ACUPUNCTURE: HISTORY OF CHANNEL THEORY
Acupuncture channel theory was developed on a post hoc basis. Centuries of observation realised the existence of tender areas on the body during times of disease. It was observed that when stimulation was applied to these areas with massage or heat it lead to a gradual recovery of disease. The areas of the body which were sensitive during times of disease evolved to become what we now know are acupuncture points.
