Faith is one thing.
Blind stupidity is another.

You need specific concentrations of Silver to kill various pathogens.

You cannot kill certain pathogens with 5-15 ppm. solutions- not even in a
Petri dish.

So you need a stonger solution to be effective. 

The only way to have a stronger solution is to use a protein to hold the
silver in above 15 ppm.. 
Then it becomes costly to produce, because you must then insure you remove
all the nitrates and nitrites that are byproducts of the processes.

Then you need to buy your silver from an licenced FDA research facility so
that you can be guaranteed that checkoff lists and GMP (Good Manufacturing
Processes) are being followed and signed off on a checklist, to insure
standards are being observed.

Ours is the only Silver that we know of in the U.S.A. (or the world for that
matter) that meets GMP Standards with a signed checkoff list that guarantees
you a quality product.

Some unscrupulous people are trying to make silver on their own outside of a
pharmaceutical and laboratory enviroment and without pressurized clean rooms
etc. and are harming individuals with contaminants in their silver, 

not to mention that their unstable preparation precipitates out and they are
just selling people water with contaminants from the manufacturing process
that would not be fit to be sold as drinking water in the U.S.- and we have
tested some silver manufacturer's brands and have found that to be true and
can attest that some would not even be fit to be sold as drinking water.
