S. glabra is a traditional medicine in Chinese herbology, whence it is also known as tufuling ({{lang|zh|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
Dihydro-flavonol glycosides (astilbin, neoastilbin, isoastilbin, neoisoastilbin, (2R, 3R)-taxifolin-3'-O-beta-D-pyranoglucoside) have been identified in the rhizome of Smilax glabra{{cite journal |vauthors=Yuan JZ, Dou DQ, Chen YJ, etal |title=[Studies on dihydroflavonol glycosides from rhizome of Smilax glabra] |language=zh |journal=Zhongguo Zhong Yao Za Zhi |volume=29 |issue=9 |pages=867–70 |date=September 2004 |pmid=15575206 }} as well as smitilbin, a flavanonol rhamnoside.[https://archive.today/20120908101540/http://www.pdfdownload.org/pdf2html/pdf2html.php?url=http://www.imm.ac.cn/journal/ccl/1306/130618-537-01-578-p2.pdf&images=no A Flavonol Glycoside from Smilax glabra, Ting Chen, Jian Xin Li, Yu Cai, Qiang Xu, Chinese Chemical Letters, Vol. 13, No 6, 2002, pages 537-538] Smiglabrone A and Smiglabrone B are phenylpropanoid-substituted epicatechins that have also been isolated from the root.{{Cite journal|last1=Gu|first1=Wan-Yi|last2=Li|first2=Na|last3=Leung|first3=Elaine|last4=Zhou|first4=Hua|last5=Luo|first5=Guo-An|last6=Liu|first6=Liang|last7=Wu|first7=Jian-Lin|date=2015-03-02|title=Metabolites Software-Assisted Flavonoid Hunting in Plants Using Ultra-High Performance Liquid Chromatography-Quadrupole-Time of Flight Mass Spectrometry|journal=Molecules|volume=20|issue=3|pages=3955–3971|doi=10.3390/molecules20033955|pmid=25738538|pmc=6272731|issn=1420-3049|doi-access=free}}

Use in traditional Chinese medicine
The root of S. glabra is used in traditional Chinese medicine (TCM) to treat dysentery, joint pain and colds.{{Cite journal|last1=Xu|first1=Shuo|last2=Shang|first2=Ming-Ying|last3=Liu|first3=Guang-Xue|last4=Xu|first4=Feng|last5=Wang|first5=Xuan|last6=Shou|first6=Cheng-Chao|last7=Cai|first7=Shao-Qing|date=May 2013|title=Chemical Constituents from the Rhizomes of Smilax glabra and Their Antimicrobial Activity|journal=Molecules|language=en|volume=18|issue=5|pages=5265–5287|doi=10.3390/molecules18055265|pmid=23698042|pmc=6270451|doi-access=free}} 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.{{Cite book|last=Wu|first=Jing-Nuan|title=An Illustrated Chinese Materia Medica|publisher=Oxford University Press|year=2005|isbn=9780195140170}}{{page needed|date=November 2020}}
