Thanks! My daughter gets bad sinus infections and the GSE (I also add Xylitol) in her rinses have made a big difference. She had never been able to get rid of an infection without antibiotics and was on so many antibiotics last year that I decided to give it a try and the difference was amazing! I am not suprised that a doctor would say that saline would be enough for a sinus rinse, saline was very helpful for my daughter but not nearly enough to get rid of the infection. Without this mixture she would no doubt have spent another winter on antibiotics (last winter she was on them for all but a few weeks) and felt sick and crappy the entire time, but thankfully I think we found a good fix.
Also, I have found lots of info online (for what it is worth!) that says GSE is effective against PA, SA, MRSA,and possibly B. cepacia (haven't found much info on it, haven't looked for much either). I don't depend on it as an antibacterial but figure it is an inexpensive, safe and easy way to take some extra measure.
