Resveratrol (trans-resveratrol) is a phytoalexin produced naturally by several plants when under attack by pathogens such as bacteria or fungi. Resveratrol has also been produced by chemical synthesis and is sold as a nutritional supplement derived primarily from Japanese knotweed (Polygonum).
In mouse and rat experiments, anti-cancer, anti-inflammatory, blood-sugar-lowering and other beneficial cardiovascular effects of resveratrol have been reported. Most of these results have yet to be replicated in humans.
In the only positive human trial, extremely high doses (3–5 g) of resveratrol in a proprietary formulation have been necessary to significantly lower blood sugar. Resveratrol is found in the skin of red grapes and is a constituent of red wine, but apparently not in sufficient amounts to explain the French paradox. Experiments have shown that resveratrol treatment extended the life of fruit flies, nematode worms and short-lived fish but it did not increase the life span of mice.

Polygonum Cuspidatum, also known as Japanese knotweed, is a large, robust perennial that spreads by long creeping rhizomes to form dense thickets. The stems are stout, cane-like, reddish-brown, 4 to 9 feet tall. The plants die back at the end of the growing season. The stem nodes are swollen and surrounded by thin papery sheaths. The leaves are short-petioled, 2 to 6 inches long and about two-thirds as wide, egg-shaped and narrowed to a point at the tip. The flowers are small, creamy white to greenish white, and grow in showy plume-like, branched clusters from leaf axils near the ends of the stems. The fruit is 3-sided, black and shiny.
In China, the root was used medicinally to treat menstrual and postpartum difficulties. In recent years, the Chinese have been using huzhang in the treatment of burns and acute viral hepatitis with considerable success. Researchers have found that some of its chemical components have antibacterial, antiviral, liver protectant and antioxidant effects. The unique broad, traditional and modern properties which include detoxicant, antiburn, wound healing, astringent, antimicrobial and antioxidant, have been utilized in skin care cosmetics and environmental products. Its extracts are used in skin lotions, a ntifatigue, massage and cleansing creams as well as in an herbal disinfectant approved by the US EPA.
