I have lots I could say about Colloidal Silver - both pro and con. I haven't answered because I received numerous messages ranging from "please don't express your views here" (I don't express "views", I relate supportable scientific and medical facts) to quite vulgar and threatening ramblings about being a "Big Pharma" shill, etc. I've surveyed this "open" forum, it's all the usual insults continually directed towards anyone with any scientific knowledge who challenges what's put forth here. People must keep electronic libraries of giant canned texts to dive-bomb interlopers with! Have you ever heard of the "Gish Gallop"? I thought I could perhaps contribute and make helpful comments based on 40+ years of experience in direct health care as both an RN and as a laboratory scientist. It seems I don't mix well with the alternate reality here. I've never experienced animosity like here on any other health related forum I've contributed to.
