Viralis RX If you do not use some type of water saline solution to wash your sinus, regular water feels like it is burning your brains out. It hurts. You must use about 1/2 teaspoon of non-iodized salt to every 8 ounces of room temperature water and some people add 1/2 teaspoon of baking soda to that as well. I just Men Health used the salt. Now I use Med-Systems packets just because they are faster. I have doubts they work any better. The water should be distilled or filtered water. I did not use distilled or filtered water and still don't but I should.
