Sarsaparilla is a term for several tropical plants in the genus Smilax, as well as the aromatic flavouring made from their roots. It has a long history in traditional medicine and was once widely used to flavour soft drinks and root beer. The name is also sometimes applied to unrelated North American plants such as wild sarsaparilla, Aralia nudicaulis.

Definition and naming

Sarsaparilla is a common name for several Smilax species and for products made from their dried roots. The term is also used more loosely for flavourings and beverages derived from those roots.

Plant characteristics

Smilax species associated with sarsaparilla are typically climbing or trailing vines with prickly stems and long roots. They grow in hot, humid environments and are harvested after several years of growth.

Traditional and commercial uses

The roots have been used in herbal medicine and as a flavouring in beverages. Sarsaparilla was historically used in traditional medicine for conditions including skin disease and syphilis. In modern use, it is mainly associated with flavouring, herbal supplements, and root beer-style drinks.

In North America, the name can also refer to wild sarsaparilla, Aralia nudicaulis, which is not a Smilax species. That plant belongs to the ginseng family and has its own separate uses and biology.
