Summary of Aloe vera

Primary information, health benefits, side effects, usage, and other important details

Aloe vera is a herb traditionally used to ease digestion as a folk remedy, and to alleviate pain from burns when used topically. It has recently gained popularity as an anti-obesity agent.

Preliminary studies show benefit with aloe vera in controlling weight, but the mechanisms do not seem as potent as other anti-obesity supplements. Aloe vera is also a generally healthy compound, but has been implicated in multiple cases of liver problems (which are not too common, although resurgent) and has a lower toxicity threshold than other herbal supplements.
