I've tried so many things that people praise though and they never work. Colloidal silver being one of them, it did nothing for me. I made it home made and used 8-10oz per day for several months, half through an enemas and half drinking, and it didn't do anything. Made it to about 10ppm.
MMS is another one of those things people praise a lot but I'm highly skeptical of trying. But I guess you don't know until you try it.
