Abstract:
Bronchiolitis obliterans is a syndrome of chronic airflow obstruction associated with inflammatory damage to small airway, which is an irreversible chronic obstructive pulmonary disease. Professor Zhao thinks that in this disease, deficiency of Yang is the root cause while stasis of phlegm and blood is the superficial cause. Therefore it is emphasized to perform treatment according to different stages: at the preliminary stage, differential treatment is needed; at the middle stage, reducing phlegm and removing stasis should be done; at the last stage, Yang must be strengthened. This method is proved to be clinically effective.
