Mike, It is a shame that silver is considered toxic, it is not! Yes, it's considered a "heavy Metal" but it is not toxic. Ever heard of "Colloidal Silver"? (google) I would rather drink a glass full of "C. S." than get a shot of some antibiotic. It works on more pathogens than any antibiotic. It will kill bacteria, some viruses, molds, and yeasts. Yet it does no harm to the human or animal body. It has only one side efffect an d you have to drink it by the gallon to experience that. For lack of side effects it can't be beat, in moderate quantities.
A few years ago, my job took me into the NJ state library in Trenton.
I had access to the "Toxicology Reports" for each year and I studied them for any mention of toxic side effects. Again, the only thing that was mentioned was this effect (Turning the skin grey). However, one had to be consuming it in huge (Gallons) quantities. Remember, Silver was the metal of choice for surgeons implanting screws and braces into the body prior to the advent of stainless (surgical) steel. Google "Colloidal Silver" for a full explanation. I have been using it (as needed) since 1994.
