Treat cough and stop wheezing (zhi ke, ping chuan)

Stop cough and wheeze from both exterior and interior conditions, depending on the herbs with which they are combined, by redirecting Lung qi downwards, transforming phlegm and moistening the Lungs. Common examples include xing ren (Prunus armeniaca) and pi pa ye (Eriobotrya japonica) which especially benefit externally-contracted coughs with wheezing and cough with difficulty expectorating, respectively.
