A sweet discovery
The term stevia has come to be used as a general term for sweetening agents derived from a South American plant called ka'a he' (sweet herb). Used for centuries to sweeten yerba-mate teas and medicinal beverages, and chewed for a sweet treat, it was not until the 1900s that the plant was scientifically classified as Stevia rebaudiana Bertoni, after the Swiss scientist who discovered it, Moises Santiago Bertoni.
