Herbal products continue to be popular among the American public for the treatment or prevention of a number of ailments. The medicinal use of herbs is deeply rooted in human history and folklore, and has been incorporated into the traditional medicine of virtually all human cultures. Strong religious and mystical beliefs have been associated with the healing properties of many herbs. These beliefs, together with the definite physiological and pharmacological effects of various herbs, as well as their economic potential, have been instrumental in the development of human medicine.
