Ῥοιὰι,
Mala Punica, Pomegranates; the prevailing quality of all the species of them is an astringent power, by which they act as refrigerants and desiccants. But the sweet have this property in a less degree than the others. The austere are more refrigerant, but are of a drier nature and stomachic. Those which are acid are cooling in a greater degree, but have also something incisive in their nature. The kernels are more astringent and desiccative than the juice, but still more so the outer membrane or rind called Malicorium. The flowers called Cytini have similar powers.
Commentary. It is evidently the Punica granatum L. Woodville says, “Hippocrati arbor audit σίδη unde cortex fructus σίδιον.” They frequently occur in the Hippocratic treatises. (De Diæta, ii, &c.) Cytini is generally put for the flowers of the cultivated pomegranate, and balaustia for those of the wild. The bark of the root called malicorium by Celsus was much used. Pliny, like the medical authorities, speaks of them all as being excellent astringents. He recommends them particularly in cæliac affections and hæmoptysis. (H. N. xxiii, 57.) The most interesting of the ancient authorities on this head is Dioscorides, who says of the sweet pomegranate that it engenders heat and flatulence in the stomach, and hence is unsuitable in fevers; and of the acid, that it relieves ardor of the stomach, and is more astringent and diuretic, being unsavoury and styptic; that the vinous has an intermediate nature; that the kernel of the acid pomegranate, when dried in the sun and sprinkled on food and boiled with it, restrains fluxes of the stomach and bowels; that when macerated in rain-water and drunk, it is beneficial in hæmoptysis, and in a hip-bath is suitable in dysentery and other fluxes; and that the expressed juice of the kernels, when boiled and mixed with honey, is suitable to ulcers in the mouth, on the pudendum and anus; for pterygia on the fingers, spreading ulcers, fungus, earache, and complaints in the nose, and more especially those of the acid pomegranate. (i, 141.) He also treats separately of the flowers and the bark, recommending the latter as an anthelminthic medicine. Galen and the other Greek authorities treat of the pomegranate in nearly the same words as Paulus. It would exceed our limits to give a notice of the various cases in which Celsus prescribes this medicine. Suffice it to say, that he calls it stomachic, cooling, and styptic, and recommends the flowers, the bark, and the root for these and various other purposes. For the Arabians see Avicenna (ii, 2, 109, 313); Serapion (De Simpl. 129); Rhases (Contin. l. ult. i, 443); Averrhoes (Collig. v, 42); Ebn Baithar (i, 499). One of Serapion’s authorities, Ruffus, recommends the acid pomegranate in cardiac disease, and another, Aben Mesue, in cholera and syncope, which attends it. All praise it as a stomachic, more especially in the loss of appetite attending pregnancy, and in vomiting. Rhases and Avicenna say that pomegranate wine relieves intoxication. Both the sweet and the acid are held to be diuretic, but especially the latter. The flesh of the sweet purges yellow bile and strengthens the stomach. They all represent the rind as being anthelminthic. On this use of it, see [Book IV, 58], and Pereira (Mat. Med. 1101). It has been a question, by the way, whether the malicorium or σίδιον of the Greeks, was the rind of the fruit or the bark of the root. We used to think it the former, but the examination of a passage in Avicenna (l. c.) has satisfied us that the latter was also sometimes included. In the modern Greek Pharmacopœia both the bark of the root and the rind of the fruit are described, the term σίδιον being restricted to the latter.
Ῥοῦς βυρσοδεψικὴ,
Rhus Coriaria, Sumach; the fruit and juice of it come principally to be used by physicians, being considerably astringent and desiccative of the third order, but detergent of the second.
Commentary. It is the Rhus Coriaria, or Elm-leaved Sumach. This also was much used as an astringent. Pliny briefly says of it, “vim habet astringendi refrigerandique.” The Arabian writers on husbandry mention that in times of famine bread was sometimes made from sumach. Dioscorides says of it that its leaves are astringent, being applicable in the same cases as acacia. He recommends it in dysentery when given by the mouth, in a lavement and hip-bath, as an injection in cases of purulent discharges from the ears, and for many other practical purposes. He concludes with mentioning that it bears a gum which is put into the holes of carious teeth to relieve pain. (i, 147.) Celsus notices it but once, and then as an application to aphthous ulcerations of the mouth. (vi, 11.) It is mentioned as an astringent medicine and condiment in the Hippocratic treatises. (De Mulieb. and de Liquid. usu.) Galen, and the other Greek authorities after him, merely state its general properties as a medicine. The Arabians treat of it under the name of sumach, which it still retains. See Avicenna (ii, 2, 635); Rhases (Cont. l. ult. i. 695); Serapion (De Simpl. 225); Ebn Baithar (ii, 46, 163.)
Ῥύπος,
The Sordes, from copper statues or vessels, in which a considerable quantity of oil has been kept, having also some verdigris, is discutient, moderately desiccative and emollient. It therefore discusses unconcocted phymata. But the sordes in the palestra (which some call paton), has been described under the head of sweat. The sordes in the ears is said to cure whitlows.
Commentary. Sprengel gives a long dissertation on the sordes palestræ. (Ad Dioscor. i, 36.) Suffice it to say in this place that it was collected from the bodies of the wrestlers in the palestra, and consisted of oil, sweat, dust, and any powder used for cleansing the skin. Sprengel, from a passage in the works of Theophrastus (H. P. v, 9), infers that the sordes gymnasiorum were collected from statues made of cedar, but he appears to have overlooked the account of it given by our author, from which it must be obvious that it was collected from statues of copper, or rather of bronze. The sordes balneorum, which is treated of by Dioscorides (i, 34), will be readily understood from the description which we have given in another place ([Vol. I, 68]), of the preparatory process which the bathers went through before going into the bath. It must have consisted then of human sweat and other impurities extracted from the skin, mixed up with soda, flour of beans, or any other substance used in cleansing the skin by means of the comb (strigil.) Dioscorides says it is heating, emollient, and discutient, and is used as a liniment to fissures and condylomata. These articles are treated of by most of the other authorities. On the sordes palestræ, see in particular Galen. (T. ii, 136, ed. Basil.) For the Arabians see Avicenna (ii, 2, 648), and Serapion (De Simpl. 169).
