Meridian Studies in China: A Systematic Review

AbstractMeridian theory is a major part of Chinese medicine and has guided acupuncture and clinical practice for thousands of years. Meridian theory describes many important concepts about the rules of human body function and regulation, but has comparatively huge differences with the basic concepts of modern medicine. These differences have caused deep concern and attracted attention from scholars, both inside and outside of China. The interest in meridian theory lies in determining the structural nature of meridians. Not only is this information still unclear, it is very difficult to achieve clear results in a short period of time. Despite this, the phenomena of meridians can be used as the entry point for meridian studies.After many years of effort, although the physical structure of meridians has not been found, the existence of the meridian phenomena has been fully confirmed. Although there is a lack of morphological evidence for the existence of the meridian, concluding non-existence may be incorrect as morphology techniques develop and structures previously not determined are being found. Since the phenomenon of meridians exists, some biological basis behind its occurrence must be present. This implies that research on meridians needs to continue as research techniques advance and may eventually reveal the biological basis of the meridian phenomenon. In the present review, we analyze the history of meridian studies in China
