Insufficient lung Qi is explained from a TCM perspective, which often refers to the gradual weakening of the physiological function of the lungs. It often causes symptoms such as coughing and harming the stomach due to changes in weather from too cold to too hot. It poses a significant harm to patients, causing cough, excessive phlegm, pale complexion, white tongue coating, and so on. It can also cause some systemic symptoms, such as fatigue, chronic low fever, aversion to cold, and night sweats, etc.
