Objective A variety of generalized bioinformatics techniques were used to explore the susceptible genes of allergic rhinitis (AR) from the direction of genetic epidemiology to promote the advantages of traditional Chinese medicine in the management of allergic rhinitis and contribute to the prevention of AR. Methods We first conducted Mendelian randomization (MR) and eQTL-based summary-data-based MR (SMR) to obtain genes related to genetic variation at protein expression level and gene expression level respectively, and the intersection was used to obtain the AR susceptible genes that had a greater impact on genetic variation, and the expression enrichment analysis was conducted using gene set data to explore the biological functions of genes. The key susceptible genes of AR were further selected by performed colocalization analysis and their drugabilities were analyzed. At the same time, molecular docking and Chinese medicine database were used to screen key AR susceptible gene-related active ingredients and potential intervention Chinese medicines. Results TLR1, NFKB1, TNFSF8, TAPBP, ITPKA and MAP1LC3A were identified as susceptible genes for AR. These gene expression was closely related to the function of Toll-like receptors, NOD-like receptors, phagocytes and other immune and inflammatory components, and they were also involved in the catabolism of hormones. TLR1 and ITPKA were the key susceptible genes and had the potential to develop targeted drugs. The propionic acid component of the active ingredient had the potential to prevent and treat allergic rhinitis. The main potential traditional Chinese medicines targeting the key susceptible genes were tonifying lung and spleen medicines. And “lung and spleen are treated together, qi and yin are in harmony” emerges as a pivotal strategy of compatibility in the prevention of AR. Conclusion Exploring the susceptible genes of AR and the potential intervention of Chinese medicine provides a new perspective for the study of AR, and realizes the clinical transformation of genetic epidemiology in the field of AR.
