If you want to know about Osteopathic Medicine from the very beginning and how it has proven itself since then; read "The DOs: Osteopathic Medicine in America."
This is a little off topic, but in relation to this book I wanted to point out some of the irony within the conversation of "D.O. vs M.D."
Almost everyone in the medical community can agree that D.O. and M.D. schools offer the same curriculum. In some cases, Osteopathic schools offer even more science based labs and classes and yes, Osteopathic medical schools also have the coveted OMM lab in addition to all of the other courses involved. What was eye opening to me, though, was the fact that D.O. schools and M.D. schools have been practicing the same classroom techniques since the beginning of the first "official" school of Osteopathic medicine in Kirksville.
An excerpt from the book..
"Stone's veto (of Still's first school proposal) and the urgings of Smith and others who had argues that the DOs training was incomplete finally convinced Still that he had to make changes. By the end of 1896 he had formally lengthened the course of study to four terms of five months each, and at dedication ceremonies of a new college building he announced, "I am now prepared to teach anatomy, physiology, surgery, theory and practice, also midwifery in that form that has proven itself to be an honor to the profession."(28) Several months later the school published a more detailed course outline that also included histology, chemistry, urinalysis, toxicology, pathology, and symptomatology.(29) Thereafter Still's supporters maintained that every subject covered in a standard medical college, with the exception of materia medica, was taught at the American School of Osteopathy." (The DOs: Osteopathic Medicine in America, p. 31)
P.S. "Materia medica" is just another way of saying medicine in Latin language.
