Adaptogens

from the back cover of the book Adaptogens by David Winston and Steven Maimes.
"We all deal with stress every day, and every day our bodies strive to adapt and stay balanced and healthy.
...adaptogens, nontoxic herbs such as ginseng, eleuthero, and licorice, that produce a defensive response to stress in our bodies. These rejuvenating herbs and tonics help the body to "adapt" to the many influences it encounters. They increase stamina and counter the normal effects of aging and thus are becoming important tools in sports medicine and in the prevention and treatment of chronic fatigue and other stress related disorders."
