Latin name: Polygonum cuspidatum
Chinese name: Hu Zhang
Polygonum most grows in ravine, by the river and in shady-warm places under trees,
mainly distributed in the south of Changjiang River, Shan’xi, Henan and Shandong
provinces in China.The protophyte of Polygonum is regarded as rhizome and root of
Polygonum cuspidatum Sieb. et Zucc., perennial herbaceous, being one of the Chinese
medicinal herbs most in use in ancient China.

Efficacy & mechanism to anti-cancer and to strengthen immunity
Resveratrol in Polygonum is the major active ingredient, which has effect to anti-cancer
and to strengthen immunity through research.Resveratrol has very strong effect to clear
oxidant free radical, along with inhibiting the damage and mutation to the body caused by
free radical. The research to cytology based on in vitro cancer cell proved that Resveratrol
could inhibit the breeding of various cancer cells. The proliferation of cancer cells is due
to secretion of ROS by stimulus and a certain quantity of O-2 and H2O2. Another
research proved that Resveratrol has very strong inhibition to the total ROS
self-secreted by cancer cells. It inhibits the density of O-2 , stops the changes
of cancer cells from S to G2, thus strongly inhibiting the breeding of cancer cells.
Resveratrol may strengthen the immunity. It can also recover the inhibited characteristic
of cells in the burnt rat, with effective power to the reactive ability of damagedantigen
singal, to breeding ability, to synthetic ability of white blood cell medium Ⅱ and to
synthetic ability of antibody through lymph cell.
