COMMENTARY. It would appear that Hippocrates applied the term to all drastic purgatives. See Eustathius, Iliad. (xviii, 564.) By Dioscorides and all subsequent authorities, it is restricted to signify the fecula of the _Momordica Elaterium_, or wild cucumber. It was much used by the ancient physicians in the cure of dropsy, as we have stated in the Third Book. Dioscorides correctly states that it evacuates bile and phlegm, both upwards and downwards. He recommends it particularly in cases attended with difficulty of breathing. As an emetic, he directs us to administer it in oil, or with the ointment of iris. As a purgative, he recommends it to be given with double the quantity of salt and some mustard, in the form of a pill, of the size of a tare. Like our author, he states that it is emmenagogue, and proves fatal to the fœtus when applied in a pessary. Galen and the other authorities on the Materia Medica give it nearly the same characters. Theophrastus states that it is the most durable of all medicines, and that the oldest is the best. (H. P. ix, 14.) It is said by Hippocrates, that if a woman or she-goat, giving suck, partake of elaterium, it will affect her young. (Epid. vi, 5.) Galen in his commentary remarks, that other purgatives have the same effect when given similarly. (Op. t. v, 218, ed. Basil.) The Arabians also show a good practical acquaintance with this substance. Thus, for example, Avicenna praises it strongly in affections of the chest attended with difficulty of breathing, and more especially in cases of dropsy. He recommends it also in the form of a clyster for the cure of diseases of the joints and sciatica, and speaks of a plaster of it for the gout. He directs a pill to be prepared from it with double the quantity of salt. He states correctly that it occasions evacuations of phlegm and blood; that it is diuretic, and emmenagogue, and kills the child in a suppository. (ii, 2, 177.) Mesue also writes of the wild cucumber and elaterium with great precision, recommending the latter internally as an emetic, a phlegmagogue, and a hydragogue, more especially in dropsy. He also recommends it in jaundice, and _engorgement_ of the liver and spleen; and states that it is most beneficial in sciatica when administered in a clyster or applied as a plaster. He speaks highly of the efficacy of the roots of the wild cucumber when applied to the head, in a cataplasm for hemicrania, and as an errhine in the same complaint. (De Simpl. ix.) Serapion also, in treating of the wild cucumber, gives interesting extracts, both from Greek and Arabian authorities, respecting the medicinal powers of elaterium. (De Simpl. 204.) Ebn Baithar gives a most ample account of it. (ii, 276.) Ἐλάτη, Abies, _the Fir_; this tree is calefacient and desiccative, like the black poplar. Its resin will be treated of among the resins. * * * * *
