Objective: The preventive and therapeutic effects of the aqueous extract of Ficus pumila on COPD model rats were observed and its mechanism was also discussed. Methods: COPD model was established by intratracheal injection of lipopolysaccharide and smoking. Using the pulmonary function test, the level of related inflammatory factors detection in the BALF by ELISA, the blood gas analysis and HE staining for lung pathological observation. Results: The results showed that the indexes of the model rats were consistent with the pathological characteristic of COPD. The model group animals had obvious airflow obstruction, while the high dose of F. pumila aqueous extract group could significantly increase the levels of FVC, Fev0.3, PEF, Fev0.3/FVC （P2 and CO2 in the lungs of the model rats; At the same time, the high dosage of Ficus pumila aqueous extract can significantly improve the pulmonary ventilation function of COPD, and the effect was better than positive drug. Medium dose-, high dose aqueous extract group and positive drug group could significantly reduce the number of leukocytes （P
