Bronchiectasis is one of the common respiratory diseases,and its main clinical symptom is coughing up pus and spu-tum and(or)repeated haemoptysis.In Chinese medicine,it belongs to the category of"Lung Carbuncle",and its main pathological mechanism is based on the deficiency of lung and spleen,with phlegm-heat agglutination as the symptom,and its pathogenesis is characterised by the mixture of deficiencies and realities.Director Zhang Hua pays attention to the idea of"neutralisation"in formu-las,emphasises the clinical use of traditional Chinese medicine(TCM)prescriptions,integrates TCM classics with modem pharma-cology,and brings into play the unique advantages of TCM in the treatment of bronchiectasis in a combination of time and space.
