Ashwagandha Root Identity & Plant Part
The species behind this ashwagandha extract is Withania somnifera (L.) Dunal, a member of the nightshade family, Solanaceae. The part used is the root. Leaves, berries and stems are not included. The distinction matters because the steroidal lactones of the plant, the withanolides, differ between organs: the leaf is far richer in withaferin A, while the root carries a different profile. Two chemotypes of the species are described, one led by withaferin A and one by withanolide D. Withania coagulans is a related species sold under a similar trade name and is a different plant. The root also holds starch, alkaloids and sugars beside the withanolide family, and the name ashwagandha refers to the strong smell of the fresh root.
