Hint: Silver is used in medicines as it has antimicrobial and antibiotic effects. This is because silver has low toxicity and minimum risk when used at wound or bacterial infection.

Complete step-by-step solution:
Argyrols is also known as mild silver protein that acts as a strong antimicrobial to kill the bacteria without harming body tissues. It is used as an antiseptic for eye inflammation and Gonorrhoea infections.
