What Researchers Say -- Nano Silver

Colloidal silver-Safety aspects

“The silver doesn't harm human tissue or kill off the good bacteria in the intestine the way antibiotics and other medications do."
-- Dr. Jonathan Wright, MD

In "Colloidal Silver", a booklet produced by the Association for Colloidal Research, it is reported that: "Medical Journal Reports and documented studies spanning 100 years indicate no known side effects from oral or IV administration of properly manufactured Colloidal Silver in animal or human testing. There has never been a reported reaction with Colloidal Silver to any prescription medication.”

Alexander G. Schauss, Ph.D. Director, Life Sciences Division John Hopkins University The Environmental Protection Agency's Poison Control Center reports no toxicity listing for Colloidal Silver;” it is therefore considered harmless in any concentration. However all of the silver salts are identified as toxic, although the only adverse effect noted is Argyria. Therefore the concern is with silver salts not Colloidal Silver”.
Colloidal Silver a closer look: By Peter A. Lindemann

"Silver is one of the most universal antibiotic substances. When administered in the colloidal form, it is for all practical purposes non-toxic. Silver has been proven to be effective against hundreds of infectious conditions. It has tremendous anti-microbial power; the history of safe and successful colloidal silver use is extensive, and the number of current health professionals and individuals that successfully utilize colloidal silver to reduce the length and severity of infectious disorders is growing exponentially."
Zane Baranowski, CN

“Colloidal Preparations of Silver in Pharmacy,” British Medical Journal, February 1923: “Pure Silver is entirely non-irritant. In tests at very high concentrations, it has been shown repeatedly that the rapidly exerted disinfectant action is of considerable therapeutic value.” (ref The only answer to cancer by Leonard Coldwell, Chapter 19)

"Use of Colloids in Health and Disease." Colloidal silver has proven particularly effective in cases of intestinal troubles. Dr. Henry Crooks found that "silver in the colloidal state is highly germicidal, quite harmless to humans and absolutely non-toxic. Rather than in a chemical compound, the silver in the colloidal state may be applied in a much more concentrated form, with correspondingly better results. All virus, fungus, bacterium, streptococcus, staphylococcus, and other pathogenic organisms are killed in three or four minutes upon contact. There are no side effects whatsoever from the highest concentrations."
A closer look at Colloidal Silver By Peter A. Lindemann,

"Common substances like table salt and aspirin are harmless with normal use, but excessive intake can become toxic and even life-threatening. With normal responsible usage, silver supplements are entirely harmless to humans."
-- Jeffrey Blumer, M.D., Ph.D., director of the Center for Drug Research, former director of the Greater Cleveland Poison Control Center

A recent paper by Das et al. provides the remarkable datum that some 275,000 kgs of edible silver foil are consumed every year (in food) in India. No known adverse health effects have ever been recorded.
