Bronchitis is a common lower respiratory tract infection with clinical manifestations of cough and sputum, and chest imaging suggesting increased and thickened texture in both lungs. It is believed that bronchitis belongs to the category of lung cough in Chinese medicine, which is mainly divided into external and internal cough. External sensations include wind-cold and wind-heat coughs, while internal injury coughs include coughs caused by phlegm obstructing the lung, phlegm-heat containing the lung, liver fire offending the lung, and deficiency of the lung, spleen and kidney. If the cough is wind-cold, we can give coughs to promote the lung, disperse cold and stop coughing, such as Tongxuan Liyu Pill. If the cough is wind-heat, clear heat, dissolve phlegm and stop coughing, such as Snake Bile and Chuanbei Liquid. If the cough is caused by Qi deficiency in the lung, spleen and kidney, consider giving drugs to nourish the lung, strengthen the spleen and benefit the kidney, such as Yu Ping Feng Granules, Ginseng and Bai Zhu San, Er Chen Tang and Jin Kui Kidney Qi Pill, which can effectively support the righteousness and dispel the evil, cure the disease and strengthen the root, reduce the recurrence of cough and improve the patient’s quality of survival.
