Winter diseases are treated in summer, meaning that diseases that are good in winter are chosen to be treated in summer. Winter diseases are those diseases that tend to attack or worsen in winter, and the root cause of these diseases is the strong cold and damaged yang. Summer treatment refers to the traditional Chinese medicine method of generating yang energy during the three volt days after the summer solstice, cultivating the capital and strengthening the yuan, in order to dispel the cold evil that has not receded until summer, restore the balance of yin and yang, and achieve a state of yin and yang secrecy, so as to reduce the number of attacks or reduce the degree of attacks in autumn and winter, and even no longer develop, which is the winter disease summer treatment. This is based on the theories of Chinese medicine, such as “nourishing the yang in spring and summer”, “the unity of heaven and man”, “choosing the right time to cure the disease” and “not treating the disease before it happens”. The theory is to take advantage of the most vigorous Yang energy and the fullness of the body’s meridians and blood to regulate the functions of the body’s internal organs and meridians and blood through diet, Chinese medicine, acupuncture, medication and other Chinese medical treatments to enhance the ability to prevent and treat diseases. One of the most recurring diseases in winter is lung disease, such as chronic bronchitis, bronchial asthma, chronic pulmonary heart disease and other diseases. Winter diseases are usually treated externally with acupuncture point compresses, acupuncture point injections, hot compresses, fumigation and other methods. In the summer, the body’s yang energy rises and floats outside, the coup d’état is open, so the qi and blood should be all over the body surface. The Yang deficiency or Yin cold internal condensation of Yang Qi can not be lifted, Qi Qi closed, so it is not conducive to dispel evil. The external treatment method can lead the qi and blood to reach the surface of the body, to promote the evil Qi from the body surface and disperse. In addition, skin administration can also avoid the influence of factors such as gastrointestinal digestive juices and liver first pass effect. The soup is taken internally to treat chronic bronchitis and other diseases in the elderly with satisfactory results. Winter diseases are mainly due to Yang deficiency or coldness, so the most used medicines are pungent and warm products, among which warming Yang is the main one, accompanied by products to dissolve phlegm, pass the ligaments, promote water circulation and move Qi. For example, the treatment of pulmonary diseases with the external application of the medicine of White Mustard Seed, Gan Sui, Yan Hu Suo, Hsiang Xin, Han Xia, Ephedra, Musk, Bambusa, Ice Pills and Angelica dahurica has achieved very good results.
