Silver, even in very small doses, is a poison to humans
If you are referring to the medical condition called argyria the presence of silver in the body poses no health rise. This condition is evidenced by the skin turning blue in color. So people with this condition look very strange. Silver and most of its compounds are only slightly toxic to humans. Silver has strong antibacterial properties. For decades newborns had a small amount of silver nitrate solution instilled into their eyes to prevent any venereal disease of the mother from causing blindness in the infant. Recent research has indicated that very small amounts of silver vastly increase the efficiency of many antibiotics. This may solve the problem of antibiotic resistant microbes.
