In Ayurveda, silver has been used in the form of Bhasma (calcined formulation), called Rajat Bhasma, for 5000 years.
Ayurvedic medicine uses silver in small amounts as a tonic and elixir. It was used to treat neurological disorders, respiratory tract disorders, muscular dystrophy, infertility, urinary tract disorders and diabetes.
It only seems logical to assume, there must be some merit in this metal.

Silver has also been used for water purification, treating wounds, injuries, reconstructive orthopaedic surgery, cardiac devices, catheters and surgical appliances.
In the early 1800s, doctors used silver sutures in surgical wounds very successfully and that was a time when western scientists rediscovered what was known for thousands of years that silver is a powerful germ fighter.
Silver began to lose favour with the advent of antibiotics in around the 1930s.
With the rise of antibiotic resistance, silver is making a comeback as an useful broad-spectrum antimicrobial alternative.
