Study on the relationship between meridians, acupoints and internal organs
According to Yellow Emperor’s Internal Classic records "the twelve meridians belong to the internal organs and the external collaterals are on the limbs", indicating that the function of the meridians is not only to run the vitality and blood to supply the tissues and organs of the whole body, but also to connect the organs to which it belongs and the acupoints on the body surface. How the meridian connects the acupoints and the viscera is still a mystery. In this study, metabolomic analysis were used to examine the heart and stomach tissues in rats and found that 2-Hz electroacupuncture at Neiguan (PC6) and Jianshi (PC5) for 5 consecutive days, 20 minutes a day. The effects on the heart and stomach tissue metabolites are similar. It has been scientifically verified that acupuncture at Neiguan can connect to the heart and affect its function, as well as the connected stomach. In addition, the results are also consistent with the "Heart, Chest and Stomach" recorded in the Shizong Point Song.
