In the present study, we aimed to explore the mechanism of Salvia miltiorrhiza in the treatment of pathological scars (PS) by network pharmacology. The active ingredients and drug targets of Salvia miltiorrhiza were screened out through TCMSP database, the disease targets of PS in GeneCards database were obtained, and Venn diagram analysis on drug targets and disease targets was performed, and the intersection was used as the target of Salvia miltiorrhiza for the treatment of PS. Cytoscape software was used to construct a drug-ingredient-target-disease network diagram. A protein-protein interaction network was constructed through String website, its key protein modules and hub genes were screened with Cytoscape software, and GO and KEGG enrichment analyses were performed in DAVID database. Fifty-nine active ingredients, 138 drug targets, and 90 targets of Salvia miltiorrhiza for the treatment of PS were screened out. Core ingredients, such as luteolin and tanshinone IIA, were obtained. The hub genes, such as VEGFA, TP53, JUN, STAT3, AKT1, MAPK1, and PTGS2, and signaling pathways, such as HIF-1, TNF, MAPK, PI3K-Akt, and Jak-STAT, were screened out. Salvia miltiorrhiza might improve PS hypoxia, inflammation, and balance of proliferation and apoptosis of fibroblasts by regulating HIF-1, TNF, MAPK, PI3K-Akt, and Jak-STAT signaling pathways. Moreover, it had the characteristics of multiple centers, multiple targets, and multiple pathways.
