Medical treatment focuses on the disease or the symptom. Chiropractic focuses on the person with the disease or the symptom. Medical treatment usually involves changing blood chemistry. Chiropractic involves restoring nervous system integrity. Medical doctors prescribe medicine. Chiropractors adjust the spine—a common source of nervous system interference.

As a chiropractor, I see the use of many drugs (legal or illegal) as merely symptom treating. Worse, virtually every drug produces unwanted effects. The effects of chiropractic are largely positive effects.
