Is an osteopath DO just like a chiropractor DC but just get extra training about wholistic philosophy?

An osteopathic physician (DO) is the clinical and legal equivalent of an allopathic physician (MD). Osteopathic physicians use manipulation, medication, or surgery to prevent or correct alterations in health.

A chiropractor is not a physician and cannot prescribe medications. They perform manipulations of the musculoskeletal system to prevent or correct alterations in health.
