Giant knotweed rhizome is the dry rhizome and root of polygonum cuspidatum Sieb. et Zucc. Harvest at spring and autumn every year, and remove the fibrous root, make it clean, and then cut it into short pieces or junks, open-air drying.
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.
