Naturopathic medicine is a distinct system of primary healthcare that addresses the root causes of illness using natural therapies. Naturopathic doctors undergo 4 years of training at an accredited naturopathic medical school and must pass board exams to become licensed. They take a comprehensive, integrative approach, addressing the mind, body and spirit of each patient. Care plans may incorporate clinical nutrition, botanical medicine, homeopathy, physical therapies, acupuncture, and lifestyle counseling to stimulate the body's inherent healing abilities.
