Chuan Niu Xi Tincture & Alcohol-Free Extract

Chuan Niu Xi (Cyathula officinalis), the Sichuan ox-knee, is a perennial of the amaranth family, Amaranthaceae, native to the mountains of Sichuan, Yunnan, and Guizhou in southwestern China, where it is grown at 1,500 meters and above. It stands 50 to 100 centimeters with angular, hairy stems whose swollen joints suggested the Chinese name, opposite, elliptic, pointed leaves, and dense, round, greenish-white flower heads in the upper leaf axils that harden into bristly burrs. The taproot is long and cylindrical, 30 to 60 centimeters, grey-brown and finely wrinkled outside, yellowish inside, and tastes sweet then slightly bitter. We extract the dried root.
