How much do we know about Aloe vera

Aloe latex contains strong laxative compounds. Products made with aloe were at one time regulated by the U.S. Food and Drug Administration (FDA) as over-the-counter (OTC) laxatives. In 2002, the FDA required that all OTC aloe laxative products be removed from the U.S. market or reformulated because the companies that manufactured them did not provide the safety data necessary for continued approval.
There’s some evidence that the topical use of aloe products might be helpful for symptoms of certain conditions such as psoriasis and certain rashes.
There’s not enough high-quality scientific evidence to show whether topical use of aloe helps to heal wounds.
There’s not enough scientific evidence to support aloe vera for any of its other uses.
