Antiseptic

Acting as a catalyst, it reportedly disables the enzyme that one-celled bacteria, viruses and fungi need for their oxygen metabolism. They suffocate without corresponding harm occurring to human enzymes or parts of the human body chemistry. The result is the destruction of disease-causing organisms in the body and in the food.

Here is an exerpt from an FDA research paper. I believe the report says 650 organisms.

"And now it's (colloidal) silver that is finding wholly new uses as a wonder in modern medicine... perhaps it soon will be recognized as our mightiest germ fighter." (Science Digest, March 1978.) Silver is considered to be one of the most universal antibiotic substances known. Jim Powell reported in the Science Digest article quoted above, that an antibiotic kills perhaps 7 different disease organisms, but silver kills some 650. Resistant strains fail to develop. Moreover, silver is non-toxic!

An article in Science Digest (March 1978) titled Silver, Our Mightest Germ Fighter was the original source to conclude that colloidal silver kills over 650 disease-caused conditions. The authors called colloidal silver the best all-around germ fighter we have.
