Let's watch "Life and Death Field" first. In other words, whether the meridian function is normal or not determines a person's life and death. "On Ling Shu Hai" said: "Those who marry the twelve meridians belong to the internal organs and the external limbs." "Lingshu Ben Zang" said: "People are meridians, so those who are active in qi and blood must nourish yin and yang, bones and muscles and benefit joints." These original texts clearly illustrate the important role of meridians in human life activities. The reason why people become an organic whole is that the meridians crisscross, entering and leaving the exterior, running through the upper and lower parts, connecting the five internal organs and reaching the skin and muscles. If there is no such communication and connection between meridians, what can human tissues and organs rely on? Qi and blood in human body are more important than circulation, so that zang-fu organs are connected, yin and yang are connected with Yang Can, and the inside and outside are connected. When qi and blood are not circulating, all kinds of connections between zang-fu organs will be blocked, and diseases will occur, which will lead to death in severe cases.
Look at "All Diseases" again. What is said here is that the normal operation of qi in meridians plays an important role in the treatment and rehabilitation of diseases. The great medical scientist Yu said: "If you don't know the zang-fu organs and meridians, it's wrong to speak"; "Lingshu nine needles and twelve elements" says: "dredge its meridians and regulate its blood gas." All the above texts highly summarize that the treatment of diseases and the rehabilitation of diseased bodies must start from the meridians. As we all know, pain is one of the most common symptoms after people get sick. Chinese medicine believes that "pain will not work, and failure will hurt." When the meridians are unblocked, qi and blood can run; Only when qi and blood flow can patients get treatment and rehabilitation.
Talk about "adjusting reality" again. Tone is adjustment, excess and deficiency are indications, not deficiency syndrome, but demonstration. People often use deficiency and deficiency to summarize the nature of syndromes after illness. Traditional Chinese medicine believes that "pathogenic factors are abundant and essence is insufficient". Empirical evidence refers to the syndrome that evil spirits are strong but healthy qi is not deficient, and the struggle between good and evil is fierce; Deficiency syndrome is the syndrome of qi deficiency, hypofunction and low resistance. In the book "Ling Shu Jie Spasm", it is said that "purging in fact can replenish its deficiency", which actually refers to excess syndrome and deficiency refers to deficiency syndrome. For the empirical evidence, diarrhea and stomach spasm should be used, and acupuncture at Zusanli point can slow the stomach; For deficiency syndrome, tonic methods should be adopted, such as acupuncture at Zusanli point, which can strengthen its contractility. Of course, due to the difference between reality and excess, although they all acupuncture Zusanli point, the methods used are different. One uses purgative method and the other uses tonic method. This example shows that meridians have the function of regulating excess and deficiency.
