The name “ashwagandha” is derived from the Sanskrit word ashwa (“horse”), which refers to the pungent odor of the root. (Others believe that the name refers to the herb’s ability to give users “horse-like” stamina and strength.) In the ancient Indian medical system of Ayurveda, ashwagandha is classified as a rasayana, or “life extender.” Ashwagandha root preparations traditionally have been used to promote sleep, enhance mental function, and increase stamina and endurance, among other functions.

“Of all the medicinal plants used in India’s several millennia old tradition of Ayurveda, Ashwagandha, Withania somnifera, is the most highly prized. Ashwagandha is used in many cases, for virtually every condition.” - Chris Kilham
