What's the difference between antibiotic, antiseptic and anti-bacteria?
gpt
'Antibiotic' refers to a class of drugs designed to kill and inhibit the growth of bacteria and/or other microorganisms within the body.

'Antiseptic' refers to any substance which is administered topically on *living* tissue to do same. Its mechanism of action is generally limited to the area upon which you apply it. Think hand sanitizer or iodine.

'Anti-bacteria' is anything designed to kill bacteria.
