Cough is a main symptom in pulmonary diseases. Generally, cough with a sound but without sputum is called "ke", while cough with sputum but without sound is called "sou". Since a cough usually with both sound and sputum, they are simply called "ke sou" clinically. Cough is a common symptom of various diseases as well as an independent disease. From the point of etiology, cough can be divided into two types, exogenous and endogenous. The former is caused by the six exogenous pathogenic factors invading the lung while the latter is due to dysfunction of the zang-fu organs leading to disturbance of the lung by endogenous pathogenic factors.
