"Born with a silver spoon is his mouth" - silver has been used to cut infections. The Romans used large 'staples' made of silver to close battle wounds. Band-aids with silver infused on the pad are sold OTC.
Colloidal silver is a process of using tiny minute atoms of silver in water through electrolysis. You can make it yourself with a small current.
Silver really does work for infections. The OTC is too high and I suggest try make some at home. If it's cloudy - then the current is too high and you're making the silver bits too big for maximum surface area.
can drink it, put on wounds whatever - is just a little bit of silver.
