Objective To investigate the main active components and pharmacological mechanism of Bushen Huoxue Decoction in the treatment of osteoporotic fractures by network pharmacology. Methods The chemical constituents of Bushen Huoxue Decoction were collected from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform（TCMSP）. The disease targets of osteoporosis were collected through the DisGeNET database. The predictive targets of Bushen Huoxue Decoction in the treatment of osteoporosis were screened by Venn diagram. Through gene ontology（GO）function and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analysis， the biological processes and signaling pathways of Bushen Huoxue Decoction in the treatment of osteoporotic fractures were preliminarily obtained. Cytoscape 3.9.1 software was used to construct the network diagram of Chinese medicinal components-disease targets-pathways. Through the analysis of topological parameters and the degree value as the investigation，the main active components of Bushen Huoxue Decoction in the treatment of osteoporotic fractures were obtained. The protein-protein interaction（PPI）network was constructed by online String 11.5 software，and the pharmacological mechanism of Bushen Huoxue Decoction in the treatment of osteoporotic fractures at the protein molecular level was obtained by topological parameter analysis. Results A total of 1 236 chemical components were screened out， including 72 predicted targets. It involves biological processes such as DNA transcription，translation，and even binding between enzymes，and intersects with KEGG signaling pathways such as diabetes， atherosclerosis and cancer. Conclusion Bushen Huoxue Decoction mainly through dehydrodiethylene glycol 4，Yangambin，Atropine，arachidonic acid，ellagic acid，stigmasterol，isorhamnetin and other major components acting on nuclear transcription factor p65，mitogenactivated protein kinase，estrogen receptor，tumor necrosis factor，cell tumor antigen and other protein molecules play a role in the promotion of osteoporotic fractures healing.
