Today we will talk about how acupuncture cures diseases. According to Chinese medicine, the main role of acupuncture is to “harmonize qi and blood, dredge the meridians”. Qi in Chinese medicine, in addition to representing the breathing air, but more importantly on behalf of the body’s various substances, physiological functions and pathological manifestations. For example, the function of the human body to resist diseases is called “positive qi”, and the lack of the function of the human body to resist diseases is called “qi deficiency”. For example, the digestive and absorptive functions of the stomach and intestines are called “gastric qi”, and the lack of digestive and absorptive functions of the stomach and intestines is called “gastric qi deficiency”. Chinese medicine believes that the relationship between qi and blood is interdependent and interdependent, specifically, “blood is the mother of qi”, “qi is the commander of blood”. It means that all tissues of the human body need blood to supply nutrients in order to produce various functions, so it is said that “blood is the mother of qi”. However, blood transportation to the various tissues of the body, but also need cardiovascular power, so that “qi for the blood of the handsome”. Therefore, if a person’s qi and blood functions are harmonized, his body will be healthy; if the qi and blood functions are dysfunctional, diseases will occur. The role of harmonizing qi and blood is known as “adjustment” in modern times. The so-called adjusting effect refers to correcting the body’s function bias or bias decline, so as to keep it in balance and achieve the purpose of curing diseases. A large number of clinical practice and experimental studies have shown that this adjustment effect of acupuncture is different from the general therapeutic effect of drugs. For example, when the brain function is in a highly inhibited – comatose state, acupuncture Renzhong point, can play a role in the excitement, called “wake up and open the mind”. When the brain function is in a state of excitement – patient mania or severe insomnia, acupuncture Renzhong point, can play an inhibitory effect, called “tranquilizing the mind”. The same point has two opposite effects in two different diseases. For example, when the stomach spasms, the tension of the stomach increases, acupuncture foot Sanli can play a role in relieving spasms; on the contrary, when the tension of the stomach decreases, such as gastroptosis, acupuncture foot Sanli, and can make the tension of the stomach increase. There are so many examples of this kind of acupuncture. Therefore, it is believed that the adjusting effect of acupuncture is a “two-way adjustment”.
