So I learned of a guy named Paul Karason who drank Colloidal Silver and put it on his body for health reason, and turned his skin permanently blue.
Apparently, Silver was used for thousands of years for its anti-bacterial properties until penicillin was developed. And, since people were prone to some weird things (the Romans used lead in everything likely to the point where it possibly poisoned their brains, and the Victorians were prone to some weird stuff fashion-wise, among others), my question becomes this: What if people drank/used colloidal silver the same way this guy did, for health benefits, to the point where blue skin became a common? Not a majority of people, of course, but a visible minority? How could this occur and what would be the effects on history?
