I have not worked up the courage to do this yet, but I was thinking about using a weak solution of Miracle-Mineral-Supplement (like two drops) in a Neti pot. I have had good luck clearing my sinuses with the Neti Pot, but I have had one sinus infection after another all year. I suspect it is all one infection that just flares up, but even a round of pennicillian last spring did not bring lasting results. Neither has oil of oregano, olive leaf, iodine, or H2O2 (Hydrogen-Peroxid) (which will never come near my nose again in this life). Colloidal Silver helped a little, but the infection keeps coming back.
