In ancient Rome, silver nitrate was used as a medicine. The Pharmacopoeia published in ancient Rome in 69 B.C. In 78 A.D., Pliny the elder, in his natural history, described silver's properties in this way: "it has therapeutic effects Especially in promoting wound healing
The wealthy Romans used silver wine glasses and silver utensils every day, not only because silver was a symbol of wealth: aristocratic families used silver spoons to feed their babies, which they believed could get rid of the disease. "At that time, people didn't know the bactericidal mechanism of silver." Said A. Bart flick, a plastic surgeon and trauma recovery expert in Clayton, Georgia. Frick, who often uses silver for local trauma treatment, said: "it is clear that silver is only good for people's health, and there is no harm in terms of the situation at that time. So people see silver as a "safe metal."
Nowadays, silver is widely used, for example, it is used to prevent eye infection of newborn, treat burns, and produce ionizing rinse water.
