Ashwagandha Leaf Extract is a standardized adaptogenic botanical extract derived from the dried leaves of Withania somnifera (Ashwagandha), a perennial herb in the Solanaceae family, also known as "Indian Ginseng."

The powder is greenish-brown to brown, fine and free-flowing, with a mild earthy herbal odor. Non-GMO, gluten-free, no artificial additives, it is widely used in stress relief, sleep support, immune enhancement, and skincare across global markets.
