Huzhang ("tiger cane") or giant knotweed is an east Asian species (Polygonum cuspidatum), belonging to the Polygonaceae family. Resveratrol is a naturally occurring phytoalexin produced by some higher plants in response to injury or fungal infection. Resveratrol may also have alexin-like activity for humans. Epidemiological, in vitro and animal studies suggest that a high resveretrol intake is associated with a reduced incidence of cardiovascular disease, and a reduced risk for cancer.
