I imagine your question is directed at Reid Harvey; he mentioned in
February that he had used a Mexican silver product used for treating
salad vegetables, Microdyn.
Reid, do you think it is only the Microdyn that might be responsible, or
do you think working with silver played a part? You also mentioned
taking yellowish CS - how much of a problem is that thought to be
generally? Did you use distilled water exclusively in Bangladesh, Nepal
and Africa or locally available water (like the man in the US who made
his with tap water, and admitted it, but quite liked being bluish and
didn't really stop doing it.)
I remember when there was a lot of discussion of the silver water
filters; I often wondered how things went with them. Congratulations on
what you have achieved.

"Does CS cause Argyria - turning gray?"
Neville Mun said in October last:
Well CS might, but what we produce won't.
Everyone may have differing opinions on this one, so I'll get in with
mine <g>. What we make is (1) NOT colloidal silver {CS}, and (2) It
won't cause Argyria because it's predominantly Ag+ ions and not neutral
charged particles which are in higher numbers by ratio and as such won't
collect in tissue, besides it doesn't stay in the system long enough.
What we make in the kitchen is a predominantly Ionic Silver Solution,
and what particles there are, are far too small and in less quantity to
cause any cosmetic issue.
Of course I can't speak for Dave, or anyone else who may have consumed
or used large quantities for an extended amount of time, but if not
consumed in large volumes or for an extended period of time as far as
I'm concerned it won't cause Argyria. There has not been one case of the
consumption or use of our product reported by the FDA or our TGA as
having resulted in Argyria. Every report they waffle on about refer to
that product called 'CS' or 'Colloidal Silver', and most refer to silver
nitrates, silver acetates, solutions produced by people who are ignorant
or wilfully go against the correct production procedure, or a product
containing a form of stabiliser {usually higher ppm level products} and
a host of other 'stuff?' of which is not what we produce.
To recap: My opinion...NO, EIS {Electrolytically Isolated Silver} or a
'predominantly Ionic Silver Solution' will not cause Argyria.
and Steve G said:
Any time someone makes claims of argyria from colloidal silver there are
a number of things that you need to take into consideration before
concluding that CS was indeed the culprit.
1 - the term Colloidal Silver is sometimes used very loosely to describe
any sort of silver-containing liquid compound regardless of how it was
made. Only EIS, electrically isolated silver should be used.
2 - Did the person make their own CS? They must be careful to do it
right. The jars used should be rinsed with distilled water, then
emptied, then they can be filled with distilled water. Some people like
to put tap water in to save on the small expense, or perhaps to put in a
pinch of salt. Both of these strategies will result in a much quicker
batch processing time, but will NOT result in real CS as there will be
unpredictable silver salts created as a result. Paul Karason used salt
as a primer for years for his 'CS' which has resulted in a deep blue
skin condition. This stuff is not poisonous and IS effective and Paul
has not stopped taking it. I guess once you turn blue why bother to stop
taking that which keeps you healthy?
3 - How much CS/EIS is the person taking? Taking an ounce or so a day of
10 - 20ppm should normally be adequate for protection. Taking large
doses for serious illnesses such as lyme disease, syphilis, or other
terrible diseases may be warranted in the short run, but a maintenance
dose of 8 ounces or so a day seems to be overkill. Even properly
prepared colloidal silver over time can, I understand, cause argyria in
some people if taken long enough.
4 - Early warning signs. The first place a color change will show up
normally, is in the 'moons' of the fingernail beds. Get in the habit of
checking them out daily if you are taking a lot of CS. If they have
started to turn grey or blue, it is time to reassess what you're doing.
Finally, I have read some time back in this mailing list about a guy who
cured himself of a very serious late-stage 'fatal' illness (it may have
been syphilis) by using megadoses of some silver tincture preparation
over the course of several months. He regained his health, but turned
blue. Argyria is supposedly permanent, but according to his tale, he
reversed his blue skin condition by switching to pure EIS/CS for some
time. Later, to prove a point, he took the silver tincture and resumed
his argyria condition, then cured himself of it again via EIS/CS.
I haven't experienced this myself, and am not anxious to. It may be that
some people are susceptible to argyria and some are not, or that for
some, argyria IS going to be permanent, but can be reversed in some
cases. There is a lot of unknowns here.
John Simonsen posted this last December:
A recent article describes the mechanism of Argyria. The citation is:
ACS Nano (2012), 6(11), 9887-9899. I’ve copied the abstract from the
article here:
ABSTRACT The widespread use of silver nanoparticles (Ag-NPs) in consumer
and medical products provides strong motivation for a careful assessment
of their environmental and human health risks. Recent studies have shown
that Ag-NPs released to the natural environment undergo profound
chemical transformations that can affect silver bioavailability,
toxicity, and risk. Less is known about Ag-NP chemical transformations
in biological systems, though the medical literature clearly reports
that chronic silver ingestion produces argyrial deposits consisting of
silver-, sulfur-, and selenium-containing particulate phases. Here we
show that Ag-NPs undergo a rich set of biochemical transformations,
including accelerated oxidative dissolution in gastric acid, thiol
binding and exchange, photoreduction of thiol- or protein-bound silver
to secondary zerovalent Ag-NPs, and rapid reactions between silver
surfaces and reduced selenium species. Selenide is also observed to
rapidly exchange with sulfide in preformed Ag2S solid phases. The
combined results allow us to propose a conceptual model for Ag-NP
transformation pathways in the human body. In this model, argyrial
silver deposits are not translocated engineered Ag-NPs, but rather
secondary particles formed by partial dissolution in the GI tract
followed by ion uptake, systemic circulation as organo-Ag complexes, and
immobilization as zerovalent Ag-NPs by photoreduction in light-affected
skin regions. The secondary Ag-NPs then undergo detoxifying
transformations into sulfides and further into selenides or Se/S mixed
phases through exchange reactions. The formation of secondary particles
in biological environments implies that Ag-NPs are not only a product of
industrial nanotechnology but also have long been present in the human
body following exposure to more traditional chemical forms of silver.
In short, silver, whether ionic or nanoparticles, is absorbed into the
blood as silver ions attached mostly to proteins that contain sulfur. It
is then carried to all parts of the body. Once there it can form
nanoparticles once again upon exposure to light. It will also pull
selenium from the blood and together silver and selenium are extremely
insoluble, i.e. they stay there forever. Sunlight can photo-oxidize
these particles and your skin turns gray to blue. Generally what I have
read is it takes about 1 gram of silver accumulated in the body for the
risk of Argyria to become high. If your body retained 100% of 10 PPM
silver, it would take 100 liters to accumulate 1 gram. However, the vast
majority of ingested silver passes through the body, probably much more
than 90%. However, how much is absorbed and then deposited will depend
upon the individual’s body composition, diet, fluid intake, selenium
levels, etc. So the development of argyria is not easily predicted
except in extreme cases. Most of these are people working in industrial
settings where they are exposed to high concentrations of silver all day.

Well, if working on the water filters is involved in some bluish
tinge in some lights to some people but not yourself, I would wear
it as an occasionally possibly visible badge of honour, I think!
It's certainly not broken, but who knows what unguaranteed laser
treatment might do to fix something that might sometimes show - a
bit - or might not.
