Often used for its enjoyable flavor in herbal formulations, stevia leaf powder can also be added to smoothies, baked goods, and tea infusions. Stevia leaf powder is ground from the leaves of Stevia rebaudiana, a plant native to Brazil and Paraguay. Stevia leaf has been used for millennia by the Guarani tribe who employ the herb for its healthful benefits and to cut the bitterness of local teas.

Stevia comes from a group of plants that are native to South America. In tropical regions it grows as an evergreen shrub. However, in temperate regions it can be grown as an annual or herbaceous perennial. Stevia leaf also goes by the common names of candyleaf, Paraguayan sweet herb, and sweetleaf. It is a member of the Asteraceae plant family.
