A genus of plants grown for their sweet leaves. The extracted sweeteners of some stevia species are commonly used as sugar substitutes.

Stevia is a low-calorie food as compared to sugar, and its sweet compounds do not feed the fungus that causes yeast infections (candida albicans). For this reason, it is often used as a sweetener in flavored lubricants.

While stevia is generally safe, it can aggravate ragweed allergies in some instances. Possible side effects include nausea and bloating.
