Get StartedDosing
The below doses are based on scientific research, publications, traditional use, or expert opinion. Many herbs and supplements have not been thoroughly tested, and safety and effectiveness may not be proven. Brands may be made differently, with variable ingredients, even within the same brand. The below doses may not apply to all products. You should read product labels, and discuss doses with a qualified healthcare provider before starting therapy.
Adults (18 years and older)
Pure Aloe vera gel is often used liberally on the skin three to four times per day for the treatment of sunburn and other minor burns. Creams and lotions are also available. There are no reports that using aloe on the skin causes absorption of chemicals into the body that may cause significant side effects. Skin products are available that contain aloe alone or aloe combined with other active ingredients.
The dose often recommended for constipation is the minimum amount to maintain a soft stool, typically 0.04-0.17 gram of dried juice (corresponds to 10-30 milligrams hydroxyanthraquinones) by mouth. As an alternative, in combination with celandine (300 milligrams) and psyllium (50 milligrams), 150 milligrams of the dried juice per day of aloe has been found effective as a laxative in research.
Cases of death have been associated with Aloe vera injections under unclear circumstances. Injected use is not recommended due to a lack of safety data.
Other uses of aloe from scientific studies include the treatment of genital herpes (cream applied to lesions for five consecutive days per week for up to two weeks) and psoriasis (cream applied to skin three times per day for five consecutive days per week for up to four weeks).
Children (younger than 18 years)
Topical (skin) use of aloe gel in children is common and appears to be well tolerated. However a dermatologist and pharmacist should be consulted before starting therapy. Aloe taken by mouth has not been studied in children and theoretically may have harmful effects, such as lowering blood sugar levels. Therefore, it is not recommended.
