the.com/relaxant

A drug that tells your muscles the emergency is over, even when it isn't.

means A substance, usually a medication, that eases tension in muscles (or sometimes the mind) by reducing their contraction or excitability.

from Built straight from the Latin verb relaxare — 're-' (back) plus 'laxare' (to loosen, from laxus, 'loose' or 'slack'). The same root gives English 'relax' and 'lax.' The '-ant' ending, from Latin's present participle form, turns the verb into 'the thing that does it' — so a relaxant is simply, etymologically, 'that which loosens.' The word's medical sense is a modern application of a very old idea about slackening what's drawn tight.
