Paul Karason, had an odd drinking problem that left him blue in the face.
Over a decade ago, Karason attempted to treat his facial dermatitis by coating his face with colloidal silver and...drinking it, too. Gross?
However, the silver concoction wasn't prescribed - Karason practiced self-medication, drinking nearly 10 ounces per day for fifteen years.
Not a good plan for Karason as as the liquid diet may have adversely affected the a 62-year-old who recently died of a heart attack.
Silver was replaced as a treatment by penicillin in the 1930s after the FDA discovered it caused argyria (a buildup in the skin and organs). Karason noted his financial troubles in a 2008 interview, as "people are reluctant to hire blue people."
The moral of the story? Don't drink liquid metal.
