About Ashwagandha

Ashwagandha means "smell of a horse" — a reference both to the odour of its fresh root and to the strength it is said to give. It is the best-known Ayurvedic rasayana (rejuvenative) worldwide. Several randomised trials have found that root extracts reduce perceived stress and cortisol. In India it is grown commercially in the dry Neemuch–Mandsaur belt of Madhya Pradesh and in Rajasthan. The root is the part used; leaves are not recommended for internal use.

Botanically known as Withania somnifera, it belongs to the Solanaceae family. It is native to India, Africa and grows best in a arid/semi-arid climate. The parts most often used are the root, leaves and berries.
