The invention provides a method for analyzing an anti-eczema effect target spot of traumatology based on network pharmacology. The method comprises the following steps: firstly, screening out seven representative active components through a SwisSADME platform, predicting by integrating SwisTarget Prediction, SEA and ChEMBL databases to obtain 367 drug targets, and analyzing to obtain 82 intersection targets; a PPI network is constructed based on an STRING database, and 10 core targets such as IL6, TNF and EGFR are screened out through topology analysis. GO / KEGG enrichment analysis reveals that the GO / KEGG is significantly enriched in the processes of IL-17 signal pathway, epidermal barrier repair and the like. Molecular docking verification proves that isofraxidin, scopoletin and verbenin are strongly combined with EGFR (epidermal growth factor receptor) targets. According to the method, a multi-component-multi-target-multi-channel synergistic eczema treatment mechanism of traumatology is systematically analyzed, and a theoretical basis is provided for preparation optimization.
