Abstract
The subject was a 70-year-old man who was suffering from productive cough after stroke. His symptoms were night cough, thick sputum production, reddened tongue and night sweat. The subject was diagnosed as having a deficiency of Yin, and was treated with Chungsangboha-tang(Qingshangbuxia-tang). A decrease in the severity of the subject's cough and sputum were observed, and $O_2$ saturation increased. In this case Chungsangboha-tang(Qingshangbuxia-tang) was effective on the patient with night cough, thick sputum production, reddened tongue and night sweat due to deficiency of Yin after stroke.
