Tissue stability and immune function is very important, the body’s immune function is normal or not, and the function of the internal organs, that is, the liver is the main function of excretion has a very important correlation. From the content of the liver’s main excretion, the elevation function of the spleen and stomach, the lungs and heart of the function of the upper focal point, and the lower focal point of the liver and kidneys, normal or not, is closely linked, so to maintain the stability of the body’s tissues, first of all, must be adjusted to the liver’s physiological position of the excretory. The physiological position of the liver must be neither suppressed nor over-excited, which is the significance of the so-called Liver Master of Balance. In terms of the position of the spleen and stomach in the middle jiao, the spleen rises and the stomach descends, and the scheduling of the center is the source of the essence of the latter day, while the heart and lungs in the upper jiao of the main qi, blood function, as well as the liver and kidneys in the lower jiao of the main bone, the main tendon and liver function is also very important. And Dongguan on the spleen and stomach, Danxi on the liver and kidney, by the liver main drainage in the center of the mediation, the two big ideas to the flow of the same source, more realistic and profound significance.
