The cough is mainly characterized by a heavy, urgent cough with a tickling, dry throat. The cough is characterized by a heavy, rapid cough with an itchy, dry throat, thin, whitish phlegm and is accompanied by symptoms such as nasal congestion, runny nose, headache, heavy limbs and fever. The main reason for these symptoms is that the wind-cold evil invades the body, which mainly binds the muscular surface on the outside and affects the lung on the inside, so that the lung health is not promoted and the lung qi is depressed in the body and cannot be promoted, resulting in a cough with a heavy voice and shortness of breath. Secondly, it affects the throat and causes dry throat and itchy throat. In addition, the evil of wind and cold is depressed in the lungs, which will cause the fluid to not be dispersed properly and gather as phlegm, appearing as white and clear phlegm. At the same time, because the evil of wind and cold is bound to the surface of the muscles, symptoms such as nasal congestion and runny nose may appear.
