According to Chinese medicine, the lung is the master of qi, and the rise and fall of qi in the whole body is related to the propagation and purification of the lung. When the lung qi is descending, the patient’s chest tightness, shortness of breath, coughing and coughing of phlegm are not obvious, and the patient breathes normally and freely. If the lung qi does not descend and instead manifests as qi reversal, coughing, coughing up phlegm, wheezing and even skin sweating will occur. In Chinese medicine, the lung is considered to belong to the five elements of gold, which corresponds to autumn, and the qi should mainly descend, which should bring the heat of nature down below the surface and complete the natural cycle of spring, summer, autumn and winter. If the lung qi does not descend, the weather will be very hot, leading to the prevalence of many infectious diseases and respiratory illnesses. Therefore, if the lung qi does not descend, coughing, coughing, chest tightness, wheezing, and even dizziness, insomnia, and excessive sweating all over the body will occur. In short, Lung Qi is mainly descending. If Lung Qi does not descend, TCM practitioners will give treatments such as purging and descending Lung Qi, tonifying the kidneys and nourishing Qi.
