Origin

  1. Ancient Greekἥρως“hero”
  2. GermanHeroin
  3. Englishheroin

Since the 1890s, by genericization from German Heroin, originally a trademark, from Ancient Greek ἥρως (hḗrōs, “hero”) and the suffix -in (“-ine”). Said to have been called thus to evoke quick and sweeping effect as a painkiller and cough suppressant (its original uses). Alternatively explained as a reference to the heroic school of medicine.
