I had chronic sinus infection for three years. I saw three ENT and had sinus surgery which resulted in scar tissue and option of another surgery to remove scar tissue.
I can across a study on Serrapeptase. In a double blind study, 97.3% success rate in the serrapeptase group as compared to a 21.9% in the placebo group. That is pretty amazing results! Take serrapeptase religiously for two weeks to a month.
I took one three times a day on an empty stomach for a little over month. Cured!
