The poster did not ask about other methods, they asked only about colloidal silver.
If they do look into MMS, I suggest they also look at all the posts in CureZone by those who said MMS did not work for them and the side effects they experienced. Although it is not a place I would recommend anyone hang out for long, the MMS debate forum could be enlightening too.
I took a very long look at MMS and at Jim Humble as well. In the end, I decided that I could not recommend MMS, except perhaps as a last resort. I don't usually warn against it, as it does work for some people, but I am wary of long term effects and in almost every instance I think there is something equally or more effective and safer. Colloidal silver, for example.
