The puzzle of acupuncture.

Acupuncture is based on the theory of channels, which serve as pathways for energy (Qi). On the course of the channels, acupuncture points are described, and by stimulation of these points, therapeutic effects may be achieved. This system is very complex and both channels and acupuncture points are anatomically invisible. Unlike in Western medicine, scientists fail to trace both the origin and the progress of acupuncture theory. Having developed in its full form not later than the 2nd century BC, it never underwent fundamental change. On the other hand, it has become a part of modern Western medicine as an effective therapy and the existence of acupuncture points, specified thousands of years ago, has been demonstrated by modern science. It is hardly probable that acupuncture theory, although dating back to ancient times, could have originated in primitive civilization. The origin of the energy channel theory does not fit into the traditional developmental scheme. The existence of the theory cannot be explained other than by its being a product of a highly developed civilization.
