Stevia is a naturally sweet and calorie-free leafy green herb that is many times sweeter than sugar.
Stevia is related to lettuce, marigold and chicory.
It has been used safely for hundreds of years to sweeten foods, and today it is grown and used in China, Germany, Japan, South America, Malaysia, South Korea, and Israel. It lasts a long time. Baked products made with Stevia won't brown, but you can still use the sweetener in baking. Just check your baking occasionally by sticking a toothpick in the center to see if it's done. Also, it does not perform like sugar, and you'll need to experiment with the measurements.
