I have the colloidal silver spray (18-22 PPM) for my nasal polyps. Now, it is not working. I used to spray a Flonase - you have seen this on TV commercial. I hate the Flonase because it usually blocks my nose for a week. I cannot find another way to kill the polyps without a surgery. It makes me crazy. A couple of years ago, my doctor removed them in the operation room, and he didn't finish it because he was careless. He is full of asshole. Do you know alternative medicines that might work for me and others who have the same problem? Last year, I read about a Hydropgen Peroxide on the internet - a forum saying that it helped them to eliminate their nose-allergy for one year without using any medicine. Now, I don't remember the name of that forum. Maybe, this information seems too true but too tricky cuz it is just a forum. If I use Tea Tree Oil, I don't like it because of the scent that blocks my nose for one week. ggrrrr. Darn it. The QXCI machine usually works for me, but the service is not cheap, and it takes 45 minutes for me to drive there for my appointment. Well, I hope that you know how to get rid of that damn polyps. Let us know about it. Thanks.
