What system of healing did Canadian-born grocer Daniel David Palmer formally introduce in Davenport, Iowa, in September 1895?
A: Chiropractic medicine.
Although new at the time, the principles upon which chiropractic medicine was based can be traced back to the earliest physicians–including Hippocrates (460-370 B.C.). Palmer created the name “chiropractic” by combining the Greek words for hand, cheir, and practical fo(or efficient). praktikos.
