Silver destroys bacteria, viruses and yeast. It does so effectively that in lab studies, we've found that if you place a pathogen that can cause disease - from bacteria, from viruses, from yeast - add to it the silver, especially in the alkaline form, the molecular structure that's tetrahedral will destroy those pathogens in under 6 minutes.
In fact, a pharmaceutical test reported that we can destroy even MRSA. (That stands for Methicillin Resistant Staph Aureus.) That's the staph bacterium that causes flesh eating bacteria diseases; its eats your flesh. Even the resistant form, meaning bacteria that can't be killed by the drugs, the antibiotics can't even kill it; silver, in this form, can kill that in about six minutes.
In addition to staph and strep and e-coli, that causes food poisoning, salmonella causes food poisoning and pseudomonas aeruginosa, some of the most difficult bacteria and yeast like candida, are killed in under 6 minutes, using this form of tetrahedral molecularity strong silver, in an alkaline setting.
