Smilax zeylanica L., belonging to the monocotyledon family Smilacaceae, is a dioecious climbing shrub with woody stem. The plant is used as a substitute for Sarsaparilla. In this review, we present updated information on the ethnobotanical uses, phytochemistry and pharmacological activities shown by S. zeylanica by referring standard flora, journal articles and various search engines. Whole plant or certain parts of the plant (leaf, root, rhizome, fruit and stem) are used ethnobotanically in several countries for several purposes such as fodder, vegetable and in the treatment of diseases like skin diseases, piles, dysentery, venereal diseases, rheumatism, toothache, arthritis, and urinary complaints.
