Aloe vera is a succulent plant species of the genus Aloe. It is widely distributed, and is considered an invasive species in many regions of the world.
Orally ingested non-decolorized aloe vera leaf extract was listed by the California Office of Environmental Health Hazard Assessment among "chemicals known to the state to cause cancer or reproductive toxicity", possibly resulting from the anthraquinones. Since 2016, aloe vera whole leaf extract is classified as a possible human carcinogen (group 2B) by the International Agency for Research on Cancer. Use of aloe vera on the skin is generally not associated with significant side effects. Oral ingestion of aloe vera is potentially toxic, and may cause abdominal cramps and diarrhea which in turn can decrease the absorption of drugs.
Ingested aloe products may have adverse interactions with prescription drugs, such as those used to treat blood clots, diabetes, heart disease and potassium-lowering agents (such as digoxin), and diuretics, among others.
Also recorded as Aloe, Barbados Aloe, Barbados Aloes, Common Aloes, Curaçao aloe and Indian aloe.
