As part of preparing for an examination, I'm reading a book called "Word Power Made Easy" by Norman Lewis. Here, the word "anaphrodisiac" is defined, but not without a piece of the author's mind.
Anaphrodisiac (Ən-af′-rƏ-DIZ′-ee-ak′)—both a noun and an adjective. Saltpeter is
supposedly an anaphrodisiac; so, some people say, is a cold shower, which is highly
doubtful. The best temporary anaphrodisiac is probably sexual intercourse.
In the context of Cupid's Poisoned Arrow. Makes total sense!
