Botanical name: Knoxia spp. Family: Rubiaceae
Knoxia is a type of plant related to the euphorbia plant. Although it is native to Japan, it now grows throughout Asia. In China, it is grown mainly in the Shanxi, Shandong, Jiangsu, Sichuan and Guangxi provinces, and harvested twice a year. In traditional Chinese medicine, knoxia root is considered bitter, pungent and cold, and is associated with the Lung, Kidney and Large Intestine meridians. Its functions are to reduce swelling and resolve masses, and to arrest water retention. Knoxia root is used to treat edema and fluid retention on the face and body, and to treat surface infections on the skin. Fresh herb is used for external applications.
