"Silver"
Some interesting highlights from Health Canada's report on silver...
- Silver is used "in the manufacture of fungicides"
- Common foods contain silver, "several hundred milligrams per kilogram, have been recorded in mushrooms"
- "wheat flour and bran are reported to contain 0.4 and 1.0 mg/kg dry weight, respectively"
- "molluscs 0.1 to 10 mg/kg dry weight"
- "meat (beef, pork, mutton, and lamb) 0.004 to 0.024 mg/kg wet weight"
- "Silver is used to treat potable water for Swiss ski resorts, German breweries, soft drink bottlers, British ships, Shell Oil Company tankers, drilling rigs, and over half the world's airlines. Concentrations of 0.1 to 0.2 mg/L of silver are sufficient to ensure antimicrobial action."
- "most ingested silver is rapidly excreted and that little is absorbed"
- "Daily intake of silver (from food) was found to be 0.088 mg" (88 mcg)"
- "daily intake of silver from food and water is considerably below the level at which adverse effects would occur."
- "the injection of 1000 mg of silver as silver arsphenamine" produced Argyria (i.e. 1,000,000 mcg produced blue skin)
Advanced Silver is sold for internal use as a dietary supplement.
