Only refined stevia extract is approved for use as a food additive by the FDA, explains Mayo Clinic. It is commonly used by people who are trying to lose weight.

Stevia was first discovered more than 200 years ago in South America, according to the Global Stevia Institute. It was used by indigenous people to sweeten beverages. In the 1930s, French chemists isolated the sweet components of the plant, and in the 1970s, stevia extracts were used commercially in Japan. Stevia extract was approved by the FDA in 2008, and it has increased in popularity since then. Stevia extracts are now found in sodas, sports drinks and sweetener packets, according to WebMD.
