Pronunciation

Etymology

It is borrowed from German Heroin, a trademark registered in 1898 by Friedrich Bayer & Co. for their substitute for morphine.[2][3][4][5] By tradition the name comes from Ancient Greek ἥρως (hḗrōs, “hero”) (see hero) and the chemical suffix -ine, from the drug's effect on the user's self-esteem,[3][6][7] but Etymonline finds no evidence for this, and Barnhart and Hoad call the name unexplained or uncertain.[3][2][8]

Earliest recorded meaning

1898.[2][3][5][4] The Lancet of December 1898 reported trials of the new hypnotic in Professor Gerhardt's clinic in Berlin.[3]

Semantic evolution

Before the trademark was registered, a report on fifty patients with lung disease at a Berlin hospital found the drug effective against coughs, leaving patients comfortable and drowsy with no unpleasant side effects.[2]
