Preliminary Clinical Effect Evaluation of Resveratrol in Adults with Allergic Rhinitis.



Resveratrol is a natural, nonflavonoid polyphenol, exerting anti-inflammatory activity. It has been reported that resveratrol, together with carboxymethyl-β-glucan, can reduce nasal symptoms in children with allergic rhinitis (AR). In this study, the effect of resveratrol on nasal symptoms in adults with AR was investigated.


We conducted a placebo-controlled, double-blinded study. One hundred and fifty-one adults (aged 18-60 years) with severe persistent AR were divided into a placebo-treated group (n = 50), a positive control budesonide-treated group (n = 50), and a resveratrol-treated group (n = 51). They were then treated with 2 sprays (100 µL/spray) in each nostril 3 times/day for 1 month. Nasal symptoms including obstruction, itching, sneezing, and rhinorrhea, and the levels of IgE, IL-4, TNF-α, and eosinophils in the blood were assessed at baseline and after treatment.


Adults treated with resveratrol or budesonide achieved a significant reduction in nasal symptoms compared to the placebo-treated group. The resveratrol treatment significantly decreased the IgE, IL-4, TNF-α, and eosinophil levels in the blood. In addition, the resveratrol treatment was found to improve the quality of life of adults with AR.


Our preliminary study showed that intranasal resveratrol is capable of significantly improving nasal symptoms in adults with AR.
