Sarsaparilla (UK:/ˌsɑːrspəˈrɪlə/,US also/ˌsæspəˈrɪlə/sas-pə-RIL-ə)[1][2] is asoft drink originally made from the vineSmilax ornata (also called 'sarsaparilla') or other species ofSmilax such asSmilax officinalis.[3] In mostSoutheast Asian countries, it is known by the common namesarsi, and the trademarksSarsi andSarsae. It is similar in flavor toroot beer. In the US, sarsaparilla is traditionally made withbirch 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.[4] Common names include sarsaparilla, Honduran sarsaparilla, and Jamaican sarsaparilla.[5]
It is known inSpanish aszarzaparrilla, which is derived from the wordszarza meaning "bramble" (from preromansarza), andparrilla, meaning "little grape vine".[6][7][8][9][10]
Sarsaparilla was popular in the United States in the 19th century. According to advertisements forpatent medicines of the period, it was considered to be a remedy for skin and blood problems.[11][12]The Oxford Companion to American Food and Drink notes that it evokes images of "languidbelles and parchedcowboys".[13]
Sarsaparilla is sometimes considered to be a type ofroot beer. Dozens of brands of sarsaparilla are made by microbreweries, mainly in the United States.[14]
Sarsaparilla is not readily available in most countries; however, manybars and most major supermarket chains in the Philippines, Taiwan, Singapore and Australia stock sarsaparilla-flavored soft drinks, and sarsaparilla remains available in the United Kingdom as a legacy of thetemperance movement.[15]

The classic sarsaparilla was not made from the extract of the sarsaparilla plant, a tropical vine distantly related to the lily. It was originally made from a blend of birch oil andsassafras, the dried root bark of the sassafras tree. In this context, sassafras should not be confused with common sassafras seasoning,filé, used inCajun cooking and made from dried and ground sassafras leaves. Sassafras was widely used as a home remedy in the 19th century; taken in sufficient doses it induces sweating, which some people thought had health benefits. Sarsaparilla made its debut as a patent medicine, an easy-to-take form of sassafras, much asCoca-Cola was first marketed in 1885 as a remedy for hangovers, headaches and morphine addiction.[16] Besides the effects of the ingredients, sodas were popular in the United States at the time, due to the belief thatcarbonated water had health benefits.[17] In 1960 the FDA banned the use of sassafras oil in foodstuffs after evidence accumulated showing that the main constituent,safrole, was carcinogenic.[18] Safrole is also found in filé, nutmeg, mace, cinnamon, anise, black pepper and sweet basil, but in low enough concentration to be deemed safe.[19][20]

In the Philippines, Sarsi is a brand name for a sarsaparilla drink originally manufactured by Cosmos Bottling Corporation, a local company that is now a subsidiary ofCoca-Cola Beverages Philippines, Inc.[25] Cosmos Bottling Corporation was established in 1918 as Manila Aerated Water Company.[26] Sarsi was originally branded as Cosmos Sarsaparilla until the 1970s. The unique taste that distinguishes the current version of Sarsi from other sarsaparilla-based soft drinks is attributed to the sugar substitutesaccharin, although its "regular" formula containshigh-fructose corn syrup or cane sugar.
In Singapore, F&N Sarsi (originally branded as Sarsi) is a brand name for a sarsaparilla drink manufactured by the Singaporean companyF&N Group (Fraser and Neave). It is unrelated to the brand established in the Philippines.

In mainland China, the drink's introduction can be traced back to the 1920s, whenAS Watson began producing its sarsaparilla drink in Shanghai and other Chinese cities. In the 1940s, Li Zhiyang (李智扬), Li Guanling (李冠玲), Huang Youtong (黄油桶), Liang Hanqi (梁汉奇) and Wang Zhensan (王震山) were among eleven people who had worked in Watson's Canton and founded Asian Waters in Guangzhou to continue producing Sarsae there and in other mainland Chinese locations.[27]
