Asthma is a difficult evidence in medicine. As the saying goes: Surgery does not treat ringworm, internal medicine does not treat asthma. This shows the difficulty of treating asthma. In Western medicine, asthma is a manifestation of the decline of lung function; unless the function of the lungs is restored to normal, asthma will not improve. Western medicine to stop asthma is mainly drugs to dilate the airways and drugs to relieve airway inflammation. Similarly, Chinese medicine believes that asthma is not easily treated. To improve the efficacy of asthma treatment, we must understand the cause of asthma. In fact, asthma seems to be a symptom of lung disease, but in fact: all the five internal organs and six internal organs can cause asthma, not only the lungs. It is a prerequisite for the effectiveness of the treatment to distinguish the cause of asthma. Therefore, careful dialectical analysis is necessary. Song Xiuming, Department of Respiratory Medicine, Shanghai Shuguang Hospital West Hospital Every Chinese medicine practitioner can know how to treat asthma by dispelling phlegm and promoting lung. But clinically, attention should be paid to identifying the pathogenic roles of the liver, kidney, spleen, stomach, and the rushing veins in asthma. The spleen is the master of blood and blood control, and transports the qi of the middle jiao. The spleen must be wide and hollow to accommodate the blood. If the spleen itself is distended or constricted, it will lead to congestion of qi and blood and rebellion in the lungs, then asthma will be caused. At the same time, the spleen and stomach are dependent on each other, and if the spleen is not healthy, the gas in the stomach does not descend, or even reverts upward, which can also lead to asthma because the lung does not descend. The liver and kidneys reside in the abdomen, and their Qi is astringent, which can promote the downward flow of lung Qi. If the kidneys are deficient in qi, and the qi is injected into the rushing veins, the qi of the rushing veins will hold the stomach qi and rush upward to the lungs, which can also cause asthma. If the liver is not in balance with yin and yang, it will not be able to assist the kidney’s qi, or even force the kidney qi to expand, which will lead to the upward rebellion of the qi of the impulse vein, which is also a cause of asthma. Therefore, to treat asthma clinically, it is necessary to understand the vitalization of the five organs and their mutual regulation of production and control in order to be a good doctor.
