The weather is getting colder day by day, and more people come to see traditional Chinese medicine for cupping treatment. People choose cupping in winter mostly to expel the cold in their body, while cupping can expel moisture in summer. In the classical therapy of traditional Chinese medicine for health preservation, the status of cupping is not general. Can it improve immunity and prevent diseases? What precautions should be taken when applying it? Is the saying that "color corresponds to disease" reasonable? What is the scientific principle of cupping therapy Cupping is a folk term for cupping therapy, also known as "cupping" or "suction tube". Cupping therapy is also called angular therapy in ancient books. The definition of modern cupping therapy is an external treatment method that uses the jar as a tool to cause negative pressure in the jar by means of combustion, suction and steam, so that the jar can be adsorbed on a certain part of acupoints or body surface, and produce benign stimulation, so as to adjust body function and prevent diseases. So, what is the scientific principle of cupping? The therapeutic principle of cupping is well understood, that is, by causing local tissue congestion or subcutaneous mild blood stasis, the body's Qi and blood activity is vigorous and the meridians are unobstructed. Therefore, traditional Chinese medicine says this method has the functions of dredging meridians and activating collaterals, promoting qi and blood circulation, reducing swelling and pain, dispelling wind and dispersing cold, etc. In the theory of traditional Chinese medicine, evil Qi and blood stasis are two common causes of disease. Evil Qi generally refers to all kinds of pathogenic factors, including factors with pathogenic effects produced by the outside world and the human body, such as cold evil easily felt in winter and wet evil easily felt in midsummer; Blood stasis mostly refers to the blockage of Qi and blood and the obstruction of meridians. The function of Zang Fu organs requires the operation of Qi and blood. Regulating qi and regulating blood flow is the performance of human health. If blood stasis occurs in the human body, it will lead to the disorder of Qi and blood operation, the dysfunction of Zang Fu organs and their meridians, and then lead to diseases. Cupping therapy has the dual functions of warming and dredging meridians and removing evil Qi, so as to achieve the purpose of curing diseases. "Meridian theory" is one of the important theoretical bases of traditional Chinese medicine. Its external and internal communication characteristics are the reason why cupping therapy can regulate the yin-yang function of Zang Fu organs. Among them, "Twelve skin Department" is an important part of communication. "Twelve skin parts" refer to the body surface parts of the human body. According to the meridian theory, the twelve meridians and their collaterals of the human body have their corresponding areas on the body surface according to their routes, and are divided into twelve parts accordingly. "Twelve skin" is not only the part directly stimulated by cupping therapy, but also the key to the curative effect of cupping. The stimulation of the skin can affect the viscera through the meridians, so as to dredge the meridians, support the right and dispel the evil, and adjust the Yin and Yang. Modern medicine also believes that cupping has mechanical stimulation, warm stimulation, regulating microcirculation and negative pressure hemolytic effect. Mechanical stimulation and warm stimulation of cupping can accelerate local blood circulation, promote metabolism and improve local microenvironment; Negative pressure adsorption causes local capillaries to rupture, which will cause local microenvironment changes under the stimulation of outflow blood, so as to activate the regulatory function of human nerve humoral immunity and play a role in the treatment of diseases. Who is suitable for cupping As mentioned above, cupping has a wide range of adaptability. It is not only commonly used for wind cold and dampness arthralgia, but also for soft tissue flash contusion, headache, epigastric pain, abdominal pain, cough, asthma, diarrhea and other diseases. Here are some examples of these effects of cupping. For asthma, Feishu, Geshu, Tanzhong, Tiantu and other acupoints can be selected, and the flash pot method and retention pot method can be adopted. 1-2 times a week, 4 weeks as a course of treatment, the symptoms can be significantly improved after a course of treatment, and recurrence is rare. Headache disease, clinical common exogenous headache and blood stasis headache, among which exogenous headache can be selected from Fengchi, Taiyang and other acupoints; For blood stasis headache, Ashi point can be selected, and flash cupping method or blood pricking cupping method can be used. Once a day or once every other day, three times is a course of treatment. After a course of treatment, the pain symptoms can be improved or even disappear. For low back pain, Shenshu, colorectal Shu and Ashi points can be selected for flash cupping method, cupping method and retention cupping method. Those with obvious blood stasis can be pricked and cupping method. Those with severe cold and dampness can increase the operation strength and time of cupping method and retention cupping method. Those with severe cold evil can be added with water cupping method or medicine cupping method. Once every other day, 2 weeks as a course of treatment, can significantly relieve pain. Cupping therapy has no obvious pain and trauma, so it is safe to use. It is also applicable to the elderly and children, but the tank retention time should be shorter than that of other age groups, and the operation strength should be lighter. In general, it is not recommended that pregnant women receive cupping treatment, but for some specific diseases, such as facial paralysis during pregnancy, cupping operation behind the face and ears will be carried out as appropriate, and attention should be paid not to be too heavy. It should be noted that cupping is not suitable for highly allergic skin, infectious skin diseases, skin tumors (lumps) and skin ulcers. Novel coronavirus pneumonia is associated with acute severe diseases such as acute cerebral hemorrhage, gastrointestinal perforation, acute myocardial infarction, pneumothorax, and contagious diseases such as varicella, hand foot mouth disease, syphilis, AIDS, malaria, new crown pneumonia, active pulmonary tuberculosis, heart failure, convulsion, emotional impulse, anxiety and incompatibility, and acute traumatic fractures, moderate and severe edema. Cupping should not be used in affected areas such as purulence and hernia. Is the colder the can print color After cupping, people's skin may have can marks of different colors. The common ones are flake purplish red ecchymosis, blood stasis, or slight heat pain. They are collectively referred to as can spots or can marks. This is a normal reaction after cupping and disappears after a day or two. Many people believe that "what color you pull out corresponds to what disease" or "the more blue and purple the color, the heavier the cold in your body". Is this true? The color of the tank seal is blue and purple, indicating that there is blood stasis block in the body, but it is not necessarily cold, because cold evil, heat evil, wind evil and wet evil invade the reason, which can lead to qi stagnation and blood stasis. It is necessary to further clarify the etiology and can not be confused. In the theory of traditional Chinese medicine, the color of can print is indeed related to disease classification. Generally speaking, the bright red color of can printing is more common in Yang Syndrome, excess syndrome and heat syndrome; The dark red color of the can is Yin Syndrome, blood stasis and cold syndrome. After cupping, the skin of healthy people is only slightly red and will soon return to normal; People with heat, cold and blood stasis in the body may have purple black and cyan skin after cupping; For people with toxin and blood stasis, the can print is dark purple and black, and they feel pain when touching it; People with Yin deficiency and internal heat may have red skin after cupping; For people with heavy moisture, the can print is flushed, and blisters, beads or water vapor may appear on the skin after cupping; Those who feel the wind evil will feel the slight itch of the pot print; For people with weak body or thick fat, the can printing color is light or the skin color may not change. However, the greater the negative pressure of cupping and the longer the time of keeping the tank, the easier it is to deepen the color of the tank print, and it is also easier to pull out blisters and even cause skin infection. Therefore, the retention time of cupping is generally 5-10 minutes, the longest should not exceed 15 minutes, and it also needs to vary from person to person. It is easy to cause excessive damage to capillaries, blisters or serious inflammatory reaction. Is it the doctor's fear of trouble to leave only cans Cupping can be divided into cupping method, water cupping method and air extraction method according to adsorption method. Cupping is the most common way of cupping. The common methods are flash fire method and fire throwing method. Generally, the operation method seen in regular hospitals is mainly flash fire method. Maintaining the hot gas in the tank is the basis for forming negative pressure. With the progress of the times, the use of sustainable burning alcohol ignition rod makes the flash fire method more safe, efficient and standardized. Therefore, the flash fire method gradually replaced the fire throwing method and became the mainstream operation method. The water pot method is to boil the bamboo pot in water or liquid medicine for 2-3 minutes, then clamp the pot upside down with tweezers, quickly cover the mouth of the pot with multi-layer dry towels for a moment, place the pot at the place to be pulled while it is hot, and then gently press the pot for about 30 seconds to make it suck firmly. The advantage of the pot method is that Chinese medicine can be added when boiling water, but because it is not easy to control the heat in operation, people with diabetes, sensitive skin or tender skin should be applied as appropriate. The air extraction method is to fasten the air extraction tank to the part to be pulled out, and use the air extraction device to extract part of the air in the tank to make it suck and pull out on the skin. This method is often used in family daily use, but it should be operated under the guidance of doctors. After introducing the adsorption method, let's talk about the operation method. The operation methods are divided into flash tank method, retention tank method, walking tank method, needle tank method and medicine tank method. There is a saying that cupping does not take the can because doctors are afraid of trouble. The effect of leaving the can without taking the can is not good. In fact, the choice of operation method depends on the patient's specific symptoms and cupping position. The flash cupping method is to suck and lift repeatedly. It is suitable for deficiency syndrome patients with relatively loose muscles, loose suction and pull, or difficulties in retaining the cupping, as well as local skin numbness or hypofunction. A muscular back and waist is not suitable for this method alone. The cupping method is the most common cupping method. It is suitable for most people. It is the most commonly used cupping method in clinic. The can walking method is to push back and forth at the required parts after the can is sucked. It is generally used for parts with large area or rich muscles, such as waist, back, thigh, etc. This method has a strong effect on dredging meridians and Qi and blood, and will have a certain pain. Children with weak constitution or children should use it with caution and pay attention to the operation strength. Needle cupping method: Cupping is performed at the acupuncture site after needle retention or needle exit. It is suitable for various soft tissue injuries, neurodermatitis, acne, skin pruritus, erysipelas, asthma, sciatica and other diseases. This method needs to cooperate with the operation of different needles. Those who are too nervous or sensitive to pain should use it with caution. In addition, attention should be paid to standardized disinfection. The medicine pot method is the medicine cooking pot mentioned above. In addition, there is a medicine storage tank. Medicine pot is mostly used for rheumatic pain; The medicine storage tank is mostly used for rheumatic pain, asthma, cough, cold, chronic gastritis, dyspepsia and psoriasis. This method needs to carry out syndrome differentiation prescription according to the patient's disease and syndrome, and pay attention to observe whether the patient has skin allergic reaction. Those with allergic constitution or skin sensitivity should use it with caution. There are potential safety hazards in cupping at home At present, there is no clear clinical and evidence-based evidence that cupping is suitable for health care of healthy people. According to traditional Chinese medicine, health means that the blood and Qi of the meridians are unobstructed, the functions of the Zang Fu organs are harmonious, and the human body is in dynamic balance. Cupping, as a traditional Chinese medicine therapy, is also a way to interfere with human body balance, so as to turn pathological imbalance into healthy balance. Therefore, regular cupping is not recommended for people without definite diseases. When the body is not in time, you can go to a professional institution for syndrome differentiation and treatment, and cupping treatment under the guidance of traditional Chinese medicine. Before cupping, pay attention not to overwork, wind, hunger or satiety. After cupping, pay attention to avoid wind and cold, drink more water appropriately, promote body fluid circulation and increase metabolism. Although the safety factor of cupping is high, the operation is professional. In news reports, we have seen such cases: a woman spent nearly 10000 yuan on cupping treatment in a health salon, then had a fever and an abscess in the cupping area on her back. Health museum staff called these "detoxification" performance. Subsequently, the woman was sent to the hospital due to coma. She was diagnosed with secondary back scald caused by cupping and needed hospitalization. We believe that cupping without the supervision of doctors has potential risks. We recommend that you do not operate at home or cupping in non-standard health care places. When cupping in an unqualified organization, there is still a problem of tank body elimination
