S. glabra is a traditional medicine in Chinese herbology, whence it is also known as tufuling (土茯苓) or chinaroot, china-root, and china root (a name it shares with the related S. china). Chinaroot is a key ingredient in the Chinese medical dessert guilinggao, which uses its ability to set certain kinds of jelly.

Chemical composition

edit

Dihydro-flavonol glycosides (astilbin, neoastilbin, isoastilbin, neoisoastilbin, (2R, 3R)-taxifolin-3'-O-beta-D-pyranoglucoside) have been identified in the rhizome of Smilax glabra[7] as well as smitilbin, a flavanonol rhamnoside.[8] Smiglabrone A and Smiglabrone B are phenylpropanoid-substituted epicatechins that have also been isolated from the root.[9][10]

Sarsasapogenin, a steroidal sapogenin, can also be found in S. glabra.[11]

Use in traditional Chinese medicine

edit

The root of S. glabra is used in traditional Chinese medicine (TCM) to treat dysentery, joint pain and colds.[9] S. glabra is grown in Southern China. The rhizome of the plant is collected and dried during all seasons for herbal use. The dried root is mixed with water and taken orally. It is believed to restore balance in the body in response to yin disease by removing dampness and toxicity.[12][page needed]
