History

Until the beginning of the 19th century, raw opium was used in diverse preparations known as laudanum (see Thomas de Quincey 's Confessions of an English Opium-Eater, 1821) and paregoric elixirs, a number of which were popular in England since the beginning of the 18th century; the original preparation seems to have been elaborated in Leiden, the Netherlands around 1715 by a chemist Jakob Le Mort; in 1721 the London Pharmacopoeia mentions an Elixir Asthmaticum, replaced by the term Elixir Paregoricum ("pain soother") in 1746.
