Laudanum (also known as Tincture of Opium) is an alcoholic herbal preparation containing approximately 10% powdered opium (the equivalent of 1% morphine). It is reddish-brown in color and extremely bitter to the taste. Laudanum contains almost all of the opium alkaloids, including morphine and codeine.
