Ashwagandha (Withania somnifera) is an adaptogenic herb traditionally used in Ayurvedic medicine—a traditional Indian medical system dating more than 3,000 years that emphasizes use of herbs, special diets and other unique health practices. Living up to its reputation as an adaptogen, this herb has shown positive outcomes across a wide range of health applications, including positive effects on sexual health, stress, inflammation and rejuvenation, as well as a positive influence on the endocrine, cardiopulmonary and central nervous systems (Altern Med Rev. 2000;5(4):334-46).
