Even so; some gloomy souls affirming that it is proving with that great invention as with brandy or eau-de-vie, which, upon its first discovery, was believed by the doctors to be, as its French name implies, a panacea—a notion which experience, it may be thought, has not fully verified.
-- Herman Melville, The Confidence-Man: His Masquerade, 1857
Panacea derives from Greek panakeia, from panakes, "all-healing," from pan-, "all" + akos, "cure."
