Nasal Irrigation - Saline
"Liquid-based nasal irrigation (NI) is performed using a nasal irrigation cup (neti pot), a simple hand-held vessel that uses the force of gravity to gently irrigate the user's nasal cavity. Subjects will be requested to perform NI twice daily. The subjects will prepare the saline solution by themselves using the study-provided kit which will include packets of salt powder and the neti pot; subjects will dissolve the powder in lukewarm tap water to achieve a 2% buffered saline solution. The solution is then delivered to the nasal cavity using neti pot."
Nasal Irrigation - Xylitol
"Liquid-based nasal irrigation (NI) is performed using a nasal irrigation cup (neti pot), a simple hand-held vessel that uses the force of gravity to gently irrigate the user's nasal cavity. Subjects will be requested to perform NI twice daily. The subjects will prepare the Xylitol solution by themselves using the study-provided kit which will include packets of Xylitol powder and the neti pot; subjects will dissolve the powder in lukewarm tap water to achieve a 5% Xylitol solution. The solution is then delivered to the nasal cavity using neti pot."
