Interesting site, I have not seen it before. Unfortunately there is
little or no documentation on the cases, making it impossible to follow up
on them to verify the reports. There are a few interesting things I would
like to comment on though:
Argyria Cases Caused by the Use of ENIVA Colloidal Silver: 2
ENIVA markets a high PPM stabilized colloidal silver compound, and claims
that argyria is impossible to acquire from their product due to the fact
that there are no "silver particles" present in their product. Their
aggressive marketing campaigns have lulled at least one unsuspecting user
into a false sense of safety based on the ignorance of their marketing
team, and the unscrupulous character of their business practices.
----------------------------------------
There is something wrong with these statements. First there is no such
thing as a high PPM stabilized colloidal silver, true colloidal silver has
a limit of about 20 to 25 ppm. They claim there are no silver
particles. Well the definition of colloid means particles suspended, so
they are contradicting themselves right there. Lastly, it is silver ions,
such as silver salts which cause argyria, particles not only cannot cause
it, but provide nucleation sites for salts so that they can be captured
without causing argyria. That is particles tend to be a prophylactic to
argyria development.
## I am not aware of any PPM limit for "true colloids"
Making [nice looking and reasonably stabile ] "EIS" at over 25 PPM is
dicey to be sure, but not impossible.
