Hi Fullset, thank you for your post. I am fascinated by H2O2 (Hydrogen-Peroxid) but it sounds like something I would try on myself if I had lung problems, but not on my daughter - yet anyway, although I will do a lot more research. I think the reason ginagirl suggested Lugol's with Vit C was because I can't source straight potassium Iodide here in New Zealand so by mixing the high dose Lugols with juice and Vit C then it turns it to Iodide anyway which apparently works better on the lungs. But yes I am on a mission to find the solution so I am going to try it. :-)
