Stevia Leaf
As a sweetener and sugar substitute, stevia's taste has a slower onset and longer duration than that of sugar, although some of its extracts may have a bitter or licorice-like aftertaste at high concentrations.
With its extracts having over 30 times the sweetness of sugar, stevia has garnered attention with the rise in demand for low-carbohydrate, low-sugar food alternatives. Medical research has also shown possible benefits of stevia in treating obesity and high blood pressure. Because stevia has a negligible effect on blood glucose, it is attractive as a natural sweetener to people on carbohydrate-controlled diets.
For centuries, the Guaraní tribes of Paraguay and Brazil used stevia, which they called ka'a he'ê ("sweet herb"), as a sweetener in Yerba Mate and medicinal teas for treating heartburn and other ailments. More recent medical research has shown promise in treating obesity, high blood pressure, and hypertension. Stevia has a negligible effect on blood glucose, even enhancing glucose tolerance; therefore, it is attractive as a natural sweetener to diabetics and others on carbohydrate-controlled diets.
