Dried Stevia leaves in 40g bag format. Natural stevia is a plant of humble appearance, native to South America, specifically Paraguay. "Stevia" is a genus of 240 species of tropical and subtropical plants, but when we talk about stevia we are referring to Stevia Rebaudiana Bertoni. Stevia has become popular because of the sweetness of its leaves, which are between 15 and 30 times sweeter than sugar, which is why it has been used since ancient times by indigenous peoples who used it to sweeten drinks, such as mate, and chewed its leaves for their sweet taste. Currently, natural stevia is a sweetener of choice when we want to avoid the pro-inflammatory and extreme effects of some other natural sweeteners.
