American Ginzing? contains a blend of well-known tonic herbs used to boost or enhance basic vital energy. American ginseng root was traditionally used by native Americans, including the Crow, Menomonee and Penobscot tribes, as a tonic to strengthen their mental powers. By the 18th century it was being exported to China where it became one of the more important tonic herbs in the Chinese Materia Medica. Referred to as "xi yang shen," American ginseng is often included in Asian tonic formulas that help with stress and fatigue. Traditional Medicinals' formula also includes the warming qualities of ginger and cinnamon with the balancing aspects of licorice. For best effect, it should be enjoyed daily.
