All synonymsEtymology
Borrowed from Spanish bezoar and/or French bézoard, based on Arabic بَازَهْر (bāzahr), from Middle Persian pʾtzhl (pādzahr, “bezoar, antidote”), from a compound of words meaning “to protect” and “poison” (literally “killing thing”), thus a bezoar was “that which protects against poison”. In ancient times, bezoars from animals were ground up and ingested as remedies for various maladies and as antidotes to poisons.
