• With Sang bai pi to clear the Yin and Qi divisions, to effectively clear heat and drain fire from the Lungs, eliminate deficiency fire damaging the Lungs, stop cough, and calm asthma. For the following indications, the combination is found in Xie Bai San:
– 1. Cough and asthma with expectoration of yellow, sticky, and thick phlegm, fever and thirst due to Lung heat.
– 2. Cough accompanied by evening fever or low but persistent fever with skin which is warm to the touch due to deficiency heat damaging the Lungs.

In case of deficiency heat, add Zhi mu and Mai men dong.
