Argyria: What happens

Too much of a good thing

Scientists have known for years argyria — a condition that turns the skin blue — had something to do with silver. Brown scientists have figured out the complex chemistry behind it.

Ingesting silver — in antimicrobial health tonics or for extensive medical treatments involving silver — can cause argyria, condition in which the skin turns grayish-blue. Brown researchers have discovered how that happens.  The process is similar to developing black-and-white photographs, and it's not just the silver.
