Ashwagandha (Withania somnifera (WS)) is a small shrub with yellow flowers that is native to India and North Africa. The extract or powder from the plant's roots or leaves are a popular Ayurvedic herb, used for over 3,000 years to aid in relieving stress, increasing energy levels, and improving concentration in humans. Ashwagandha has been shown to reduce stress and anxiety in both animal and human studies.

More than 40 withanolides, approximately 12 alkaloids, and several sitoindosides have been isolated and identified. The plant is also reported to contain high amounts of iron.
