Accredited naturopathic medical schools are four-year, in-residence, hands-on medical programs consisting of a minimum of 4,100 hours of class and clinical training. Educated in all of the same basic sciences as a medical doctor (MD), a naturopathic doctor uses the Western medical sciences as a foundation for diagnosis and treatment. Also similar to MDs, naturopathic physicians must pass rigorous professional board exams before they can be licensed by a state or jurisdiction. And, for at least the final two years of the medical program, naturopathic medical students intern in clinical settings under the close supervision of licensed professionals.
NDs, however, also study holistic approaches to therapy with a strong emphasis on disease prevention and promoting wellness. In addition to a standard medical curriculum, NDs are trained in clinical nutrition, homeopathic medicine, botanical medicine, psychology, physical medicine and counseling.
Many receive additional training in areas such as midwifery and acupuncture and Oriental medicine. Because NDs view natural medicines as complementary as well as primary, they cooperate with other medical professionals, referring patients to (and receiving patients from) conventional medical doctors, surgeons and other specialists when appropriate.
