ABSTRACT
Korean red ginseng (KRG) is reported to have anti-allergic properties, including beneficial effects on asthma and atopic dermatitis. However, its effect on allergic rhinitis has not been studied extensively. This study examined how KRG affected allergic inflammation of the nasal cavity in an allergic mouse model. A total of 40 Balb/c female mice were divided into four experimental groups according to treatment and allergic state group 1 (G1), saline only; group 2 (G2), ovalbumin (OVA); group 3 (G3), OVA+KRG; and group 4 (G4), OVA+dexamethasone. Serum IgE levels were significantly lower in the KRG treatment group (G3) than in the allergic group (G2). However, serum IgG1 levels did not differ between G2 and G3. In the nasal lavage fluid, IL-4 and IL-5 levels were significantly lower in G3 than in G2 (p<0.05). H&E and Luna staining revealed that the eosinophil count was lower in G3 and G4 than in G2 (p<0.05). Immunohistochemical staining revealed that there were fewer IL-4-, IL- 5-, and MUC5AC-positive cells in G3 and G4 than in G2 (p<0.05). These results indicate that KRG reduces the nasal allergic inflammatory reaction in an allergic murine model by reducing Th2 cytokines.
