Known as Indian Ginseng, Ashwagandha (Withania somnifera) has been used in Ayurveda for thousands of years as a rasayana (rejuvenative). It is a renowned adaptogenic herb, which means it is used to help the body resist physiological and psychological stress by adapting to the needs of the body. Deeply supportive of many tissues and body systems, including the immune system, the reproductive system, a healthy thyroid, and much more, ashwagandha is a wonderful herb to help nourish overall health and well-being.
