The source of the delicious flavor in this drink is a perennial vine, and the flavor is in the roots.
The botanical name for the plant is Smilax ornata.
S. ornata vines have long prickly stems and shiny leaves, and numerous reddish-brown roots. It is the deep roots of this plant that are harvested and prepared for brewing this delicious drink, or tonic, with the flavor similar to root beer, but with the distinctive flavor of anise. People enjoyed this beverage before another popular root-based drink was developed, Root Beer, which used to be made from Sassafras and Sarsaparilla root until a chemical in Sassafras was found to be poisonous.
The vine grows in tropical areas, temperate zones, places like Mexico, the Caribbean, and South America or Central America. It is native to Mexico and Central America.
Sarsaparilla has been used historically, and by some currently, to support the circulatory system and the liver with claims to it's ability to purify the blood. It is called a "Spring tonic" by some because of it's cleansing properties, and Spring is a popular time for health enthusiasts to do internal cleansing and detoxification of the body. It also has tonic properties and has been used traditionally for skin support. It may also promote normal digestion and appetite. One popular site that offers Sarsaparilla encapsulated (affiliate link - use search feature) offers it as Glandular System support.
