The usage of aloe vera can be traced back to 6,000 years in early Egypt, where the plant was depicted on stone carvings. Known as the “plant of immortality,” aloe was presented as a burial gift to deceased pharaohs.
What Aloe Vera Is Used For
- Traditionally, aloe was used topically to heal wounds and for various skin conditions and orally as a laxative.
- Today, people take aloe orally to also treat a variety of conditions, including diabetes, asthma, epilepsy, and osteoarthritis. It is used topically to treat osteoarthritis, burns, sunburns, and psoriasis.
- Aloe vera gel is used in hundreds of skin products, including lotions and sunblocks.

- Aloe latex contains strong laxative compounds. Products made with various components of aloe (aloin, aloe-emodin, and barbaloin) were
- Early studies show that topical aloe gel may help heal burns and abrasions. But one study showed that aloe gel inhibits the healing of deep surgical wounds. Aloe gel has not been shown to prevent burns from radiation therapy.
However, there is not enough scientific evidence to support any other uses of aloe vera.
Side Effects And Cautions
Use of topical aloe vera is not associated with significant side effects.
A 2-year National Toxicology Program (NTP) study on oral consumption of non-decolorized whole leaf extract of aloe vera found clear evidence of carcinogenic activity in male and female rats, based on tumors of the large intestine. According to the NTP, from what is known right now, there is nothing that would lead them to believe that these findings are not relevant to humans. However, more information, including how individuals use different
- Abdominal cramps and diarrhea have been reported with oral use of aloe vera.
- Diarrhea, caused by the laxative effect of oral aloe vera, can decrease the absorption of many drugs.
- People with diabetes who use glucose-lowering medication should be cautious if also taking aloe orally because preliminary studies suggest that aloe may lower blood glucose levels.
- There have been a few case reports of acute hepatitis from aloe vera taken orally. However, the evidence is not definitive.
