Methods Database of Experiences of Contemporary Famous Chinese Medicine Doctors in Treatment of Lung Disease and Database of Journal Articles on Chinese Medicine for Lung Disease were searched and the papers on diagnosis and treatment of bronchial asthma by famous Chinese medicine doctors were screened. The symptoms and syndrome types of bronchial asthma were analyzed with the methods of frequency-factor analysis

cluster analysis and two element Logistic regression analysis. Results Totally 2459 papers met inclusion criteria were found out from the databases. Syndromes with the frequency ≥3. 0% were syndrome of phlegm-heat congesting lung

syndrome of phlegm-dampness blocking lung

syndrome of Qi deficiency of lung and spleen

syndrome of Yang deficiency of lung and kidney

syndrome of Qi deficiency of lung and kidney

syndrome of kidney-qi deficiency

syndrome of lung-qi deficiency

syndrome of cold-phlegm obstructing lung

and syndrome of deficiency of both Qi and Yin of lung. Factor analysis and cluster analysis were made on symptoms. Five meaningful symptom clustering combinations were obtained. Combined with clinical practice

the authors summarized that common syndromes of bronchial asthma were syndrome of phlegm-heat congesting lung

syndrome of wind-cold attacking lung

syndrome of Qi deficiency of lung and spleen

syndrome of lung-qi deficiency

and syndrome of deficiency of both Qi and Yin of lung.Main symptoms and secondary symptoms of each syndrome were obtained. Conclusion Clinically

the common syndromes of bronchial asthma are syndrome of phlegm-heat congesting lung

syndrome of wind-cold attacking lung

syndrome of Qi deficiency of lung and spleen

syndrome of lung-qi deficiency

and syndrome of deficiency of both Qi and Yin of lung. Each syndrome had its symptom specificity.
