Immunohistochemistry further shows that the protein content of PTGS2 and MAPK3 in the administration group is significantly reduced, and it can reduce the serum inflammatory factor TNF-α, IL-4, and IgE, increase the concentration of anti-inflammatory factor IL-2, by regulating neuroactive ligand-receptor interaction, Th17 cell differentiation, VEGF signaling pathway and other biological pathways play a role, the volatile oil of C. minima has a significant effect on the treatment of allergic rhinitis and is multi-target and multi-channel. This evidence concerns the gene TNF and allergic rhinitis.
