  • What's Polygonum Cuspidatum Extract  

Resveratrol is a naturally occurring phytoalexine found in medicinal plants. Resveratrol is an active component extracted from Huzhang (Polygonum cuspidatum) in China. It is an antioxidant phenol and a potent vasodilator that inhibits serum triglyceride synthesis, lipid peroxidation, and platelet aggregation. It is extensively used for treatment of blood vessel disease such as atherosclerosis and hyperlipidemia. In addition, it has anti-virus and anti-inflammatory activity, can treat acute microbial infections and viral hepatitis, ect.


Polygonum cuspidatum is important concentrated sources of resveratrol and its glucoside piceid, replacing grape byproducts. Many large supplement sources of resveratrol now use Polygonum cuspidatum and use its scientific name in the supplement labels. The plant is useful because of its year-round growth and robustness in different climates.
