Plant Parts

This plant, Mitragyna speciosa, is highly valued in traditional medicine for its diverse therapeutic properties derived from various anatomical structures. The most significant components used for medicinal extraction are the leaves, which contain the primary bioactive alkaloids. Often, the dried leaf material is prepared into various forms, such as powders or teas, to facilitate consumption. While specific preparations may focus solely on the foliage, some traditional remedies utilize the whole plant material, including the bark and roots, to achieve a broader range of effects. Additionally, the botanical identification of the species often relies on the presence of distinctive stipules, which are small, appendage-like structures located at the base of the leaf stalks.
