While 0.9% NaCl (isotonic saline) is conventional, sea salt water (SSW) mineral sprays enriched with complex trace elements are hypothesized to provide superior anti-inflammatory modulation. This study compared the efficacy of 0.9% NaCl and SSW mineral nasal spray on nasal mucosal eosinophil counts and clinical symptoms in patients with moderate-to-severe persistent AR.Methods: In this prospective cohort study, 30 patients with moderate-to-severe persistent AR were allocated into two groups (n=15 each): one group received 0.9% NaCl irrigation (20 mL twice daily), and the other received SSW mineral spray (0.15 mL twice daily). Clinical symptoms were evaluated using the Visual Analog Scale (VAS) at baseline, week 2, and week 4. Objective nasal mucosal eosinophil counts were assessed via nasal scraping and Papanicolaou staining at baseline and week 4.Results: Both groups exhibited significant reductions in nasal eosinophil counts and VAS scores by week 4 (p
