What does febrifugal mean?
Febrifugal is a formal adjective meaning capable of reducing, alleviating, or curing a fever. A physician might describe a medicine as having febrifugal properties, while a historical account could call a plant febrifugal because it was believed to relieve fever. The word is related to the now more familiar noun “febrifuge,” a substance or medicine used to treat fever, and it overlaps in meaning with the modern medical adjective “antipyretic.” Febrifugal is uncommon in contemporary English and is more likely to occur in technical discussion, older medical writing, or formal descriptive prose. Its unusual name gives it a distinctive history: it was formed from Latin elements associated with “fever” and “flee,” presenting the medicine as something that drives or puts fever to flight. Although largely superseded in ordinary usage, the word remains a precise example of specialized vocabulary formed through transparent Latin compounding.

A rare noun use, chiefly surviving in older or deliberately formal medical writing.
The plural is used only in the rare noun sense and is chiefly encountered in formal or historical contexts.
"Several febrifugals were prepared before the expedition departed."
Its name is a tiny Latin escape plan: febris, “fever,” combined with fugere, “to flee”—literally, “fever-flight.”

Where does febrifugal come from?
The word comes from the Latin adjective febrifugus, formed from febris, “fever,” and fugere, “to flee.” Its literal sense is therefore “fever-driving” or “fever-putting to flight.” The English adjective developed during the early modern period, when learned Latin compounds were commonly introduced into medical vocabulary.
