The air-dried exudate from the unripe seed capsule of the opium poppy, Papaver somniferum, or its variant, P. album. It contains a number of alkaloids, but only a few - MORPHINE; CODEINE; and PAPAVERINE - have clinical significance. Opium has been used as an analgesic, antitussive, antidiarrheal, and antispasmodic.

Syn. : o. crudum, meconium. The inspissated juice of the unripe capsules of Papaver somniferum and its varieties. Besides water, resin, fatty matter, gum, caoutchouc, pectin, glucose, and other substances not yet definitely determined, o. contains numerous alkaloids, of which morphin, codein, narcotin, and narcein are used in medicine. These bases occur in combination with meconic and lactic acids. Two neutral principles, meconin and meconoisin, have also been isolated. O. is a narcotic, acting directly upon the cerebrum. It destroys life by paralyzing the respiratory centers in the medulla. O. is chiefly used for the relief of pain, but its diversity of properties gives it a wide range of usefulness. An unconquerable longing for o. or one of its alkaloids often leads to its habitual use, which causes anemia, emaciation, headache, vertigo, wakefulness, tremor, and mental disturbance [U. S. Ph. Br. Ph.]. List of poisons and their antidotes, see in appendix [Gr.]
