Yes its antiviral, antifungal and antibiotic. You can put it in a green aquarium and watch it clean out. Then you have tetrasilver thats even stronger..they used to use it as a pool cleaner and also in wound ointments. There is a patent on it curing cancer, but Ive never seen studies that prove it. In the old days they would put a silver coin in milk just to get it to last longer. Its fun watching videos of people putting it in fishtanks full of algae..a couple of days and its clear-the same effect as bleach, but minimal toxicity to human cells. Doctors who dispute these things are merely showing their ignorance of medicine and history.
