pains, whether taken internally or rubbed in. It is useful, he says, in apostemes, especially in those of an inflammatory nature. He says of it, that it dries up ulcers; with the yelk of an egg forms a liniment for gout; it proves soporific if a cloth smeared with it be placed below the head; allays pain if injected into the ear affected, along with myrrh and saffron; allays chronic pains of the head, and sometimes cures them; soothes the pains of ophthalmy, and the apostemes of the eyes, with the milk of a woman; but yet he adds, that many of the ancient authorities had condemned the use of it in such cases as proving injurious to the sight; it allays incessant coughs, and often cures that kind which is noisy; improves the stomach in peculiar cases, when debilitated by excess of heat and humidity, is braced by it; but in many constitutions, opium, so administered, impairs digestion; it stops diarrhœa; is useful in dysentery, and in ulcerations of the intestines. It proves fatal, he says, by congealing the vital powers and extinguishing the innate heat; and its antidote is castor. He concludes by saying, that three times the amount of the seed of hyoscyamus, or double of the seed of mandragora, may be given as a substitute for it. (ii, 2, 519.) Haly Abbas treats of opium more briefly, stating in general terms that it is a soporific and sedative medicine. He seems to say that from half a drachm to a drachm will prove fatal. (Pract. ii, 40, 318.) Serapion’s account of opium is mostly made up of extracts from Dioscorides and Galen, with a few brief notices of the opinions held by Arabian authorities, which do not contain anything of much interest. (c. 374.) Rhases’s chapter upon the poppy contains many extracts from the Greek authorities on opium, with a few from Arabian writers, which, however, contain nothing of much interest after what we have given from Dioscorides and Avicenna. Like Serapion, he says, from half a scruple to a scruple is a dose, and that two drachms will prove fatal. His authority, Mesue, says it forms semen. Another of them, Joannitius, seems to say that it binds the bowels in general, but yet has some laxative power. (Cont. l. ult. i, 533.) In the ‘Book of Experience,’ as quoted by Ebn Baithar, poppy-juice is recommended in complaints of the eyes, and in pains of the head when applied to the forehead. One of his Arabian authorities mentions its good effects in diarrhœa; and it is also spoken favorably of as an application to burns. Ebn Baithar’s account of this article is otherwise mostly made up from Dioscorides. Ὀπὸς, Succus Cyrenaicus, Medicus, and Syriacus, are so named _per excellentiam_, being considerably hot and flatulent. The Cyrenaic is hotter and more attenuate than any of the others. * * * * *
