Saw six ENT doctors, not cured. I was looking for fast, effective natural sinus cure. I spoke to an well know health expert who told me, "Nothing can survive in hydrogen peroxide after 20 minutes" An idea was born! This is fastest, easiest natural way that cured my bad sinus infection. I put sterilized water in neti pot, with a one tablespoon of hydrogen peroxide, some sea salt, and little bit of baking soda. I flooded my sinuses with this solution and then I hang upside down on my inversion board, for 20 minutes this is the key. I move my head from side to side to get the solution deep into my sinuses, I keep a cotton towel close by. I did this everyday for few days and I was cured. If you don't have an inversion board you can hang off the side of the couch. There is correct way of using neti pot so you get the solution into your maxillary sinuses. Please research it. I did.
