To observe the effect of the Qi-Tonifying and Stagnation-Purging Method (Feixiantong decoction) on life quality of Idiopathic Pulmonary Fibrosis (IPF) patients. Methods：48 IPF patients were randomly divided into two groups，the treatment group treated with Feixiantong decoction and the control group treated with NAC for 3 months. We collected the score of SGRQ，6-minutes walk result and breathing difficulty score before and after the treatment，established a database and analyzed data with SAS 8.2. Results：Compared to control group，the treatment group improved significantly at the comprehensive assessment of SGRQ. There was significant improvement of the treatment group in terms of total score，symptom score，psychological status score about SGRQ after treatment，but the difference was not significant compared to the control group. The treatment group also showed significantly better effect in the 6 minutes walk test and difficulty breathing integral score. Conclusion：The patients with IPF can benefit from the treatment of the decoction of Feixiantong by relieving difficulty breathing，improving patient's quality of life and physical endurance.
