Methods The meridian tropism of each flavor in Qufeidu No. 1 prescription was searched and drug flavor-meridian tropism network was constructed; the potential active components of Qufeidu No.1 prescription were searched and screened on traditional Chinese medicine systems pharmacology database and analysis platform (TCMSP), and the ingredients which did not meet the above conditions but with pharmacological activity were supplemented by literature search. The component-related targets were obtained by TCMSP and Swiss Target prediction database, the disease targets of COVID-19 were acquired by Genecards database; DAVID database was used to annotate the KEGG pathway and analyze the functional enrichment of GO for the common targets of components and diseases and the target protein interaction PPI network and component-target-pathway network were constructed by STRING database and Cytoscape 3.5.1 software. Sybyl-x.v1.3 software was used to verify the molecular docking, and PyMOL software was used to plot the better docking results. Results The traditional Chinese medicine in Qufeidu No. 1 prescription mainly belongs to the lung meridian and stomach meridian. Through prediction and screening, 260 components and 85 targets were obtained. There were 18 core compounds including quercetin, β-sitosterol, caffeic acid, ginsenoside RH4, glycyrrhizin chalcone A and 55 targets including PTGS2, NOS2, Mapk14, PPARG and PTGS1. The PPI core network involved 11 targets such as GAPDH, TP53, mapk3, EGFR, TNF and IL6 and so on. Through GO enrichment, 352, 71 and 41 BP, MF and CC entries respectively obtained, 121 (P < 0.05) KEGG signal pathways were gained, of which 33 were core pathways, mainly related to hepatitis B, influenza A, PI3K Akt signal pathway, hepatitis C, HIF-1 signal pathway, TNF signal pathway, MAPK signal pathway, T cell receptor signal pathway, VEGF signal pathway, etc. Among them, vestitol and 3'-methoxyglabridin had good binding activity with ACE2; while glycalicacone, vestitol and caffeic acid had good binding activity with 3clpro. Conclusion The mechanism of COVID-19 treated by Qufeidu No. 1 Prescription is explained, providing certain scientific basis and reference for Chinese medicine in treating new crown pneumonia."/>
