Objective Bronchial asthma is one of the major chronic diseases that seriously affects public health worldwide. This study aims to identify new genetic targets for asthma by using GEO datasets and mendelian randomization (MR) methods, providing a basis for clinical treatment and mechanism studies. Methods The relevant datasets were obtained through the Gene Expression Omnibus (GEO) database, and after obtaining the data, the expression quantitative trait locus (eQTL) analysis and MR analysis were performed to identify potential targets; the functional roles and pathways of these genes were explored through gene set enrichment analysis (GSEA) and gene ontology (GO)/Kyoto encyclopedia of genes and genomes (KEGG) enrichment analysis, and the associations of the targets with relevant immune cells were explored through immune infiltration methods, and core genes were screened through Coremine medical database, which was a platform for medical ontology information retrieval. Coremine medical database to screen core gene-related therapeutic herbal medicines and generalize and analyze them, and finally set up an external validation set for confirmation. Results A total of 280 highly-expressed and 1 127 low-expressed genes were identified. MR analysis identified 12 core genes significantly associated with asthma, which includes PGAP3, FAM177A1, UGDH, AASDH, CREB1, ZNF429, CCNG2, SKAP2, ANKRD10, DR1, ISOC1, and LPAR6; Additionally, 67 traditional Chinese medicines (TCMs) were predicted, including Renshen (Ginseng Radix et Rhizoma), Wuweizi (Schisandrae Chinensis Fructus), Mahuang (Ephedrae Herba), Duzhong (Eucommiae Cortex), and Beishashen (Glehniae Radix), which were mainly involved in the categories of deficiency tonic, blood circulation and blood stasis removing medicines; The MR analysis results were consistent with those of the external validation set, which emphasized the reliability of the present study. Conclusion The present study screened and validated 12 potential asthma targets and predicted the related TCMs, which provides new insights into asthma pathogenesis, early screening, targeted therapy, and the clinical application of TCMs.
