Acupuncture point application therapy is based on the theory of meridians and collaterals in Chinese medicine, in which the drug is finely ground and mixed into a paste with water, vinegar, wine, egg white, honey, vegetable oil, cooling oil, medicinal liquid or even saliva, or made into an ointment, pill or cake with solidified grease (such as Vaseline, etc.), yellow vinegar, rice or date paste, or boiled into a paste from Chinese medicine soup, or scattered on the paste, and then directly applied to the acupuncture point or affected area ( Ah Yes point), a non-invasive and painful acupuncture point therapy used to treat diseases. It is an important component of Chinese medicine treatment, and is a unique and effective treatment method summarized by the working people of China in their long struggle with disease. The mechanism of action of acupressure is complex and not yet fully understood. We believe that its possible mechanism has the following three aspects: first, the stimulating and regulating effect of acupuncture points; second, the medicinal effect of the drug after absorption; third, the comprehensive superposition of the two. 1, the role of acupuncture points meridians “internal organs, external limbs, communicate with the surface, through the upper and lower”, is the body’s circulation of Qi and blood running out of the human channel, and acupuncture points are the intersection of the above substances in the running pathway, is the “lung gas issued” and The acupuncture point is the intersection of the above-mentioned substances in the pathway of operation, and is the place where the “lung qi is issued” and “the divine qi parades out of the person. According to the theory of the internal organs and meridians, acupuncture points are closely related to the internal organs through the meridians, and not only reflect the physiological or pathological functions of the internal organs, but also serve as effective stimulation points for the treatment of diseases of the internal organs. Various disease-causing evil stays in the body, the function of the internal organs is damaged and affected, resulting in astringency of the meridians, depression and inaccessibility, the flow of Qi and blood is not smooth, then a hundred diseases are born. At this time, abnormalities such as numbness, pain, redness, swelling, nodules or specific sensitive areas (bands) may appear in the meridian circulation areas (especially in the acupuncture points to which they belong). The use of acupuncture point application therapy, stimulating and acting on the body surface acupuncture points corresponding to the skin, through the conduction and adjustment of the meridians, to correct the internal organs of the yin and yang of the bias or decline, “to pass the depressed Qi …… to disperse the swelling of stasis”, improve the operation of the meridians qi and blood, on the five organs and six internal organs The main purpose of the treatment is to help the skin to fix the surface, the surface to hold the poison, the meridians to pass through the organs, the points to drive away the evil, and to support the body. 2, the effect of medicine Xu Da Chun once said: “the soup medicine is not enough to exhaust the disease ……… with ointment paste, occlusion of its gas, so that the medicine from the pores and into its couples, through the meridians, or lifting out of the, or attack and dispersion, more powerful than taking medicine”. . The drug is applied directly to the body surface acupuncture points or surface lesions, so that the local blood vessels expand, blood circulation accelerates, to activate blood stasis, remove heat and toxins, reduce swelling and pain, stop bleeding and produce muscle, anti-inflammatory and drain pus, and improve the role of surrounding tissue nutrition. It also allows the drug to penetrate through the skin and hair couples from the surface to the inside, and through the penetration of the meridians, contacting the internal organs and communicating with the surface and the inside, exerting a strong medicinal effect. As stated in “Li Bo Era”, “cut in the skin, penetrate in the flesh, take in and absorb air, and integrate into the ooze”. And with its use of medicine, it can dispel evil, pluck poisonous qi outward, suppress evil qi inward and clear; it can support righteousness, pass through Ying and Wei, regulate elevation, rationalize yin and Yang, and calm the five organs; it can thwart the five depressed qi, and fund the source of chemistry. We know that the factors affecting the transdermal absorption of drugs are closely related to the inherent permeability of the skin, in addition to the physicochemical and pharmacological properties of the drugs. Modern medicine has proven that Chinese medicine can be absorbed through the skin. The main ways of drug absorption through the skin are: one is transdermal absorption, through the arterial channel, the stratum corneum transit (including intracellular diffusion and intercellular diffusion) and deep epidermal transit and be absorbed, the drug can enter the blood circulation through one or more pieces of pathways; second is hydration. The stratum corneum is the main barrier to transdermal absorption, its water content is a function of the relative temperature of the environment, the external application of traditional Chinese medicine, “the form attached to the Li but not away”, “the gas is closed but not leaking”, the local formation of a sweat is difficult to evaporate diffusion of the closed state, so that the water content of the stratum corneum from 5% to The water content of the stratum corneum increases from 5~15% to 50%, and the skin hydrates after the stratum corneum absorbs water, causing the cells of the stratum corneum to expand into a porous state and making its tight structure loose, which makes it easy for the drug to penetrate. Studies have shown that the rate of drug transdermal can therefore increase 4-5 times, but also to increase the skin temperature from 32 ℃ to 37 ℃, accelerating local blood circulation; third is the role of surfactant, the lead soap contained in the patching drug is a surfactant, can promote the absorption of passive diffusion, increasing the epidermal lipid membrane on the drug permeability; fourth is the role of aromatic drug promotion, the patching formula of aromatic drugs, containing more Volatile olefins, aldehydes, ketones, phenols, alcohols, its strong penetration and runaway, can make corticosteroids transdermal ability to improve 8 to 10 times. 3.Comprehensive effect Acupuncture point application therapy is the organic combination of traditional acupuncture therapy and drug therapy, in essence, is a kind of meridians, acupuncture points, drugs as a composite treatment method, rather than just a simple factor in action. We know that in general a drug taken internally can cure a disease, with a drug applied externally can also cure a disease, such as internal use of mannitol can cure constipation, with mannitol compress umbilical can also cure constipation. But sometimes there are exceptions, that is, the external application of a drug compress can cure a disease, but the internal use of a drug can not cure a disease, such as onion white effect umbilical can cure constipation, but onion white internal use can not cure constipation. In addition, there are many cases in which a single drug, such as fried onion, fried salt, garlic, etc., is applied externally to the affected area to treat different types of diseases. We believe that in addition to the effective bioactive substances of Chinese medicine, there is also the external sensitizing and amplifying effect of warming and heat stimulation and the meridian acupuncture points themselves. We have also found that the efficacy of treating the same disease varies with the use of different medicines at the same acupuncture point. For example, for the same asthma treatment, the asthma pill (white mustard seed, Yuanhu, Gansui, Hosanna, clove, cinnamon, and ginger juice) is significantly better than the asthma paste (tiannanxing, white mustard seed, and ginger juice), indicating that medicinal properties also play a role. In some cases, different parts or acupuncture points are chosen according to the disease, which shows the role of acupuncture points and meridians. For example, the cough patch Tiantu. Set asthma, lung Yu has a significant effect, while the patching of it points or non-acupuncture points is not effective; urine loss, dysmenorrhea patching preferred Shen Que point. This shows that the main performance of acupuncture point compresses on the human body is a comprehensive effect, both the stimulation of the drug on the acupuncture point, and the role of the drug itself, and in general is often the overall superimposed therapeutic effect of several therapeutic factors interacting, interacting and complementing each other, the first is the adjustment of the local qi and blood by the warm stimulation of the drug, and the warm stimulation with the external application of the drug is bound to increase the efficacy of the drug. The external application of drugs on acupuncture points stimulates the acupuncture points themselves, stimulates the meridian qi, mobilizes the function of the meridians, and enables them to better play the overall role of moving the qi and blood, and nourishing the yin and yang.
