In reality, Laudanum is an alcoholic herbal preparation containing approximately 10% powdered opium by weight (the equivalent of 1% morphine). A potent narcotic by virtue of its high morphine concentration, laudanum was historically used to treat a variety of ailments, but its principal use was as an analgesic and cough suppressant.
During the 19th century, in which the events in the Amnesia games occur, laudanum was commonly used when treating pain and wounds, making it a fitting healing item in the game.
One bottle of laudanum heals Daniel by 25% of his health or one health level:
- All is good
- A few cuts and bruises
- A wound is bleeding quite badly
- Barely conscious
There are a total of 16 Laudanum bottles that can be found throughout Amnesia: The Dark Descent. This is enough to heal Daniel from "Barely conscious" to "All is good" five times, and still have one bottle to spare. One (1) single bottle of laudanum can also be found in Amnesia: Justine.
