Always forget to sign in heh. Something else I wanted to mention is how they say H2O2 works. H2O2 is unstable and readily breaks down into H2O and O2 like this:

2H2O2 ----------> 2H2O + O2

So the net result is oxygen and water. Viruses are anerobic and when they are exposed to oxygen in any significant amount they die. With that said, I never found H2O2 to help with colds or flus.
