Sarsaparilla

Sarsaparilla is a soft drink originally made from the vine Smilax ornata (also called 'sarsaparilla') or other species of Smilax such as Smilax officinalis. In most Southeast Asian countries, it is known by the common name sarsi, and the trademarks Sarsi and Sarsae. It is similar in flavor to root beer. In the US, sarsaparilla is traditionally made with birch oil rather than the tropical plant. Smilax ornata, a perennial trailing vine with prickly stems that is native to Mexico and Central America, is often used as the basis for the soft drink sarsaparilla. Common names include sarsaparilla, Honduran sarsaparilla, and Jamaican sarsaparilla. It is known in Spanish as zarzaparrilla, which is derived from the words zarza meaning "bramble" (from preroman sarza), and parrilla, meaning "little grape vine".
