The three volt days are determined according to the ancient “stem and branch chronology” in China, both of which originated in the Spring and Autumn period, when the theory of Chinese medicine also became more mature. The third G day after the summer solstice (the day with the word “G” in the stem-branch chronology) is the first volt, the fourth G day is the middle volt, and the first G day after autumn is the last volt, which together are called the three volts. It occurs from mid-July to mid-August, and is the hottest time of the year in most parts of China, as the saying goes: “Small summer and big summer are closely connected, and the temperature rises hot. Chinese medicine believes that the human body’s yang energy, which resists external evil, is at its peak at this time. For seasonal health care principles, Chinese medicine advocates “nourishing yang in spring and summer, and nourishing yin in autumn and winter”, in line with the summer heat, to protect the body’s yang energy has an important role in disease prevention. The “volcano” refers to the cold air of autumn hidden in the summer heat, Geng in Chinese medicine theory of the five elements of yin and Yang corresponds to gold, the lungs also belong to gold, so “Geng day” corresponds to the lungs, in this day the lung meridians of qi and blood is most vigorous. Therefore, although the three volts of compresses can treat a variety of diseases, it is most suitable for diseases of the lung system. Chronic bronchitis, emphysema, bronchial asthma, allergic rhinitis, recurrent colds and other diseases belong to the lung system, and most of them are serious in winter and relatively relieved in summer. For these patients, there are varying degrees of Yang deficiency or Wei Yang deficiency, which is dominated by lung qi and has the function of resisting external disease and evil, representing the immunity of the body. In the three volt period, choose Chinese medicine with the effect of “warming the Yang and dispersing the cold, warming the meridians and opening the channels” to apply on the back, the back of the foot sun bladder meridian for the human body “giant Yang” place, “the rational boiling parallel text” said “the skin and hair of the lung also. …… lung system belongs to the back”, lung Yu for the lung Wei Wei meridian qi infusion, with heart Yu, diaphragm Yu, acupuncture point external medicine with the meridian qi into the lung, heart, diaphragm and other parts of the function of invigorating Wei Yang, phlegm and asthma. The treatment of the three volcanoes, when the yang energy of the earth is at its peak and the lung meridian qi and blood are in full bloom, will be twice as effective with half the effort. This is the so-called winter disease and summer treatment, that is, for serious lung diseases in winter, choose to treat them in the summer when the Yang energy is strong. Based on the ancient recipe of the Qing Dynasty, a number of old experts from Guang’anmen Hospital of the Chinese Academy of Traditional Chinese Medicine researched and improved the preparation from the composition of drugs, drug concoction, preparation process, treatment points and treatment time, and gradually formed a fixed formula and operation method. The method comes from the ancient moxibustion therapy, written in the Spring and Autumn and Warring States period of the “52 disease formula” in the mustard seed clay on the hundred points to treat poisonous snake bite records: “W, …… to thistle seal which upside down”. In the Qing Dynasty, the “Zhang’s Medical General? The “white mustard seed method” contained in the “All Qi Gate” of the Qing Dynasty is the originator of our antiasthmatic cream. In the formula of the antiasthmatic cream, white mustard seeds can help dispel phlegm; ginger is pungent and warm, disperses phlegm, dispels phlegm and dampness, disperses wind and cold and stops coughing; ephedra is pungent and warm, calms asthma, relieves congestion of lung gas and disperses yin-cold condensation, which can “open the nine orifices and regulate blood vessels. The whole formula has the effect of warming Yang, dispersing cold, expelling phlegm, clearing the ligaments, and relieving gas and asthma. For more than 50 years, our hospital has treated tens of thousands of patients and has achieved excellent clinical results. Over the years, our experts have conducted many systematic studies on this therapy and found that the overall efficacy of antiasthmatic cream in treating chronic obstructive pulmonary disease and asthma is about 60% to 80%, and it has good efficacy in preventing acute exacerbation of chronic cough and asthma, among which the efficacy is better for chronic obstructive pulmonary disease, and it can significantly reduce the number of cold attacks. In addition, it was found that there was a significant positive correlation between the number of times of patching treatment and the long-term efficacy. The local symptoms of the respiratory system not only improved after the patching, but also the systemic defense function was enhanced. Statistics on the correlation between the types and efficacy show that the efficacy of deficiency cold types such as deficiency of spleen and kidney and deficiency of lung qi is better than that of deficiency of lung and kidney yin. In recent years, the summer treatment of winter diseases has become increasingly popular, and this therapy has the characteristics of “simple, convenient, inexpensive and effective”, but there are certain misunderstandings in its application: first, on the whole, this is an auxiliary therapy, which cannot be relied on to solve all the problems, and patients should not arbitrarily stop using other drugs they are using after the application. Secondly, the method cannot cure all diseases, the most suitable is the above-mentioned pulmonary system diseases. It is the right time to treat winter and summer diseases, and care should be taken when applying it.
