those on medication should consult a doctor before using.
- Allergic reactions: Some people are allergic to aloe vera. Discontinue if rash, hives or swelling develops.
Populations that should avoid aloe vera gel
While aloe vera gel is likely safe for most healthy adults, certain populations should avoid ingesting it:
- Pregnant and breastfeeding women: There is insufficient research on aloe vera’s safety during pregnancy and breastfeeding. It’s best to avoid ingesting it.
- Children: Do not give aloe vera juice or gel to children under age 12. The potential impacts on growth and development are unknown.
- Diabetics: Given aloe vera’s potential impact on blood sugar, people with diabetes should use caution and monitor blood sugar closely after ingesting it.
- Those with digestive diseases: Individuals with conditions like ulcerative colitis, Crohn’s disease or irritable bowel syndrome (IBS) should avoid aloe vera gel due to possible laxative effects.
- Kidney disease patients: The potassium levels in aloe vera gel may be problematic for people with kidney disorders.
- Surgery patients: Effects on blood sugar could interfere with blood glucose control during and after surgical procedures. Stop ingesting aloe at least 2 weeks before surgery.
How to choose an aloe vera product
While you can eat fresh aloe gel from the leaf, many people opt for prepared aloe vera juices, gels, capsules and powders as well.
When purchasing an aloe vera product, read the label closely to avoid adulterated products. The International Aloe Science Council provides a certification program for aloe products that meet purity standards.
Ideally, look for:
- Pure aloe vera inner leaf gel/juice as the first or only ingredient
- 100% aloe content
- Products made from organic, pesticide-free aloe vera plants
- Minimal processing for maximum retention of nutrients
- No added sugars, thickeners, artificial flavors or preservatives
You can also grow your own aloe vera plants to harvest fresh gel. Choose an aloe variety like Aloe Barbadensis Miller or Aloe Vera Barbadensis since they are the most researched.
How to store and preserve aloe vera gel
Fresh aloe gel is best consumed immediately after harvesting the leaves. However, it can be stored in the fridge for 2–3 weeks.
Ways to preserve aloe gel for longer shelf life include:
- Freezing: Freeze pure gel in ice cube trays or small containers.
- Dehydrating: Dehydrate slices of aloe vera gel in a food dehydrator or low oven until crispy.
- Canning: Boil prepared aloe vera juice in a water bath canner to kill bacteria. Can in sterilized jars.
Keep in mind processing and preservation techniques can degrade some of aloe vera’s active compounds. Minimally processed gel is best.
Conclusion
Eating pure aloe vera gel in moderation is likely safe and healthy for most people. It provides a range of nutrients and antioxidants that may benefit digestion, immunity, blood sugar and more.
However, drinking too much could lead to side effects like diarrhea, stomach pain and electrolyte imbalances. Certain groups like pregnant women, children and diabetics should also avoid ingesting aloe vera gel.
When buying prepared aloe gel products, choose organic, pure, minimally processed options. And be sure to wash fresh leaves thoroughly and remove the latex before eating raw aloe vera gel straight from the plant.
