Abstract：Chronic cough belongs to the category of long-lasting and lingering cough in Chinese medicine. ZHANG Hong believes that Chinese medicine diagnosis and treatment of chronic cough is inseparable from the spleen. The treatment starts from two perspectives， namely “resolving phlegm from the spleen” and “reinforcing the healthy qi from the spleen”； prescription and medication should be carried out based on the consideration of different syndromes of cough. Banxia Houpu tang，Wendan tang and Sijunzi tang are commonly used in the treatment，which achieve good effects in clinical application.
