Resveratrol is an active component extracted from Polygonum cuspidatum root from China,other natural source including grape skin,peanut,etc.

As early as the 1920's Dr. Johanna Brandt wrote a book proclaiming that grapes cured her of cancer.

Resveratrol Introduction:
Resveratrol (3,4',5-trihydroxystilbene) belongs to a class of polyphenolic compounds called stilbenes. Some types of plants produce resveratrol and other stilbenes in response to stress, injury, fungal infection, and ultraviolet (UV) radiation.

Resveratrol is a fat-soluble compound that occurs in a trans and a cis configuration. Both cis- and trans-resveratrol also occur as glucosides (bound to a glucose molecule). Resveratrol-3-O-beta-glucoside is also called piceid. Scientists became interested in exploring potential health benefits of resveratrol in 1992 when its presence was first reported in red wine, leading to speculation that resveratrol might help explain the French Paradox.
