Giant knotweed is an herbaceous perennial, strongly rhizomatous, growing over 12 feet tall. Resveratrol is the main ingredients.
Resveratrol has several activities that may accout for its possible cardio protective action. These include inhibition of the oxidation of low-density lipoprotein (LDL), inhibition of smooth muscle cell proliferation and inhibition of platelet aggregation. Resveratrol has also been found to reduce the synthesis of lipids in rat liver and to inhibit the production of proatherogenic eicosanoids by human platelets and neutrophils.

Trans-Resveratrol is a polyphenol found in a variety of plants. Resveratrol has been examined for its potential therapeutic benefit in the treatment or prevention of cancer, heart disease, neurodegeneration, and inflammation. Trans-Resveratrol is generally produced by isolating it from extracts of grape skin or from the plant Polygonum cuspidatum. It is sold as a dietary supplement. Resveratrol possesses diverse biochemical and physiological actions, which include estrogenic, antiplatelet, and anti-inflammatory properties.
Resveratrol is a true miracle drug, which helps to prevent diabetes, obesity, and metabolic syndrome. Again, resveratrol was found to increase the activity of anti-aging gene SIRT1 activity. Resveratrol-mediated activation of life-extending genes in human cells may open a new horizon of resveratrol research.
An overwhelming amount of literature now emphasizes the antioxidant role of resveratrol and its beneficial effects on diseases due to oxidative stress. Resveratrol has been shown to exert antioxidant effects via modulating the production of ROS and nitric oxide (NO) from vascular endothelium, thus exhibiting its cardiopulmonary-protective function .
