Effects of AkPharma's Calcium Glycerophosphate Nasal Spray Wash

Subjects will be screened for inclusion and exclusion criteria and consented if they fit the same criteria. They will be instructed on keeping a nasal diary of symptoms "runny, itchy, congestion, sneezing, voice changes and throat clearing". They will have blood drawn for allergy testing. After a 1 week run-in, subjects will return their diary. If they still qualify based on the diary they will have baseline labs drawn and baseline breathing test (Spirometry) performed. They will also have a nasal wash and specimen collection performed. They will be instructed on use of the nasal wash. There will be three more weekly visits before study conclusion which will include diary submission, Spirometry and nasal wash and specimen collection. On the final visit blood will again be collected as well.
