Argyria is a rare bluish grey tint to the skin caused by ingesting fairly large amounts of silver. I think I read somewhere that there are, presently, only 70 known cases. The color comes from silver sulfide, which is produced by sulfur bearing materials in the body
Colloidal silver has powerful antiseptic qualities. I think that Silvadene is a CS salve. I heard it was developed for skin grafts. It kept the area moist and prevented infection. I used it once on a 2nd degree nitric burn that covered my lower leg. It was healed in just a few days. Probably, millions of people drink small quantities of CS daily. They buy it pre-made or they make their own (very easy to make). Google "colloidal silver" and you get a million hits. You can either buy CS making equipment or simply make your own.
CS can simply be made with the following:
Distilled water, the purist you can find. Walgreens is the best I found. If you have no Walgreens, buy a brand that says steam distilled.
About one foot of pure (I prefer 9999) silver wire, about 1/16" diameter, cut into 2, 6" pieces.
A water glass, about 8 oz capacity
1, 2, or 3, 9V batteries (see discussion below).
Two snap connectors for attaching the batteries in series (Radio Shack).
Two connectors with a snap plus a wire lead (Radio Shack).
Several wire leads with clips on both ends.
A milliamp meter (optional). Not necessary, but I like to watch the current. Also, it can be used to compare water purities. In general, the lower the initial current flow, the purer the water.
How to make CS.
(1) Fill a glass, to about 1" short of the top, with distilled water.
(2) One at a time, put the silver wires into the water, about 1/2" shy of the bottom. Fold the top of the wires over the edge of the glass. Pinch it so the wire is held flat against the inside of the glass. This works best if the top of the glass is flared out, like a beaker. The 2 wires should be on opposite sides of the glass.
(3) Batteries. The more batteries you use, the higher the current flow and the faster it will go. However, I prefer only using 1 or, maybe, 2 batteries. The solution goes through color changes and the lower current makes it easier to stop at the color I prefer (light yellow). Anyway, with more than 1 battery, snap them together with the connector(s), in series.
(4) Snap on the single snap connectors to the batteries and clip the 2 leads from the batteries to the 2 silver wires. If you use a meter, connect it in series with one of the leads from the batteries, using two wire leads. Battery to meter. Meter to silver wire.
(5) You are now making Colloidal Silver. In from 1 to 4 hours, it will turn a light yellow. That's where I stop, although many like it darker (it can get black). I'm more cautious, when I eat chemicals. The time depends on water volume and current flow.
(6) I drank about 2 teaspoons a day, diluted in water. Nasty, metallic taste. I had the feeling it was kinda like buying a device to keep the tigers away from your door. It must work, since you haven't had any tigers at your door. On the internet, you will find all sorts of wonderful medical claims for CS.
Notes: When you use very pure water and silver, the silver in the solution is a pure, metallic, silver colloid. If the water is impure or, if you dissolve certain salts in it (as in many of the commercially bottled solutions), the silver can form compounds. I have read that Argyria victims had used silver compounds, such as silver nitrate. On the internet, you can buy 999 or 9999 silver, both in 12" lengths. I buy the 9999. I think the safest CS is that that's made correctly at home. Read what you can find on the internet and try to weed out the BS. CS is also supposed to be good for animals and plants. It probably even works on dandruff, like Listerine claimed to do. Some say that the smaller the particle size, the better. The lower the current/water volume, the smaller the particle size.
