Silver is used to make money, jewellery, photography, mirrors, batteries, silverware, and medical equipment. Because it is so bendable, it can be made into wires or shaped.
And silver has had medical uses for thousands of years too. Hippocrates, the father of modern medicine, wrote of the healing properties of silver. And silver does have a toxic effect on some bacteria, algae, fungi, and viruses. In fact, silver was used successfully in WWI to treat infections before the invention of antibiotics.
Silver has medicinal uses, even today. Today, wound dressings containing silver are well established for clinical wound care and have recently been introduced in consumer products such as sticking plasters.
Of course, silver has been used as money for thousands of years. Until 1964 many US coins were 90% silver, though today silver is only used in special commemerative or collector’s coins here.
Dentists use silver in fillings
