Combat fall allergies with a nasal spray containing xylitol. Recent research found that patients had better results using natural products. In three weeks patients showed a 36 percent improvement in their peak airflow and a 25 percent reduction in their SNOT score—the measurement of a persons comfort level when they have allergies. The lower the score the better. Xlear Nasal Wash gently cleans and soothes sinuses and nasal passages, promoting sinus health.
