Abstract: Professor Wang Ji'an emphasizes that there is difference between dispersing and clearing in pulmonary diseases, which helps lung-qi to go upward or downward. Clearing and warming must not be excessive in order that the differentiated treatment can be carried out in time. The reinforcing and reducing should be given properly to eliminate the evil and secure health. The drugs should be mild in nature and the course should be short because the organs are delicate. The organs are inter-related, so the treatment for pulmonary diseases should not be limited to lung, and spleen, stomach and liver should be considered. For patients whose lung-qi can't be dispersed, the treatment should be based on coldness or heat: for patients with wind-heat invading the lung, the lung-qi should be cleared, while for those with wind-coldness invading the lung, the lung-qi should be warmed to disperse. For the patients whose lung-qi can't be cleared, there are 4 ways to clear the lung: descending lung-qi, relieving spasm, clearing organs, and reducing lung to relieve asthma. Prof. Wang Ji'an believes that the treatment for measle pneumonia should focus on dispersing, clearing and relieving. Clinically, measles usually is a disease involving both weifen and qifen, and involving qifen and yingfen, but it rarely involves xuefen, so the treatment focuses on the causes: to remove the evil and regulate qi in order for the heat-evil of yingfen to be eliminated. The treatment for pertussis can be based on liver, and the well-known prescription——Xuanci Baibu decoction——has significant effect on spasm and cough of pertussis and pertussis-like syndrome.
