Naturopathic and allopathic (conventional) physicians are required to study the biomedical sciences at a four-year accredited graduate medical school. Included in this rigorous curriculum are biomedical sciences such as anatomy, physiology, neurology, biochemistry, microbiology, pharmacology, cardiology, minor surgery, and others. Both are required to complete a University undergraduate degree before completing further training at either a naturopathic college or medical school. Both kinds of physicians can diagnose a disease, predict its course, and prescribe treatment. The difference is in the methods of treatment prescribed. Naturopathic and conventional medicines are complementary and can co-exist.
