Silver has no toxicity, no cumulative side effects, nor does it give rise to resistant strains, unlike some antibiotics, when used in its elemental, atomic (non-ionic) form. Over the last 20 years, there have been hundreds of references supporting the wide range of uses of silver on bacteria: such as e Coli, MRSA, streptococci, salmonella, legionella, and viruses such as HIV-1, hepatitis, herpes, norovirus, flu. See hundreds of references at www.colloidalsolutions.net
Even minute traces of metallic silver in atomic form are reported to have the unique property of in-activating several strains of bacteria, certain viruses, molds, fungi, protozoa parasites, and possibly prions (infective protein causing brain damage).
Research shows that silver is effective in concentrations of 0.01 to 0.04 ppm, and even 20 parts per billion (0.02 ppm). This is especially true when water is exposed to the silver for long periods of time. The solution can be used as a concentrated (20-50 ppm) remedy, taken in small doses, or it can be diluted in the drinking water supply at concentrations typically of 0.1 to 1 ppm.
