Indian native plant that is indispensable in Ayurvedic medicine. Widely employed to ward off anxiety and as a sleep aid. The roots are the part that is traditionally used, being available the second year from planting, except in long-season, hot-summer areas, where they may be harvested the first year. The berries look like tiny tomatillos (to which they are indeed related) but are not considered edible, although they have been employed as a rennet substitute in cheese-making. Often referred to as Indian Ginseng because of the many beneficial uses ascribed to it for centuries.
