Objective: To explore the network regulation mechanism of Tanreqing Capsule (TRQC) on the treatment of coronavirus disease 2019 (COVID-19). Methods: Potential targets of the 19 major constituents in TRQC were predicted by the Swiss Target Prediction server and TCMSP database. Gene ontology (GO) function enrichment and pathway analysis of the targets were analyzed by Omicsbean analytic system and String 10 database. Finally, Cytoscape 3.6.1 software was used to construct the network pharmacology map. Results: A total of 19 compounds affected 68 pathways such as IL-17 signaling pathway, T cell receptor signaling pathway, arachidonic acid metabolism, cAMP signaling pathway, PI3K-Akt signaling pathway, influenza A, etc, by acting on 163 related targets, which associated with anti-inflammation, immune regulation, antipyresis, eliminating phlegm, relieving cough and asthma, analgesia, antibacterial and antiviral, and sedation. The network of \'compound-target-pathway-pharmacological action-efficacy\' was also constructed. Conclusion: The major constituents in TRQC, including scutellarin, baicalin, oroxylin-7-O-glucuronide, chrysin-7-O-glucuronide, forsythin, forsythiaside E, forsythiaside D, chlorogenic acid, caffeic acid, isochlorogenic acid A, ursodeoxycholic acid and chenodeoxycholic acid, may interfere with efficacy-related biological processes associated with antipyresis, eliminating phlegm and removing toxin by acting on key protein like TNF, EGFR, NOS3, PTGS2, IL2, GABBR1, MAPK14, ADRB2, REN, VCAM1, ACHE, PTPRC, etc.
