For energy-related predicaments, many people turn to ashwagandha, increasingly known as the "Indian ginseng." Ashwagandha, or "winter cherry," provides energy and a rejuvenating lift while at the same time offering a calming effect. The chemical components in ashwagandha are remarkably similar to those found in ginseng, and yet studies have demonstrated its superiority in stress-relieving abilities when compared to its Chinese cousin. Ayurvedic healers have long prescribed the herb to treat exhaustion caused by both physical and mental strain, and scientific research has recently borne out this practice. A double-blind study found that ashwagandha prevented stress-related ulcers and vitamin C deficiency, and increased energy and endurance when under stress. Theey to ashwagandha's benefit lies in its action as an adaptogen, or substance that helps the body become more flexible and capable of handling change. This applies especially to the muscles. Indeed, the herb's adaptogenic effect has far-reaching implications. Ashwagandha enjoys the reputation in the West as an aphrodisiac, a use supported by a recent study in which more than 70 percent of men reported increased libido and sexual function after taking the herb.
