BioPure Smilax extract features all natural Smilax. Smilax genera is classified within the Liliaceae family and contains over three hundred species. Most are thorny, climbing vines with reddish berries, found growing in tropical climates of the world including South America, Asia, and the Caribbean.
Decoctions made from the fibrous tubers and rhizomes of Smilax glabra have been used for hundreds of years in traditional Chinese medicine for a variety of purposes that include hormone, immune system and liver support, and as a general health tonic.*

Scientific research has identified numerous potentially beneficial bioactive substances in the rhizomes of Smilax glabra. Astilbin and Smilaxin are among the most well-known. Astilbin, a flavonoid compound, demonstrated potent antioxidant activity and exerted a protective effect on the kidneys.* The protein Smilaxin exhibited immunostimulatory and antiproliferative abilities.* Several other proteins isolated from S. glabra rhizomes show support of immune system capabilities.* For instance, SGRP1, identified in 2017, activated macrophages and promoted phagocytosis.*

Due to the wide distribution and many species of Smilax, the plant may be referred to by many names including zarzaparilla, Smilacis glabrae, Tu Fu Ling, Chinaroot, and sarsaparilla. It is also sometimes confused with sassafras, which comes from the volatile oils of the bark of a tree in the Laurel family, that was used to flavor Root Beer. BioPure uses only the extract of pure Smilax glabra, the species of herb used historically in traditional Chinese medicine.

BioPure’s Smilax glabra extract is available individually as a 2 fluid ounce liquid tincture in a 55% organic corn alcohol solution. It is also available as one of five herbal extracts combined in our Quintessence formula.
