Bronchitis is a common infectious disease of the lower respiratory tract, with cough and sputum as the main clinical manifestations, mostly caused by viral and bacterial infections. However, if there is cough, yellow sputum and fever, it is necessary to find out whether calcitoninogen and C-reactive protein are increased, that is, if the blood count is normal but other indicators are increased, antibiotic treatment can still be considered to shorten the course of the disease and relieve clinical symptoms as soon as possible. However, in general, bronchitis with normal blood count is not recommended to be treated with antibiotics, but can be treated with Chinese herbal medicine and western medicine to dilute the sputum. The Chinese medicine can be given to clear heat, resolve phlegm, and stop coughing such as snake bile and Chuanbei liquid, compound fresh bamboo leech oral liquid, and lung power cough combination, all of which can effectively clear heat and resolve phlegm to control bronchitis, and bronchitis blood routine is generally not treated with Western medicine, and can receive better results when given Chinese medicine treatment.
