The story of the word

John Jacob Abel coined epinephrine in 1898 from Greek for on-the-kidney, exactly what adrenaline says in Latin. Jokichi Takamine isolated the pure hormone and trademarked Adrenalin, which is why American pharmacology says epinephrine while British usage says adrenaline: a trademark dispute fossilised into two national vocabularies. Both words name the same molecule and the same gland.
