Stevia sp


Stevia is a genus of about 150 species of herbs and shrubs in the sunflower family (Asteraceae), native to subtropical and tropical South America and Central America. The species Stevia rebaudiana Bertoni, commonly known as sweetleaf, sweet leaf, sugarleaf, or simply stevia, is widely grown for its sweet leaves. As a 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 up to 300 times the sweetness of sugar, stevia has garnered attention with the rise in demand for low-carbohydrate, low-sugar food alternatives.

Stevia also has shown promise in medical research for treating such conditions as obesity and high blood pressure. 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.

History and use
For centuries, the Guaraní tribes of Paraguay and Brazil used Stevia species, primarily S. rebaudiana which they called ka'a he'ê ("sweet herb"), as a sweetener in yerba mate and medicinal teas for treating heartburn and other ailments. The leaves of the stevia plant have 30–45 times the sweetness of sucrose (ordinary table sugar).

Other studies have shown stevia improves insulin sensitivity in rats and may even promote additional insulin production, helping to reverse diabetes and metabolic syndrome.Preliminary human studies show stevia can help reduce hypertension.



Indeed, millions of Japanese have been using stevia for over thirty years with no reported or known harmful effects. Similarly, stevia leaves have been used for centuries in South America spanning multiple generations in ethnomedical tradition as a treatment of type II diabetes.
