Meridian essence: modern thought.

Abstract

Meridian essence has been investigated through anatomy, electrophysiology, biophysics, and biochemistry. Various hypotheses of meridian essence exist, but no hypothesis can truly reflect the internal character of Chinese medicine (CM). The research of meridian essence requires a holistic viewpoint and innovative awareness. Initially, any hypothesis regarding meridian essence should begin with observation of the human body. Secondly, the research should arise from the meridians' physical functions and pathological changes, so as to maintain the fundamental nature of the meridians themselves. Thirdly, the research should be based upon the theory of CM, yet coupled with the integration of modern techniques to deepen our understanding of the scientific contents of meridians. Fourthly, theoretical research should be combined closely with clinical practice, in order to test the achievements in actual conditions. Lastly, more attention should be given to negative results in studies to more accurately discover the real essence of meridians.
