Any scientific experiments against bacteria? Anything observed in animal subjects or cultured bacteria? Bacteria with biofilms?
From the two links the only study (and not anecdotal evidence) is this:
"UCLA Medical School in the 1980s, Larry C. Ford, MD, documented over 650 different disease-causing pathogens that were destroyed in minutes when exposed to small amounts of silver."
I will have to check this study out if available. But how was it exposed to the silver? Because I use my antibacterial soap to kill salmonella off my cutting board but if I drank my antibacterial soap it wouldn't work the same way if I was infected with salmonella.
There is a lot of information on the internet regarding silver use bacteria that it is useful against. I for one have had my own experience as a result of stool testing. When my stool testing was done the company provides herbal and antibiotic constitutions that are directly tested on the sample to eradicate your particular strain. So for example for my strain X, silver was the highest rated constitution for getting rid of stain X wherein-which for strain Y it was olive leaf extract. So yes there is research out there regarding the use of silver as effective against many forms of bacteria and viruses. But as with all things, all silvers are not the same. You want small ppm's ionic silver for effectiveness.
