Plant Parts

This plant, Stevia rebaudiana, is a multifaceted medicinal herb where various components offer unique characteristics. The most significant part is the leaves, which contain the natural non-nutritive sweeteners responsible for its fame. From these leaves, concentrated leaf extracts are derived to produce pure steviol glycosides for culinary and therapeutic use. While the plant features a slender, upright stem that supports its growth, the roots can also be utilized in certain traditional practices. Additionally, although the plant produces seeds for reproduction, they are not typically the focus of its commercial or medicinal value.
