The Arabian authorities treat, among the deleterious substances, of flesh and fish which have been cooked and hung up in a wet place until they have become unwholesome. When eaten in this state, Rhases says they bring on violent vomiting and purging, and may prove fatal unless the proper remedies are applied. For these symptoms he recommends repeated emetics and then purgatives; after which wine and pepper is to be given; and, in the end, the remedies for poisonous mushrooms. (Ad Mansor. viii, 27, 28.) See also Alsaharavius (Pract. xxx, 2, 15); Haly Abbas (Pract. iv.) Haly Abbas recommends vomiting by means of tepid water, oxymel, and salt. They treat, in like manner, of rancid fruits; which they state act as poisons when eaten in large quantity. For the cure of these they recommend emetics, the rob of bitter grapes, and medicines to whet the appetite. Rhases (ad Mansor. viii, 30); Avicenna (iv. 6; i, 30.) Avenzoar relates, at considerable length, the history of a case in which delirium and other bad symptoms had been brought on and kept up by drinking out of a cup which had been poisoned with some putrid meat. (i, 9, 9.) SECT. LVII.—ON HERACLEAN HONEY. Those who eat or drink the honey formed in Heraclea, of Pontus, experience the same symptoms as they who have drunk of wolfsbane, and the same remedies will be applicable. They are readily relieved by drinking frequently of mulse, having the leaves of rue mixed with it. * * * * * COMMENTARY. This section is taken from Dioscorides. Avicenna makes mention of a poisonous kind of honey produced in Arabia, for which he applies much the same remedies as those recommended by our author. (iv, 6; i, 32.) The effects of Pontic honey in occasioning madness is mentioned in the ‘Anabasis’ of Xenophon (iv, 8.) The same character of it is given by Aristotle, Pliny, Diodorus Siculus, and Ælian. Tournefort confirms the ancient accounts of its inebriating effects. See Sprengel (ad Dioscor. ii, 103.) SECT. LVIII.—ON GYPSUM. Gypsum, when drunk, produces suffocation, by being converted into stone; hence we must transfer the remedies applicable to those who have taken mushrooms, giving them in this case, and substituting the decoction of mallows for oil; for being of a fatty nature it lubricates the parts, and prevents them from being injured by the stony hardness of the gypsum. Oil, also, in honied water is proper; and the decoction of figs, and the lye of figs, or of the ashes of vine-shoots with much wine, and marjoram, or thyme with lye or vinegar. Clysters are also to be administered, consisting of must and the decoction of mallows. * * * * * COMMENTARY. Our author copies closely from Dioscorides.
