Dick and Scott, I hope you don't mind me combining both of your questions into one response since there is an overlap in subject matter.
It is generally accepted that you cannot make a stable EIS solution above 30 ppm. However, there is a method claimed to be able to make EIS as high as 500 ppm. It will of course be a dark color but it is also claimed that when sufficiently diluted, it will return to a light yellow color.( I would assume that at that point you could add a little H2O2 to produce a clear solution.) See: http://www.silverceramicsystems.com/CS16-5-3.html Recent Success at Concentrated CS Production Points Up Requirement of Very Pure, Distilled Water However, I don't know of anyone who has verified this information. An alternate solution to generating a high ppm silver solution is to generate a silver compound such as silver citrate or silver acetate. There are a number of silver compounds you can make but I picked these because they are on regular use. Silver acetate has been widely used in lozenges, chewing gums, etc. as a form of aversion therapy for smoking. Silver citrate is sold by several suppliers as a silver supplement or and as a germicide. I have made and used silver citrate, at concentrations as high as 600 ppm, but not silver acetate. Another silver compound in common use is silver chloride. I really haven't researched it and Marshall and Ode are who I would consider the experts on it. Will silver citrate or silver acetate turn you blue? There have been some instances of either compound causing argyria. The number of documented cases are small, unlike silver nitrate. My personal belief is that silver citrate is safe to take as long as you control your daily intake, same as you would EIS. The concentrated silver citrate is also very handy as a germicide/fungicide for external use. And as Scott asks, it is very convenient to take when traveling. Is it less/same/more effective than the usual EIS? The answer to this question is that I don't know. EIS has proven itself to be effective in nearly all instances where silver in any form would work. My personal belief is that silver citrate is as effective as EIS or CS. See the following study on silver citrate: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2590638/ Synthesis and Antimicrobial Activity of Silver Citrate Complexes Is it toxic in other ways? No. I have much more data but no time to present it. But perhaps what I have given will be sufficiently helpful. - Steve N _________________________________________________________________________________________________________ -----Original Message----- From: Scott Adams [mailto:[email protected]] Sent: Monday, December 07, 2009 7:42 AM To: [email protected] Subject: CS>Concentrated silver? My wife asked me the following and I would like to hear what others say... Can you make the silver concentrated, so I can take it traveling , put drops in a cup of water and drink it diluted that way? From: Richard Goodwin [mailto:[email protected]] Sent: Monday, December 07, 2009 7:17 AM To: [email protected] Subject: CS>silver citrate I have seen silver citrate mentioned a couple of times, and recently my DO told me that he uses a commercial silver citrate at 240 PPM to spray in his mouth and nose to kill viruses. What's the deal with silver citrate -- if you drink it, would it turn you blue? Is it less/same/more effective than the usual EIS? Is it toxic in other ways?
