Naturopathy, or naturopathic medicine, is a system of medicine based on the healing power of nature. Naturopathy is a holistic system, meaning that naturopathic doctors (N.D.s) strive to find the cause of disease by understanding the patient as a totality of body, mind, and spirit. Most N.D.s use a wide variety of therapies and techniques (such as nutrition, herbal medicine, homeopathy, and acupuncture).
