Etymology: The word is a medical coinage built from parts that already existed. Its core is "irritant", which came into English from French "irritant", itself drawn from Latin "irrītō", meaning "to irritate" or "to provoke". The prefix "ab-" comes from Latin "ab", meaning "from" or "away". Joined together, the pieces describe something that works in the opposite direction to an irritant: where an irritant provokes inflammation or discomfort, this agent draws that irritation away and soothes it. The meaning rests on that reversal. Medicine often builds names by attaching a prefix to a familiar term, so a remedy that undoes the effect of an irritant could be named simply by reversing the direction of the word's action. The result is a precise technical label rather than a word with a long popular history, and it appears in medical dictionaries such as Taber's Encyclopedic Medical Dictionary.

Synonyms: soothing agent, calming agent
