Objective Analysis of clinical trials of clearing heat and removing phlegm combined with routine Western medical treatment in treating chronic obstructive pulmonary disease by meta analysis. Methods The randomized or semi-randomized controlled studies involving treatment of COPD with clearing heat and removing phlegm combined with routine Western medical treatment were searched and identified from CNKI， Wanfang Data， VIP， PubMed and Embase. According to Cochrane methods， two reviewers independently screened literature， assessed methodological quality， extracted data， and analysis by RevMan 5.2 software. Results A total of 8 studies， including 693 cases of patients （346 in experimental group and 347 in control group） were included， The results of Meta analysis suggest that： Clearing heat and removing phlegm combined with routine Western medical treatment can significantly improve the clinical symptoms in patients with chronic obstructive pulmonary disease[OR=5. 36， 95%Cl（2.94， 9.78）， （P<0.00001）]； PaO2： [WMD=8.14， 95%Cl（1.31， 14.97）， （P<0.05）]. PaCO2： [WMD=-7.33， 95%Cl（-13.75， -0.92）， （P<0.05）]. FEV1/FVC：[WMD=2.75， 95%Cl（0.85， 4.65），（P<0.05）]. Conclusion Clearing heat and removing phlegm combined with routine Western medical treatment in treating chronic obstructive pulmonary disease is effective. Problem and Prospect：The results of the previous research and the trial quality are low， the experiment potential publication bias. We cannot make a final conclusion of the effectiveness based on this Meta analysis. High quality trials with large sample size and multi-center are needed to verify its clinical effects.
