There is a long history of treating cough and asthma with the external application of Chinese herbal medicine to acupuncture points, such as Su Wen? Cough Theory, “He who treats the organs, treats their yu.” Qing? Zhang Lu’s “Zhang’s Medical General? Asthma Gate” records: “Cold croup …… is often effective when applied with white mustard seeds in the three volts of summer. The recipe uses white mustard seed net end one or two, Yanhuo one or two, Gansui and Hessian each half a tael, research fine powder, into the musk half a penny, pestle and pestle, ginger juice mix to apply lung Yu, the plaster, Bai Lao and other points.” This method has been explored in recent times for the prevention and treatment of chronic bronchitis and bronchial asthma, which are prone to attack in winter, and the drugs used are mostly derived from the “Cold Roaring Formula”, which can reduce the frequency of acute attacks of cough and asthma and improve the quality of life of the patients by cultivating Yang and tonifying the lungs and relieving cough and asthma. Because of its remarkable effect, easy operation and safe non-toxic side effects, the application of acupressure is becoming more and more widespread. The “summer treatment for winter diseases” is based on the theory of “nourishing yang in spring and summer, nourishing yin in autumn and winter”, and “the heaven and man correspond to each other”. Taking advantage of the hot climate in the volcano days, the blood and qi flow smoothly, the drug can be better penetrated and absorbed in specific points of the human body, and the application of pungent, warm and phlegm-removing drugs is an external treatment method. The paste time is generally 0.5 ~ 5 hours, if there is no discomfort after the paste, the paste time can be extended appropriately; such as paste after the local itching, tingling, or diabetic patients, the skin is tender and thin patients can be appropriately shortened paste time. During the patching period, avoid blowing the fan directly or being in too cold air conditioning environment to avoid affecting the efficacy of the treatment. Do not take a bath within 5 hours of removing the patch, and do not scrub hard locally. The appearance of redness, light brown pigmentation and small blisters on the skin after the patch is a normal phenomenon; if the blisters are large, the wound should be protected to avoid scratching and prevent infection. During the treatment period, the diet should be light, avoid eating cold, fatty, shrimp, seafood and other hairy things. Acupuncture point dressing is time sensitive, with the best effect on the three volt days. Long-term recurrent lung diseases must injure the spleen and kidney yang, and then form the pathological basis of deficiency of lung, spleen and kidney qi and phlegm in the lung. The spleen is the source of phlegm production, the lung is the reservoir of phlegm, and the kidneys are the main organ for receiving qi. The cause of cough and asthma is mainly phlegm, and the patient mostly has persistent phlegm, which mostly attacks in autumn and worsens in winter, but gradually heals as the natural yang energy becomes more abundant in spring and summer, even if there is evidence of phlegm-heat congestion during the attack, essentially speaking, it is still a deficiency of the root and a symptom of reality. Therefore, it is important to treat cough and asthma during the remission period to support the root and warm the cold phlegm. The three volts of the lunar calendar is the hottest and most vigorous time of the year, the body’s yang energy also grows, coupled with the higher temperature, the human coup draining, qi and blood tend to the body surface, the drug is easy to absorb, so the three volts day acupuncture point compress treatment of cough and asthma disease in line with the law of Yin and Yang four times, can achieve better results. Compress therapy often uses the back of the thoracic vertebrae next to the lung Yu, plaster, fixed asthma and other points. The Nei Jing says: “All impotence, wheezing and vomiting belong to the top.” Cough and asthma are in the lungs, but the back of the shoulder is connected to the lungs, so the use of medicine in the acupoints on the back of the shoulder can make the medicine enter the lungs. Modern research has shown that the back, next to the thoracic vertebrae, near the sympathetic nerve is a pathological reflex zone for diseases of the whistling system, and the acupoints distributed in this zone are effective in treating lung diseases. The acupuncture points on both sides of the thoracic segment of the crest are used to stimulate the sympathetic ganglion (paravertebral ganglion) of the body located in the thoracic segment, reduce the tension of the vagus nerve, reduce the inflammatory exudate of the tracheal mucosa, release the spasm of the bronchi, reduce the resistance to whistling, improve the ventilation function, as well as inhibit the release of allergic mediators by mast cells, thus achieving the purpose of stopping coughing and calming asthma. The meridians are the channels through which the body runs qi and blood, communicates with the inside and outside, runs up and down, and contacts the internal organs. Through local stimulation and absorption through the skin, acupuncture point compresses can play its pharmacological role, so that the qi of the meridians can be regulated and the qi and blood can run smoothly, which can coordinate yin and yang and resist disease and evil; it can also make the drugs reach the corresponding internal organs through the meridians, which can play the role of tonic deficiency and dispel evil for the lung, spleen and kidney. Studies have shown that acupressure can enhance the immunity of the body, increase plasma cortisol and enhance the phagocytic ability of white blood cells, thus exerting therapeutic effects. As an ancient Chinese medicine external treatment method, acupoint dressing coincides with modern medicine transdermal drug delivery theory. Not only does it have the advantages of transdermal drug delivery, such as the drug is not destroyed by the digestive system and decomposed by the liver, it can maintain a stable blood concentration, thus making the drug work for a long and stable time. Moreover, because the stimulation of acupuncture points can affect multi-level physiological functions through meridian sensory transmission, they may produce mutual excitation and coordination effects, resulting in physiological amplification effects, making the external treatment effect of drugs better than the internal effect. The acupuncture point compressing therapy with the effect of warming the lung and dispersing cold, dispelling phlegm. It can play the role of supporting the righteousness and dispelling the evil, improving the immunity of the body, thus reducing the number of attacks in winter, alleviating the symptoms of attacks, and achieving the purpose of both primary and secondary treatment, which has good prevention and treatment for chronic bronchitis, bronchial asthma, and recurrent cold and flu. In the future, further application of modern technology and techniques to strengthen the reform and development of dosage forms can open up a broader prospect for clinical practice.
