I have been struggling with sinus problems for a few years now. I finally came across a great product that has been working really well. Its called Nasalcare. It is supposed to help with sinusitis, colds, and the flu. Its website states a few facts: It is an FDA-registered nasal irrigation system that is a drug-free and 100% natural sinus remedy. It’s hand-pumped for a positive continual irrigation. The irrigator is equipped with an air valve to maintain a positive pressure within the irrigator and has a one-way liquid valve to avoid backflow to maintain solution purity. The solution is sea salt based and buffered with bicarbonate, sodium citrate and citric acid. In addition, Aloe extract is added to alleviate nasal dryness. Also, NasalCare® has been named the “Best New Product” at the 2010 ECRM Cough & Cold Allergy Conference this past March. I hope this helps others as it helped me!
