Keypoints
• Because of its popularity with consumers, it is important to
determine the efficacy and safety of aloe vera products.
• Only 10 controlled clinical trials of aloe vera exist (for various
indications).
• These trials suggest that oral aloe vera might be valuable for
lowering cholesterol or reducing glucose levels. Topical aloe
vera could be effective for genital herpes or psoriasis.
• However, for none of these indications are the existing data
sufficient to draw firm conclusions.
