Flower

Withania somnifera, known commonly as ashwagandha[2][3][4] is an evergreen shrub in the Solanaceae or nightshade family that grows in India, the Middle East, and parts of Africa. Several other species in the genus Withania are morphologically similar.[3]

The plant, particularly its root powder, has been used for centuries in traditional Indian medicine.[5] Ashwagandha supplements, typically containing root or leaf powder or extracts, are commonly sold.[4] Its use in herbal medicine and dietary supplements notwithstanding, there is insufficient scientific evidence that W. somnifera is safe or effective for treating any health condition or disease.[3][4]
