A: One remedy I've long espoused is nasal irrigation, which can wash away allergens (like pollen) and excess mucus. When you experience a flare-up, fill a neti pot (a small, spouted dish) with saline water, then tilt your head to one side and pour it into the upper nostril. The water will then flush out of the lower nostril. Certain supplements can also help (consult your doctor before taking them): Bromelain may reduce inflammation inside the nasal passages, while some studies have shown butterbur to be an effective natural antihistamine.
