Stevia is a sweetener made from a plant either as an extract (called stevioside) or as a herb.
In the EU Stevia was not permitted for food consumption for a long time. Recently, limited approval was granted. Stevia is very similar to artificial sweeteners in taste and effect. It has a strong bitter aftertaste which is usually covered by the addition of other sweeteners, usually erythritol, sugar alcohols such as maltitol or sorbitol, or artificial sweeteners. People with fructose intolerance in particular should be cautious when sugar alcohols such as sorbitol are added.
