Smilax glabra is used in Chinese herbology. It is also a key ingredient in the Chinese medical dessert guīlínggāo, which makes use of its property to set certain kinds of jelly.

Chemical composition

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]

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

gollark: AMD cards tend to have lots of VRAM and compute. Sadly they don't make Radeon 7s any more, that'd be perfect.
