Qizhu Tang or referred to as (QZT)

QZT is a combination of 4 herbs Rhizome (Rhizoma Atractylodis Macrocephalae) Peria (Poria cocos is a mushroom) Notoginseng (Kadix Notoginseng a varity of ginseng that is reported to be much more powerful)

1. "A traditional Chinese herbal medicine, Qizhu Tang (QZT) was studied for its in vitro "test tube" antioxidant activity and the effect on cerebral oxidative damage after forebrain ischemia followed by reperfusion in rats. (ischemia is the constriction/restriction of blood vesels) ... Although some of the incomplete formulas showed as strong antioxidant activities as complete QZT in vitro, only the complete QZT formula was effective in preventing cerebral oxidative injury in rats, and other preparations showed limited activity in vivo.

2. "QZT consists of 4 herbal constituents (Rhizoma Atractylodis Macrocephalae, Poria cocos, Kadix Notoginseng, and Radix Astragali), each of the components and their combinations were examined in vitro for 1, 1-diphenyl-2-picrylhydrazyl (DPPH) and hydroxyl radical scavenging activities, and for the inhibition of thiobarbituric acid-reactive substances (TBARS) formation in rat liver homogenate. At the same time, their in vivo protective effect on cerebral ischemia-areperfusion injury was determined in rats... CONCLUSION: QZT formula is a good natural antioxidant having an effect."
