Disease is the abnormal performance of certain functions; the abnormal activity has its causes.
Chiropractic embraces the science of life, the knowledge of how organisms act in health and disease, and also the art of adjusting the neuroskeleton.

Do not forget that chiropractors did not treat diseases. They adjust causes, whether acquired, spontaneous, or the result of accident.
