What does febrifuge mean?
A febrifuge is a medicine or other agent that reduces fever — in modern clinical language, an antipyretic. The word comes from the Latin febris, 'fever', combined with fugare, 'to drive away', so it literally means something that puts fever to flight. Before twentieth-century pharmacology, febrifuges such as willow bark and cinchona bark were among a physician's most valued remedies; the former yielded aspirin and the latter quinine, both of which remain important drugs today. Although 'febrifuge' still sees occasional use in pharmacology, it now sounds formal and slightly old-fashioned, appearing mostly in historical discussions of medicine or in botanical descriptions of traditional remedies. In ordinary conversation one would say 'fever medicine'. The related adjective form is febrifugal, describing anything having the property of reducing fever.
A medicine or agent that reduces or prevents fever.
"Cinchona bark served for centuries as the Western world's chief febrifuge against malaria."
Formal register; largely replaced in clinical usage by 'antipyretic'.
Having the property of reducing fever.
"The herbalist praised the plant's febrifuge properties."
This adjectival use is less common than the noun and is often replaced by 'febrifugal' or by phrases like 'fever-reducing'.
Standard regular plural; used when referring to multiple fever-reducing agents or remedies.
"Nineteenth-century apothecaries stocked dozens of plant-based febrifuges."
Before modern pharmacies, physicians reached for willow bark and cinchona as febrifuges — nature's own fever-fighters that eventually gave us aspirin and quinine.

Etymology of febrifuge
Febrifuge derives from the Latin febris, meaning fever, joined to fugare, 'to put to flight' or 'drive away', the same verb that gives us words like refuge, centrifuge, and subterfuge through its root fugere, 'to flee'. The word entered English in the early seventeenth century, when medical vocabulary drew heavily on Latin. Its cognates include febrile, from the same Latin febris, and the family of '-fuge' compounds formed with the fleeing root.
