"Contains no animal proteins"

Here's a good way to get Argyria: commercial CS products from health food stores made, it would seem, with "proteins" just not animal proteins so it's...healthy? Silver Colloid must be made with pure distilled water and nothing else, no salts, and especially not proteins that can uptake and get "stuck" in tissue, causing the Blueskin Blues. For $20 you can get a constant current adapter from http://www.sotainstruments.com so anybody can make fine Silver Colloid for pennies a gallon versus the dollars per ounce at health food stores. The real lesson is that quality is easily controlled by you.
