Cough is the most common symptom in respiratory outpatients. While emphasizing the identification of symptoms, TCM treatment should also be based on the theoretical thinking of “Heaven and Man correspond to each other” and the “three factors” principle of season, place and person. In the clinical consultation, according to the seasonal climate, we can grasp the characteristics of the disease to achieve significant results. In the Central Plains region, the four seasons are distinct. In winter, when the climate is cold and dry, coughs are more common due to external wind and cold, and more commonly used formulas include Ma Huang Tang, San Wu San, Er Chen Tang, etc. If there are also heat symptoms, drugs such as Scutellaria baicalensis and Zhe Bei Mu can be added to clear heat and resolve phlegm. Yu Xueqing, Department of Pulmonary Diseases, The First Affiliated Hospital of Henan College of Traditional Chinese Medicine, in spring, there are many winds and sands, and the climate is dry, so the more commonly used formulas are Sang Ju Drink, Sang Apricot Drink, Apricot Su San, and Clear the dryness and save the lung soup, etc.; because the temperature rises quickly and the spring time is short, the drugs are mostly cool and sweet. In summer, when the temperature is higher, more pungent and cooling agents are used, such as Yin Qiao San, Sang Ju Drink and Sang Bai Pi Tang, but the selection should be made according to the concurrent symptoms. In summer, attention should be paid to increasing aromatic and spleen-awakening drugs to strengthen the spleen, resolve dampness and eliminate the generation of phlegm. In the early autumn, warm dryness is the mainstay, and Mulberry-Apricot Drink with the addition of maitake, sage and smallpox powder is mostly used to moisten the lung and nourish the yin and produce fluid; in late autumn, cool dryness is the mainstay, and Apricot-Su San with the addition of maitake and sage is mostly used; sage and maitake soup is also a more commonly used formula.
