Ordinary saline spray and wash solutions can cause irritation, burning and dryness. We added xylitol to our nasal saline solution to help soothe, moisturize and cleanse nasal passages and sinuses. The Xlear solution with xylitol more effectively thins the mucus to get rid of contaminants faster than other nasal rinse salt packets. Xylitol reduces bacterial adhesion and has longer lasting health benefits when compared to saline alone.
