Osteopathic medicine is a branch of the medical profession in the United States that promotes the practice of science-based medicine, often referred to in this context as allopathic medicine, with a set of philosophy and principles set by its earlier form, osteopathy.Osteopathic physicians (DOs) are graduates of American osteopathic medical colleges and are licensed to practice the full scope of medicine and surgery in all 50 U.S. states. The field is distinct from osteopathic practices offered in nations outside of the U.S.—in which practitioners are generally considered neither parts of core medical staff nor of medicine itself; rather, they are considered alternative medicine practitioners. The other major branch of medicine in the United States is referred to by practitioners of osteopathic medicine as allopathic medicine.
By the middle of the 20th century, the profession had moved closer to mainstream medicine. American "osteopaths" became "osteopathic medical doctors", ultimately achieving full practice rights as medical doctors in all 50 states.
