Reviewed by Eileen Sibley · M.S. Ayurveda candidate, MIU ·
Often called "Indian Ginseng," Ashwagandha has been a cornerstone of Ayurvedic Rasayana (rejuvenation) therapy for thousands of years. Its name in Sanskrit translates to "smell of the horse" — a nod to its earthy aroma and its traditional reputation for imparting the strength and vitality of a stallion.
