What is Polydatin/Polygonin Giant Knotweed Extract?

Giant knotweed extract polygonum cuspidatum extract 98% polydatin
Giant knotweed extract polydatin is the glycoside of resveratrol originally isolated from the Chinese herb Polygonum cuspidatum. The polydatin has been shown to inhibit platelet aggregation and elevate the ratios of LDL-C/HDL-C and TC/HDL-C. Myocardial cell, white blood cell, vascular smooth muscle cell, and endothelial cell studies report that polydatin can inhibit ICAM-1 expression, elevate Ca2+, weaken white blood cell-endothelial cell adhesion, and activate KATP channels.
