Overview
Ashwagandha Extract is a natural plant extract produced from the dried roots and rhizomes of Withania somnifera (L.) Dunal through extraction, separation, purification, concentration, and drying processes. Ashwagandha is also known as Indian Ginseng, Winter Cherry, or Sleeping Cherry. It is one of the most widely used and important adaptogenic herbs in Ayurvedic medicine. The core active component of Ashwagandha Extract is Withanolides, a class of naturally occurring steroidal lactone compounds with 28 carbon atoms. Over 40 steroidal lactone compounds and more than 12 alkaloids have been isolated from Ashwagandha [8†L5-L7]. Among these, Withaferin A, Withanolide A, and Withanolide D are the most extensively studied key active components. Withanolides help the body adapt to physiological and psychological stress and restore homeostasis by regulating the body's stress response system.
The efficacy of Ashwagandha Extract arises from the synergistic action of multiple active components:
