(a) Chinese medicine believes that cupping has the following effects: 1, balance yin and yang Chinese medicine believes that “yin and yang secret, the spirit is the cure.” Maintaining and stabilizing the dynamic balance of yin and yang is an inherent function of the normal body itself. Once this self-stabilizing function is lost, there will be a pathological phenomenon of yin and yang bias. The imbalance of yin and yang in the body is the root cause of disease. Cupping therapy can improve and adjust the physiological functions of the internal organs by sucking a specific part of the body or acupuncture point, so that the body reaches a state of balance between yin and yang. 2, support the righteousness to dispel the evil Chinese medicine believes that “the righteousness exists within, the evil cannot dry.” The process of disease occurrence and development is the process of the body’s positive energy and external evil. In this process, if the righteousness is strong, the evil shall not invade, the disease retreats; if the evil is strong, the righteousness does not overcome the evil, the disease advances. Cupping therapy can stimulate the qi of the meridians, invigorate the weakened internal organs and improve the collective ability to resist disease, while at the same time, through the suction and cupping effect, it can drain out the wind, cold, dampness and blood stasis, and play a role in supporting the positive and dispelling evil. 3, dredge the meridians and channels Chinese medicine believes that “the meridians so determine the death of life, dealing with a hundred diseases, adjusting the virtual reality, can not be inaccessible.” The meridians are the pathways of the body’s blood flow. It spreads throughout the body, internal organs, external limbs and joints, communicate with internal and external, through the upper and lower, the internal organs and external tissues and organs of the human body into an organic whole, so that the function of all parts of the body to maintain a relative balance and coordination. When diseases occur in the body, the function of meridians and blood is dysfunctional, resulting in pathological changes such as qi stagnation and blood stasis, meridian blockage, and pain if not open. Cupping can stimulate and adjust the meridian qi, unblock the meridians, and affect the function of the organs and tissues they are connected to through the meridian system, so that all the veins are unblocked and the organs are at peace, achieving the therapeutic effect of “no pain if they are unblocked”. 4, reconciliation of qi and blood Chinese medicine believes that qi and blood is the basic material of the human body, “internal irrigate the internal organs, external moisten the coup”, is the basis for the physiological activities of the internal organs, meridians, tissues and organs, all tissues of the human body need the supply and regulation of qi and blood to function. If qi and blood are not in harmony, the organs, flesh, tendons and bones will lose moistening, resulting in abnormal functional activities of the organs and tissues, and a series of pathological changes. Cupping therapy has the function of harmonizing qi and blood and promoting the operation of qi and blood. The cupping therapy can activate the blood to remove blood stasis and relieve pain. (B) modern medicine that cupping therapy has the following effects: 1, the role of cupping therapy on the nervous system modern medical research that: cupping therapy is a negative pressure mechanical stimulation, this stimulation can be through the skin and capillary receptors, through the afferent nerve fibers to the cerebral cortex, reflexively regulate the excitation and inhibition process, so that the entire nervous system tends to balance. Cupping therapy has a two-way regulation function, for the human body pathological characteristics to carry out benign regulation. When the body is in a state of excitement, cupping can make it turn into inhibition; when the body is in a state of inhibition, cupping can make it turn into excitement. 2, cupping therapy on the role of the circulatory system in the application of cupping therapy, the local skin has a warm stimulation, can make the local superficial tissue passive congestion, local vasodilation, promote local blood circulation, accelerate metabolism. The improvement of local blood circulation can quickly take away the local accumulation of inflammatory exudates and pain-causing substances, thus eliminating swelling and pain. 3, the role of cupping therapy on the respiratory system Cupping therapy can promote blood circulation in the lungs, improve bronchial secretion and cilia movement, thereby accelerating the elimination of respiratory tract inflammation. Cupping at Lung Yu and Fengmen points can improve the ventilation function and air exchange function of the respiratory tract, and is often used to prevent and treat wind-cold cough, chronic bronchitis, asthma and other diseases. 4, the role of cupping therapy on the digestive system The role of cupping therapy on the digestive system is mainly produced by regulating the movement of organs and affecting the digestive enzymes and other pathways. When the gastrointestinal motility is hyperactive, suction and cupping of the abdomen and back points of the spleen and stomach can appear to inhibit gastrointestinal motility; suction and cupping of abdominal points can strengthen and adjust the function of gastric juice secretion and promote abdominal blood circulation, thus enhancing digestion and absorption. It can treat both constipation and diarrhea. 5, the role of cupping therapy on the immune system Cupping therapy can enhance the phagocytosis of leukocytes and reticuloendothelial system, enhancing the body’s ability to resist disease. Powerful cupping on both sides of the back, before and after cupping, comparing the phagocytic index of leukocytes and serum complement potency, are significantly increased. Cupping of the bladder meridian on the back can significantly improve the immune function of normal human red blood cells. In addition, cupping therapy causes local capillary rupture and local stasis of blood due to strong negative pressure sucking force, which causes autohemolysis phenomenon. Release of histamine, 5-hydroxytryptamine and other neuromediators, through the neurohumoral mechanism, stimulate the function of the whole body, can effectively mobilize the immune system, the treatment of allergic diseases, hypothermia caused by low immune function, etc., have a better effect. 6, the role of cupping therapy on the motor system (1) release muscle spasm cupping therapy can directly inhibit muscle spasm through muscle tension reflex, and indirectly release muscle spasm by eliminating painful lesions. Cupping can stimulate the nerves in a certain area, regulate the functional activity of the blood vessels and muscles in the corresponding area, reflexively release the spasm of vascular smooth muscle, and obtain a relatively obvious pain relief effect. (2) Promote the absorption of edema and hematoma Cupping therapy has a good effect of activating blood circulation and resolving blood stasis, which can accelerate venous reflux and facilitate the absorption of edema and hematoma. (3) Anti-inflammatory and analgesic effect Cupping therapy has obvious pain relief, can promote the decomposition of inflammatory mediators, excretion, elimination of sterile inflammation, to achieve analgesic effect, especially the pain relief effect of the piercing cupping method is particularly prominent. Stabbing cupping method can suck out the local blood stasis, so that the local qi and blood flow smoothly, the pain is naturally relieved. In short, the mechanism of cupping therapy is no more than two aspects, namely, the overall effect and the local effect, through the warm mechanical negative pressure stimulation, causing local and systemic reactions, so as to adjust the overall function of the body, eliminate pathological factors, to achieve the purpose of treatment.
