The National Institute of Health has proposed that cotton be eliminated because it contains moisture inside the bottle.
You've probably noticed that medicine bottles have a piece of cotton on top, so at least sometimes you've asked what it's for.
Drug manufacturers originally put cotton in bottles to immobilize the drugs so they wouldn't break during shipping, so cotton was used to fill the empty space in the bottle.
And that really makes sense.
In recent times, drugs are wrapped with some kind of film, so that damage can hardly happen and the use of cotton is pointless.
However, this tradition still continues, because this is a sign that the drugs are not poisonous.
It is clear that this proposal has not been approved in its entirety.
You can still see cotton in the bottle, but the question is whether it is cotton or some artificial material.
