Evaluation of Quercetin Phytosome™ and Zinc in Supporting Subjects with Chronic Allergic and Non-Allergic Rhinitis

The aim of this study is to evaluate the possible benefit of Quercimmun (quercetin PhytosomeTM, a quercetin formulated as phospholipid Phytosome™ and zinc), in subjects with Chronic Allergic and Non-allergic Rhinitis, in order to alleviate symptoms. All enrolled subjects were supplemented with Quercimmun, 2 tablets/day for 60 days. The retrospective anamnestic and clinical-instrumental analysis of 36 enrolled subjects led to the subdivision of 3 groups: 12 mild chronic allergic rhinitis (according to ARIA), 12 vasomotor non allergic rhinitis, and 12 chronic drugs induced rhinitis (decongestive nasal therapy abuse). Monitoring was carried out at baseline and after 60 days of supplementation. The statistical evaluation of symptoms such as nasal obstruction, rhinorrhea, sneezing was carried out by associating a score according to the severity of the symptoms. Quercimmun was effective in alleviating symptoms after 60 days supplementation, confirming the beneficial properties of quercetin, proposing its use as a support aid in nasal-sinus disorders, especially of allergic origin.
