Bronchiectasis is a refractory chronic airway disease characterized by chronic cough and phlegm production. Airway mucus hypersecretion is one of the important causative factors for acute exacerbation of bronchiectasis. Thus， reducing airway mucus secretion during the stable phase of bronchiectasis is the key to the treatment. Phlegm-dispelling therapy is commonly used in modern medicine， which， however， fails to radically reduce mucus secretion. At the moment， it is difficult and urgent to find an intervention that can improve the quality of life of patients and reduce the recurrence of disease during the stable phase of bronchiectasis. Chinese medicine shows remarkable efficacy in reducing airway mucus secretion. Nonetheless， there is a lack of research on the airway mucus hypersecretion of bronchiectasis， and no registered research outcome is available. Traditional Chinese medicine boasts a lot of experience in the treatment of phlegm. It combines clearing and tonifying methods and identifies Yin and Yang and internal organs， thus being advantageous in the treatment of airway mucus hypersecretion of bronchiectasis. Therefore， it is an important topic to improve the effectiveness of Chinese medicine on airway mucus hypersecretion of bronchiectasis by focusing on the "generation"， "transformation" and "excretion" of phlegm.
