Achyranthes root, or known as Huai Niu Xi in Pinyin, is a common bulk Chinese herb. Being one of the most famous Four Huai medicines, it has a long history of cultivation and application in China. And it got its name because it was mainly produced in the historical Huai Qing Fu, where locates in today’s Jiaozuo in Henan province. In addition, the reason for the name of Niu Xi is twofold: the cylindrical Achyranthes have angular stem and enlarged node that looks like a bull’s knee, plus the healing power of this herb is just like the power of a bull. In TCM remedies it is commonly used as a medicine to unblock collaterals and activate blood. Clinically physicians love to prescribe it for the treatment of a variety of arthritis, osteoproliferation, cardiovascular and cerebrovascular diseases (including coronary heart disease, cerebral thrombosis, and cerebral arteriosclerosis), and gynecological diseases (including emmeniopathy, leukorrheal diseases, and various antenatal and postpartum illness).
