Etymology

Borrowed from French anaphylaxie, coined by French physiologist and parapsychologist Charles Richet and by French zoologist Paul Portier from the Ancient Greek ᾰ̓νᾰ- (ănă-, “(intensifier) thoroughly”) from ᾰ̓νᾰ́ (ănắ, “to, again, upon”) and φύλαξις (phúlaxis, “protection, watching, guarding”).
