narcotic consisting of an alcohol solution of opium or any preparation in which opium is the main ingredient
A tincture of opium, once widely used for various medical purposes and as a recreational drug.
To add laudanum to (a drink or the like).
The word laudanum comes from New Latin lādanum, which originally meant a gum resin. Its meaning later shifted to refer to an opium preparation, likely influenced by the Latin verb for "to praise."
