Green Tea Not only is green tea a great source of antioxidants, which may help to reduce the inflammation associated with allegies, but drinking green tea also contributes to keeping you hydrated. Staying properly hydrated is one of the most important factors in keeping your nasal passageways clear, because if you’re dehydrated your nose will produce more mucus.

Spicy Food  If you’re not already a fan of spicy food, now just might be the time to start.  Foods like cayenne pepper, chilies, ginger, and curry powder promote the sinuses to run, this works to unclog those congested nasal passageways.  As if you didn’t need another excuse to eat Thai or Indian cuisine!
Probiotic yogurt  Yogurt containing probiotics, specifically the bacteria Lactobacillus acidophilus, may help to ease the symptoms of seasonal allergies. Probiotics act to change the types of bacteria found in your gut. In addition to strengthening your immune system, this shift in the profile of your gut bacteria appears to also reduce the inflammation associated with seasonal allergies.
