Allergic rhinitis (AR) is a growing global health concern. Despite being non-fatal, it has a detrimental effect on people′s quality of life and poses a significant economic burden. In this study, we aimed to evaluate the anti-allergic effects of aurantio-obtusin against ovalbumin-induced murine model of allergic rhinitis. Aurantio-obtusin was administered to rats orally after sensitization to ovalbumin. Results of the study suggested that aurantio-obtusin causes a significant reduction in nose rubs and sneeze as compared to the vehicle-treated disease control group. The aurantio-obtusin treated group showed a dose-dependent significant reduction in serum TNF-α, IL-4, and IL-6 levels as well as histamine levels in the nasal mucosa. Addnl., it decreased neutrophil and eosinophil numbers in blood of AR rats′. In the nasal tissues of the vehicle-treated rats that were subjected to an OVA challenge, the histol. of the nasal mucosa of AR rats revealed aberrant histol. changes. A variety of histol. abnormalities, including vascular congestion in the nasal mucosa, substantial inflammatory cell infiltration, and obvious alveolar wall edema were present. In the rats treated with aurantio-obtusin, these characteristics were reversed. Collectively, the findings suggests that aurantio-obtusin could be used to enhance current AR treatment approaches.
