In reality, Laudanum, also known as Tincture of Opium, 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 time in which the events in the Amnesia games occur, it was very common for people to use it for treating pain and wounds, so it seems very logical to include them as healing items.
A 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 laudanum bottle can also be found in Amnesia: Justine.

- In the room where you find the copper tube.

- There is a laudanum bottle found on the Level Editor on the Wine Cellar map that can only be seen in the editor, but not in game. In the room with the Calamine in it, there is another Laudanum in a chest. After you pick up the Calamine and are temporarily incapacitated, stack boxes to get up on the higher shelf that the barrel fell from. You should see the very chest with the Laudanum in there.
