What is Stevia?
Stevia is a small shrub like perennial plant which belongs to the sunflower (Asteraceae) family. It is also known as Eupatorium rebaudianum, sweetleaf, honeyleaf and sugarleaf, and sweet herb of Paraguay. The leaves of Stevia are a source of natural zero-calorie sweetener which is considered sweeter than sugar (sucrose). It has been used in South and Central America , Japan and many other parts of the world as a sugar substitute and in the treatment of a number of health conditions for centuries. Initially the leaves of Stevia were consumed fresh or dried but eventually chemists isolated the glycosides called stevioside and rebaudioside from its leaves that give stevia its sweet taste. Stevia also contains phytonutrients, trace elements, minerals, vitamins and volatile oils which give Stevia its nutritional and medicinal properties. In 2008, FDA (The Food and Drug Administration) approved sweetener derived from the herb stevia as safe for use in foods and beverages. The steviols glycosides are now used in herbal supplements, foods and beverages, and as sweetening powders and syrups. Unlike other sweeteners, Stevia can be used in baking and cooking and its lesser amount is ample.
