Objective: To study the QingFeiPaiDu Decoction (QFPDD) in the treatment of Corona Virus Disease 2019 (COVID-19) bioactive ingredient and its potential mechanism. Methods: Combined with the clinical symptoms of COVID-19 patients, a "component-target-disease" network model was constructed based on the network pharmacology method, and potential active components, targets and molecular mechanisms of QFPDD for COVID-19 were screened out through topology parameter analysis.Results: We collected 376 active ingredients of QFPDD from the database, and 18833 potential anti-novel coronaviruses (SARS-CoV-2) targets were analyzed and screened. The principal targets involved PIK3CA, PIK3R1, APP, SRC, MAPK1, MAPK3, AKT1, HSP90AA1, EP300, CDK1, etc. We obtained 574 GO entries by Gene Ontology enrichment analysis and obtained 214 signal pathways with P
