You're right... I have nothing to lose... I can actually put H202 in my RinoFlow machine to get it into and around my sinuses without the burden of all that water, since it really causes me problems, and I have no real "symptoms" of sinus problems (runny mucus, colored mucus, congestions, etc) save for a little tenderness in my maxillaries and frontals.... Jeez -- they hurt right now, come to think of it!! But what is your ratio/formula for H202 to distilled water for irrigation purposes? And by "medical grade", do you mean the 3% solution? I already gargle with it (diluted) and put drops in my ears (full strength).... and I know it works there... Wow!! We should be on the sinus forum!! Is there even one on Curezone?? Hahaha!!! Anyway, thanks again for your insight, and I hope we aren't burdening others trying to focus on Candida!!
