Here's a helpful how to video demo of the NeilMed Sinus Rinse and Neti Pot for curing Allergies and Sinus. I have used this for quite a few years and it and really works. Instead of taking meds, I found this is a very good alternative. It have saved me from my allergy filled wasted day and gave me my life back. Remember distilled water sterile water is recommended because many places may not have a chlorine in the water. I prefer the neti pot over the spray bottle but my other have loves the squirt bottle instead. You use 1 nasal solution package each time and it really helps. It may not always be the cure 100% of the time then you can do the meds or nasal sprays but it's really does rinse out the inside of the nasal passage. It also works to help cold viruses.
