Great, thanks for the info Hver. I had always wondered if there were any risk of putting any bacteria, even beneficial in the sinuses since I wasn't sure if it was possible for them to somehow mutate into harmful form over a lengthy period of time. A crazy fear mainly perpetuated by when I asked others about trying this. If you're saying go for it though then obviously I was worrying about nothing.
So just to clarify there is a natural flora always present in the sinuses? Any idea if a certain form of probiotic is more dominant there? As well I was thinking of starting to irrigate daily with Colloidal Silver as I've never really tried that continually, and perhaps it would prove helpful? or would this just destroy my efforts using the bacteria?
