Stevia, or sweet leaf, is an herb known for its sweetness. Stevia is native to South America, but is now grown worldwide. Since pre-Columbian times, it has been used as a food and beverage sweetener. Stevia is useful for those who desire, or need, to minimize their sugar intake. It is as sweet as sucrose, but without the calories. In addition, stevia is different than other alternative low/no calorie sweeteners, such as artificial aspartame and sachharin, because it is natural.
