Stevia refers to a fairly large group of plants and shrubs native to the warmer parts of the Americas. Its leaves have long been used by indigenous tribes as a sweetener and in herbal medicine. In the west stevia has become popular recently as sugar alternative. One of its extracts has been shown to be as much as 300 times sweeter than regular table sugar, without affecting blood sugar levels. This is useful for diabetics, and really for anyone who's watching carbs or calories.
But it gets sweeter (sorry, couldn't resist): Stevia also tones and tightens skin, and reduces the appearance of fine lines and wrinkles. It's also anti-bacterial.
