Ashwagandha, also called “Indian ginseng,” is an ancient herb used in traditional medicine to combat stress and promote relaxation. As an adaptogen, it helps your body cope with physical and mental stressors by influencing stress hormones like cortisol. Commonly taken as root extract in capsules or powder, it’s widely used to improve sleep, reduce anxiety, boost energy levels, and support exercise recovery.
