Laudanum for pain, blue vitriol for running sores! Laudanum or paregoric elixir was a syrup made with opium. A few drops in a glass of water sent one to heaven. As to vitriol, it's more commonly known as sulfuric acid.
Laudanum is an alcoholic tincture of opium, sometimes sweetened with sugar and also called wine of opium. The century was marked by the widespread use of laudanum as it was cheaper than a bottle of wine as it was not taxed as an alcoholic beverage.
