The varieties of sarsaparilla used in medicine are obtained from the dried root of Smilax officinalis and other varieties of smilax. The drug contains three glucosides: parillin, saponin, and sarsaponin.

Sarsaparilla is widely used, yet no definite physiological actions can be claimed for it. Whatever value it may have is as an alterative. The syrup is sometimes used to disguise the taste of potassium iodide.
