COMMENTARY. It is the _Capparis spinosa_, namely, the plant which produces our officinal capers. Dioscorides and Serapion mention that pickled capers act as a gentle laxative, but say that they are bad for the stomach. The Arabians held that they are good whetters of the appetite. Casiri (Bibl. A. H. i, 337.) Galen gives a very elaborate article on the virtues of capers, which, he says, are the best medicine which we possess in scirrhous enlargement of the spleen. He says it clears away the humours by the belly and by urine, and also acts as an emmenagogue. Their taste, he says, is a combination of bitterness, acrimony, and sourness. He concludes by stating that capers produced in very warm climates, such as Arabia, are much more acrid than in his country. (De Simpl. vii.) The Arabians held that capers are aphrodisiacal and alexipharmic. See Rhases (Contin. l. ult. i, 164), Avicenna (ii, 2, 138), and Serapion (c. 291.) Κάρδαμος, Nasturtium, _Cress_; the seed of it is caustic like mustard. When applied externally, therefore, it proves rubefacient, incides also the thick humours when drunk with other things. And the dried herb is possessed of similar powers, but the juicy one is more moderate; it therefore is eaten raw. * * * * * COMMENTARY. It was indisputably a species of cress, probably the _Lepidium sativum_. We have treated of it as an article of food in Book I. Our author’s account of it is mostly derived from Galen. Symeon Seth, with most of the authorities, calls it aphrodisiacal. Macer says, on the contrary, that its powers are equal to those of rue for repressing venereal desires. Dioscorides calls it alexipharmic, and says of it, that in fumigations it drives away venomous reptiles. It occurs in the Flora Hippocratica. See Dierbach. The Arabians treat of it very elaborately. See Rhases (Cont. l. ult. i, 472), Avicenna (ii, 2, 502), and Serapion (c. 359.) They agree that it evacuates bile both upwards and downwards, that it is aphrodisiac and alexipharmic. The cress (_Nasturtium_), until very lately, was admitted into our Dispensatory. See Gerard, Parkinson, Culpeper, and Quincy. Καρδάμωμον, Cardamomum, _Cardamum_, is also acrid, but weaker than the Cardamus. It has also some bitterness, by which it destroys intestinal worms, and with vinegar clears away scabies. * * * * *
