Chapter XIV: Book I: , 68.) Of course it would consist of nothing but animal sweat, (10)

Pulmo, _Lungs_; those of lambs and swine are believed to cure the skin which has been chafed by shoes. But the lungs of a fox when dried are said to cure asthmatics. The Pulmo marinus, when fresh and pounded, cures gout and chilblains.

* * * * *

COMMENTARY. Dioscorides, Galen, and Serapion give nearly the same account of the medicinal properties of _lungs_. The _Pulmo marinus_ is the species of _Medusa_ which bears this scientific name. Our author and all the others follow Dioscorides in defining its medicinal properties. (ii, 39.)

Πολεμώνιον,

Polemonium, _Greek Valerian_ (called by some Philetærium), is attenuate and desiccative. Hence some give the root of it in wine for ischiatic disease, dysentery, and scirrhus of the spleen.

* * * * *

COMMENTARY. It is the _Polemonium cæruleum_, Greek Valerian. It occurs in the Hippocratic treatises (Hippiatr. 108, ed. Basil), but is not found in the works of Celsus. Dioscorides recommends it to be given for the bites of venomous reptiles, for dysentery, dysuria, sciatica, and diseases of the spleen, and also as a masticatory for toothache. He further mentions that it was used as an amulet for the sting of the scorpion. (iv, 8.) Our author copies from Galen, as does also Aëtius. We have not been able to trace it in the works of the Arabians, with the exception of Ebn Baithar, whose account of it is made up entirely of extracts from Dioscorides and Galen. (i, 186.) Though it disappeared from our Dispensatory long ago, its root is still to be found in the shops of our apothecaries, where it retains the character of being astringent, vulnerary, and anti-dysenteric. See Gray (Suppl. to Pharm. 55.)

Πόλιον,

Polium, _Poley_; the smaller, which we use for antidotes, belongs to the third order of calefacients and desiccants. It therefore removes obstructions of all the viscera, and proves diuretic and emmenagogue. While green it agglutinates large wounds, and when dried it cures ill-conditioned ulcers if sprinkled upon them.

* * * * *

COMMENTARY. The species indicated by our author is evidently the first species of Dioscorides, namely, the _Teucrium Polium_. The other is the _Teucrium Creticum_. Both these plants retained a place in our Dispensatory down to the days of Quincy (118), and both of them are still to be found in the shops of the apothecaries. Gray (Pharmacop. 49.) See further Parkinson (Theatre of Plants, 23), and Rutty (Mat. Med. 402.) Dioscorides says of both, that their decoction taken internally is beneficial to the bites of venomous reptiles, in cases of dropsy, jaundice, and diseases of the spleen along with vinegar; that it loosens the belly and is emmenagogue, but induces headache and is bad for the stomach; that in fumigations and placed below a couch, that they drive away reptiles; and in a cataplasm are vulnerary. Galen, Aëtius, and Oribasius, give them nearly the same characters. Celsus barely notices it once as one of the ingredients in the celebrated theriac of Mithridates. (v, 23.) The Arabians treat of the two species at greater length than the Greeks. See Avicenna (ii, 2, 537); Rhases (Cont. l. ult. i, 558); Serapion (c. 165); Averrhoes (Collig. v, 42.) They agree with the Greeks in considering it diuretic, emmenagogue, and a gentle purgative, and recommend it further as being anthelminthic and a remedy in cases of protracted fever. Serapion, by the way, quotes Dioscorides as calling the polium aphrodisiacal, but there is nothing in the chapter of Dioscorides on the poley to this effect.

Πολύγαλον,

Polygalon, _the Milkwort_, has leaves which are moderately austere. When taken in a draught it seems to engender milk, being of a hot and humid temperament.

* * * * *

COMMENTARY. That it is the _Polygala amara_ seems quite certain. Dioscorides and Galen treat of it in nearly the same language as our author. We have not been able to find it in the works of the Arabians except Ebn Baithar, who merely copies Dioscorides and Galen. (i, 186.)

Πολυγόνατον,

Polygonaton, _Solomon’s Seal_, is a mixture of astringency, acrimony, bitterness, and a certain indescribable nauseous principle, and therefore it is not much used. Some sprinkle the root of it upon wounds, and clear away spots on the face with it.

* * * * *

COMMENTARY. It has been usually taken for the _Convallaria Polygonatum_, which has obtained the same character as a medicine in modern works on the Mat. Med. See Rutty (M. M. 403) and Gray (Suppl. to the Pharmacop. 23.) Our author copies almost word for word from Galen, who, in his turn, borrows from Dioscorides. None of the Arabians have noticed it, as far as we can discover, except Ebn Baithar, who merely gives the descriptions of it by Dioscorides and Galen. It is not to be found in the works either of Hippocrates or Celsus.

Πολύγονον,

Polygonon, _Knot-grass_, has some astringency, but a cold watery principle of the second order is what prevails in it. When applied cold externally, it therefore relieves ardor of the stomach, erysipelas, and hot inflammations. Being of such a nature it repels defluxions, and thereby appears to be desiccative. The male is stronger than the female.

* * * * *

COMMENTARY. Of the two species described by Dioscorides, the mas is undoubtedly the _Polygonum aviculare_, and the feminine probably the _P. maritimum_. How the latter could be the _Hippuris vulgaris_, as several of the older commentators on Dioscorides had supposed, we are at a loss to comprehend. Two plants so dissimilar as the knot-grass and the mare’s-tail, could never have been classed by the ancients as male and female. Dioscorides gives a most interesting exposition of the medicinal powers of the former species, but as our author borrows from him, we need not dwell upon the other. It is possessed of an astringent and refrigerant power, and its juice (decoction) is suited to cases of hæmoptysis, fluxes of the belly, chorea, strangury, and so forth. (iv, 4, 5.) Galen taxes Dioscorides with not stating precisely what the particular cases of strangury are in which it is applicable. Otherwise his characters of this article agree exactly with those of Dioscorides and our author. Celsus ranks “herba sanguinalis, quam Græci πολύγονον vocant,” among things which are at the same time gently repressing (astringent?) and emollient. (ii, 33.) The Arabians who treat of the polygonum follow Dioscorides. See in particular, Avicenna (ii, 2, 725) and Ebn Baithar (ii, 195.) Our quaint old herbalist Culpeper, under the head of knot-grass, assigns to it exactly the same medicinal virtues as Dioscorides does to the Polygonum Mas and although the _Polygonum aviculare_ was ejected from our Dispensatory more than a hundred years ago, it is still to be found in the shops of our apothecaries, where it has the reputation of being “a vulnerary and astringent herb.” Gray (Suppl. to the Pharmacop. 42.)

Πολύκνημον,

Polycnemon, is heating and desiccative in the second degree, so as to agglutinate wounds.

* * * * *

COMMENTARY. It has been supposed to be the _Mentha arvensis_, but nothing is known of it for certain. Nicander notices it in two places. (Alex. 57, and Theriac. 359.) Dioscorides calls it a vulnerary herb, and a remedy for strangury and inward bruises. (iii, 98.) Galen gives the same account of it as our author. The Arabians do not appear to have treated of it.

Πολυπόδιον,

Polypodium, _Polypody_, is possessed of considerably desiccative powers without pungency. When drunk it purges downwards.

* * * * *

COMMENTARY. Dioscorides says of the root of the π. (_Polypodium vulgare_), that it is purgative, and is given to evacuate phlegm and bile; that it makes a good application to sprains and fissures in the hands. (iv, 185.) Galen and the other Greek authorities merely state its properties in general terms, like our author, with the exception of Ruffus, who treats of it more elaborately. He says it evacuates phlegm, bile, and water; that it should be taken in mulse or water before a meal, when it will purge gently, and thus prove an excellent laxative, especially to children; but that in disease it is not a purgative possessed of much efficacy. (Opera, 14.) The Arabians, and especially Mesue, seem to have attached more importance to it. See Mesue (De Simpl. 5); Serapion (c. 248); Avicenna (ii, 2, 535); Averrhoes (Collig. v, 42); Ebn Baithar (i, 227.) Mesue recommends it in joint diseases, colic, hardness of the spleen, fevers connected with black bile, and fissures of the hands. The polypody retained its place in the Dispensatory with its ancient characters as late as the time of Quincy (137), and even in the age of Lewis it had not been wholly rejected. (ii, 244.) There seems no good ground for questioning its efficacy as a gentle laxative. See Gray (Suppl. to Pharmacop. 13.)

Πομφόλυξ,

Pompholyx, is desiccative without pungency, so that it is useful for carcinomatous and other ill-conditioned ulcers. It is also an ingredient in ophthalmic remedies.

* * * * *

COMMENTARY. What this substance was is well stated by a comparatively recent writer on the Materia Medica. Dr. Lewis, treating of zinc, says, “Moderately pure white flowers sublimed from it in the brass or other furnaces, wherein zinc, or its ores are melted with other metals, were formerly kept in the shops and distinguished by the names of pompholix and nihil album.” (Mat. Med. ii, 485.) A still later authority on the Pharmacopœia describes it thus: “_Pompholix Nihil album._ Collected in the smelting furnaces wherein zinc ores or brass are melted; used in ointments for tutty.” Gray (Suppl. &c. 234.) It is also distinctly described by Geoffroy (Treatise on Fossil, &c. Subst. 185), and by Quincy (201.) The latter writes as if he had been familiar with this article; but it appears singular that the former says that in his time (that is to say, about 150 years ago) it was unknown in the shops. For the ancient authorities on it, see in particular Pliny (H. N. xxiv, 33), and Dioscorides (v, 85.) The latter calls it styptic, cooling, and to a certain extent escharotic. Galen recommends it in carcinomatous and all ill-conditioned ulcers, for those about the parts of generation and anus, and for ocular collyria. (De Simpl. ix.) The Arabians treat of it under the head of Tutia. See in particular Serapion (c. 422); Avicenna (ii, 2, 695); Averrhoes (Collig. v, 43); Ebn Baithar (i, 217.) Hardly one of them does anything more than copy the description of it given by Dioscorides and Galen, only comprehending under one name what the Greeks had delivered regarding pompholyx and spodium separately.

Πορφύραι,

Purpuræ, when burnt are possessed of the same powers as shells. The part which serves as a cover to them when boiled in oil, strengthens hairs that are falling out. When drunk with vinegar, they cure swelling of the spleen. As a fumigation, they rouse in cases of uterine suffocation, and expel the secundines.

* * * * *

COMMENTARY. The shell-fishes which supply the purple dye. It is got from various fishes, but more especially the _Helix ianthina_, _Murex brandaris_ and _trunculus_. For an account of them, see particularly Aristot. (Hist. Animal. v, 14), and Pliny (H. N. ix, 60.) Our author borrows from Dioscorides (iii, 4), and Galen (De Simpl. xi.) We have not been able to detect this article in the works of the Arabian authorities.

Ποταμογείτων,

Potamogiton, _Pondweed_, is cooling and astringent, like Polygonum, being possessed of similar powers to it.

* * * * *

COMMENTARY. It is the _Potamogiton natans_, L. Dioscorides says of it, that it is cooling and astringent, and is applicable in cases of pruritus, and in spreading and inveterate ulcers. (iv, 99.) In some of the editions of his works, another species is described and recommended in dysentery, colic, and the red fluor of females. It cannot be so decidedly determined. Galen and the other authorities treat of it in general terms, like our author. Such of the Arabians as treat of it borrow from Dioscorides. See Avicenna (ii, 2, 352.)

Ποτέρριον,

Poterrhium, (called by some Phrœnium); its roots when cut into slices agglutinate divided tendons and wounds; and the decoction of it when drunk relieves affections of the nerves.

* * * * *

COMMENTARY. Matthiolus confesses his ignorance of it. Sprengel is inclined to think that it is the _Astragalus Poterium_, Pall. But Dr. Lindley holds it to be _Astragalus Creticus_. (Veg. King. 548.) Dioscorides says it has stalks like those of tragacanth, and accordingly Linnæus holds this plant to be a species of tragacanth. He recommends it in exactly the same cases as our author. Galen describes it by the name of _Neuras_. We have not been able to detect it in the works of the Arabians.

Πράσιον,

Marrabium, _Horehound_, is calefacient in the second degree; but more desiccative. It removes obstructions about the liver and spleen, and those of the chest and lungs. It also promotes menstruation. In a cataplasm it is detergent and discutient, and otherwise it is detergent and incisive.

* * * * *

COMMENTARY. The _Marrubium vulgare_. Dioscorides has an elaborate section on the virtues of this article, which he recommends particularly in phthisical, asthmatic, and catarrhal complaints, as being an excellent expectorant, for promoting the menstrual and lochial discharges, as an alexipharmic, &c. He adds, however, that it is unsuitable in affections of the kidneys and bladder. (iii, 109.) Galen writes thus of it: “Horehound, as it is bitter in taste, so, by general admission, it has the virtue corresponding to that taste, being a deobstruent of the liver and spleen, clearing away matters about the chest and lungs, and promoting menstruation.” He also mentions its use in a cataplasm and in other cases, as stated by Dioscorides. Aëtius and Oribasius state its virtues in nearly the same terms. It is the “Marrubium” of Celsus, who prescribes the juice of it in phthisis (iii, 22), in paralysis (iii, 27), in ulcers of the throat (iv, 4), and for other purposes. For the Arabians, see in particular Serapion (c. 198); Avicenna (ii, 2, 553); Averrhoes (Collig. v, 42.) Avicenna recommends it as deobstruent, emmenagogue, and an application to the eyes. Serapion also praises it as a deobstruent, and recommends it particularly in ulcers of the lungs, asthma, and such like complaints. It would seem to deserve the characters which the ancient authorities give it from Hippocrates down to Macer Floridus and Serapion. See Rutty (Mat. Med. 309.) Even yet it holds a place in the Dispensatory.

Πράσον,

Porrum, _Leek_, consists of unwholesome juice and is acrid; but Dioscorides says, that it induces disagreeable dreams, agrees well with the bowels, is diuretic and attenuant. It is also detergent, for it proves expectorant when boiled in ptisan. The seed of it is mixed with nephritic remedies. But the leaves have some astringency, and therefore the juice of it proves styptic.

* * * * *

COMMENTARY. Without doubt it is the _Allium Porrum_, L. Diphilus, as quoted by Athenæus says, “it is attenuant, nutritious, and flatulent.” (Deipnos, ix, 3.) Dioscorides recommends it in the cases enumerated by our author, and also in several others. (ii, 178.) Galen does not treat of it at all in his work on Simples. The Arabians attach more importance to it, recommending it as being emmenagogue, diuretic, aphrodisiac, and so forth. They say of it that it hurts the eyes, the gums, and the teeth. See in particular Avicenna (ii, 2, 540); Rhases (Cont. l. ult. i, 562); Serapion (c. 361); Averrhoes (Collig. v, 42); Ebn Baithar (ii, 339.)

Πρίνος,

Ilex, _the Holm Oak_, has powers resembling those of the oak, but it is much stronger.

* * * * *

COMMENTARY. It is the _Quercus Ilex_, or _Evergreen Oak_. All the authorities speak of it as being a powerful astringent. The _Kermes_, or Scarlet Grain is produced upon the ilex by a certain class of insects. It is described by Theophrastus and Pliny, as stated under that head.

Πρόπολις,

Propolis, _Virgin-wax_, or _Bee-glue_, is calefacient in the second degree and moderately detergent. It is also possessed of attenuant and deobstruent powers.

* * * * *

COMMENTARY. Scribonius Largus calls it, “Propolis quam quidam sacram ceram vocant.” Dioscorides and Galen give nearly the same account of _Bee-glue_ as our author. It is the glutinous substance with which the working bees block up the holes in their hive. They gather it from poplars and other resinous plants. It occurs frequently in the works of the ancient writers on Pharmacy.

Πταρμικὴ,

Ptarmica, _Sneezewort_; the leaves are sternutatory; but the whole part, when green, removes hypopion and other kinds of ecchymosis, for it is hot and desiccative. The green belong to the second order, and the dried to the third.

* * * * *

COMMENTARY. Dioscorides’s description of it agrees well with the _Achillea Ptarmica_, except that (as is remarked by Sprengel) its favorite locality is meadows, and not mountainous and rocky situations as indicated by Dioscorides. All the Greek authorities, from Dioscorides downwards, give it exactly the same characters as our author. We have not been able to discover any traces of it in the works of the Arabians. Its leaves are still kept in the shops of apothecaries, and are held to be sternutatory. Gray (Suppl. to Pharm. 80.)

Πτελάια,

Ulmus, _the Elm_, is possessed of desiccative and detergent powers, so as to agglutinate wounds; but the bark of it still more, if, when in a fresh state, it be wrapped like a bandage about the wounds. It also cures leprosy with vinegar, and the roots of it are possessed of the same powers, so that fractures which will not unite are to be bathed with the decoction of it.

* * * * *

COMMENTARY. Most probably the _Ulmus campestris_. Our author’s statement of its medicinal virtues is closely copied from Dioscorides (i, 112.) Galen and most of the authorities represent it to be an agglutinative medicine. Pliny, like the others, recommends it as an application to leprosy. No mention of it occurs in the works of Celsus. The Arabians treat of it fully, but in the main follow Dioscorides. See Avicenna (ii, 2, 71, 96, 212); Rhases (Cont. l. ult. i, 250.) They recommend it in all cases requiring astringents and abstergents.

Πτερὶς,

Filix, _Fern_, is desiccative in its powers, and bitter. Hence it destroys the fœtus, and kills the broad intestinal worm when taken to the amount of four drachms in honeyed water. Because it is moderately astringent, it dries up ulcers without pungency.

* * * * *

COMMENTARY. Apuleius says, “Græci pterin, Latini filicem nominant.” (De Herbis.) We need not hesitate to refer it to the _Aspidium Filix Mas_, which has been long celebrated as a vermifuge medicine. See Book IV, 67, of this work, and Rutty (Mat. Med. 201.) Dioscorides recommends it merely as an anthelminthic medicine, and as one which is calculated to promote convalescence in diseases of the spleen. For the former purpose he directs it to be given with scammony or white hellebore, along with a diet consisting principally of garlic. (iv, 183.) Galen acutely remarks, that there is no wonder that it should be anthelminthic, seeing it is possessed of a bitter taste with some astringency. None of the other Greek or Arabian authorities supply any additional information respecting it. See in particular Avicenna (ii, 2, 620); Serapion (De Simpl. 56.) The “filicula” of Celsus (ii, 12) would appear to us to have been rather the Polypodium than the Filix Mas. In the modern Greek Pharmacopœia it is marked as being the _Aspidium Filix Mas_.

Πυκνόκομον,

Pycnocomon, is possessed of discutient, attractive, and acrid powers. The leaves of it, therefore, discuss phyma and furunculus. The fruit, in addition to these properties, also extracts sharp-pointed weapons. Its root purges yellow bile.

* * * * *

COMMENTARY. Although Dioscorides has given a pretty minute description of it, there are few articles in the ancient Mat. Med. about which there is so much uncertainty. See the Index Latinus to Parkinson’s ‘Theatre of Plants,’ and Sprengel (in Dioscor. iv, 173.) The latter decides that it is neither the _Leonurus Marrubiastrum_ nor the _Succisa pratensis_ as had been supposed. Whether it may be the _Cephalaria Pycnocomon_ we are unable to determine, as we have no acquaintance with this plant. Our author borrows his medicinal characters of it from Dioscorides (l. c.) Galen does the same. The Arabians have not noticed it, as far as we can discover.

Πύρεθρον,

Pyrethrum, _Pellitory_; the root has caustic powers, and allays the pain of teeth affected with cold; and before the occurrence of periodical rigors it is rubbed in with oil, and relieves those who are affected with torpor and paralysis.

* * * * *

COMMENTARY. It seems to be the _Anthemis Pyrethrum_, although Sprengel is not quite satisfied. It was much used in stimulant embrocations. Dioscorides, Galen, Macer, and Serapion, and, in a word, all the authorities, recommend it strongly as a phlegmagogue for toothache. Dioscorides says further of it, that when rubbed in with oil, it is sudorific, being serviceable in chronic rigors, for parts which have lost their natural heat and are paralysed. (iii, 37.) Celsus also mentions it in a list of stimulants, to be applied externally for toothache (vi, 9), and ranks it among his caustics. (v, 8.) The Arabians treat of it at considerable length, but borrow much from Dioscorides. See in particular Avicenna (ii, 2, 547); Rhases (Cont. l. ult. i, 553); Averrhoes (Collig. v, 42.) They all in particular recommend it as a sialogogue in cases of toothache. We need scarcely remark that the pellitory (now called _Anacyclos Pyrethrum_) still holds its place in the Dispensatory as a sialogogue and masticatory. We see no good reason, therefore, for questioning its identity with the pyrethrum of the ancients, more especially as it still retains a place in the modern Greek Pharmacopœia.

Πυρὸς,

Triticum, _Wheat_, is heating in the first degree, but is intermediate between dry and humid substances. It is also somewhat glutinous and emplastic.

* * * * *

COMMENTARY. Without doubt it is the _Triticum æstivum_. We have treated largely of it among the dietetical articles in the First Book, and have also treated of the farina, leaven, and pollen of wheat separately. We need not, then, enlarge further upon this article at present.

Πιτύα,

Coagulum, _Rennet_; all sorts of it are possessed of acrid, attenuating, discutient, and decidedly desiccant powers. But that of hares is represented as curing epilepsy if drunk with vinegar, and as curing the female discharge, and proving a solvent of coagulated milk in the bowels, and of blood in like manner. Some say that it restrains spitting of blood from the chest. The rennet of a horse is described as proving serviceable in cæliac and dysenteric affections. That of the seal is said to have the properties of castor.

* * * * *

COMMENTARY. Our author’s account of the medicinal properties of _Rennet_ is taken from Dioscorides and Galen. Indeed he has copied from the latter almost word for word. The Arabians treat of the rennets very fully and with much judgment. See in particular Rhases (Cont. l. ult. i, 221); Avicenna (ii, 2, 115); Serapion (De Simpl. 444); Ebn Baithar (ii, 604.) They follow Dioscorides very closely, among other things recommending rennet to be applied on a pessary for promoting the menstrual discharge, and for the hysterical convulsion. All rennets, they say, are alexipharmic, and especially those of the kid, of the antelope, and of the camel. As stated by us in the Fifth Book, the ancients administered rennet in cases of poisoning with curdled milk. It appears remarkable that an article unquestionably capable of being applied to so many medicinal purposes as rennet, should have been entirely excluded from our modern Dispensatories.

Ῥακὸς,

Panniculus, _Rags_; when those from wool are burnt they have similar powers to burnt wool. Linen, when burning, sends forth a subtile smoke, so as to prove deobstruent in catarrhs, and agree with risings of the womb. When burnt, its powers are nearly the same as those of wool.

* * * * *

COMMENTARY. These things are so well known as not to require further illustration.

Ῥάμνος,

Rhamnus, _Buckthorn_, is desiccative in the second degree, but cooling in the first. Hence it cures herpes and erysipelas when not very hot. Its tender leaves are to be used.

* * * * *

COMMENTARY. This appears to be the first species of Dioscorides, which we may decide to be the _Lycium Europæum_. The second is the _Lycium Afrum_. The third is not well ascertained, but probably is a species of _paliurus_. See Parkinson (Theatre of Plants, 1006), and Sprengel (Ad Dioscor. i, 119.) Dioscorides recommends the leaves of all the three kinds for herpes and erysipelas, and also mentions that the twigs of them were placed in doors and windows to avert sorcery. (i, 119.) Galen and the other Greek authorities treat of this article in nearly the same terms as our author. Pliny recommends it as a cooling and refrigerant application. (H. N. xxiv, 76.) The Arabians borrow their account of it entirely from Dioscorides and Galen. See in particular Serapion (De Simpl. 236); Rhases (Cont. l. ult. i, 591); Avicenna (ii, 2, 345); Ebn Baithar (ii, 223.)

Ῥάφανος,

Rhaphanus, _Radish_, is heating in the third degree, and desiccative in the second. The wild is more powerful. The seeds of both are stronger, and therefore they discuss hypopion and other lividities.

* * * * *

COMMENTARY. Dioscorides, like our author, describes two species, of which the former is certainly the _Rhaphanus sativus_, and the other probably the _R. maritimus_. Dioscorides gives so long a catalogue of the medicinal properties of the former or common radish, that we can scarcely venture upon an exposition of it. He says of it, that its seed is emetic, diuretic, and a cleanser of the spleen, when drunk with vinegar; that it is beneficial in cynanche, and alexipharmic both when taken internally and applied externally. Florentinus (Geopon. xii, 22) and Pliny (H. N. xx, 13) praise the radish as an antidote to poisonous substances and venomous animals. It was much used by the ancients as an emetic, and for this purpose it was taken before a meal as described by Celsus. (i, 3.) See also Dioscorides (l. c.) and Pliny (l. c.) Hence it is frequently prescribed by Nicander, as a remedy in the case of poisoning, as in that by henbane, and in that by mushrooms. It is also recommended in these and similar cases by Scribonius Largus (Compos. 198.) The radish we are confident is the “radicula” of Celsus, who prescribes it for various purposes, as being laxative, diuretic, and, as we formerly stated, emetic. (See Vol. II, 31, &c.) The Arabians attach much importance to this article, but do not supply much information regarding it but what they acknowledge to be derived from the Greeks. See Serapion (c. 307); Avicenna (ii, 2, 574); Rhases (Cont. l. ult. i, 571); Averrhoes (Collig. v, 42); Ebn Baithar (ii, 246.) They agree in stating of it, that taken before other food it renders vomiting easy; and after food that it loosens the bowels. All recommend it in cases of poisoning. They also prescribe it as a deobstruent in obstructions of the liver and in jaundice. The radishes, the garden and the wild, retain their ancient characters in the works of our old herbalists, and even in the time of Quincy they still held a place in our Dispensatory, although, as he says, “little used in medicine.” (i, 5, 409.)

Ῥῆον,

Rheum (called by some Rhâ), is composed of a terrene, cold, and subtile substance, and of a vaporous, hot, and slightly acrid one. Hence it relieves sprains and ruptures, and orthopnœa, and also lividities, by its discutient powers; and by its astringency, spitting of blood, cæliac and dysenteric affections. By both it cures hepatic complaints.

* * * * *

COMMENTARY. Our author manifestly copies from Galen; and whoever will carefully compare his account of it with Dioscorides’s chapter on Rhâ, cannot fail to come to the conclusion that both apply to the same substance, namely, the _Rheum Rhaponticum_. We therefore shall confine our attention in this place to it, reserving to the Appendix what we have got to say on the knowledge possessed by the ancients of the purgative rhubarb. Dioscorides says of it, that its prevailing power is astringency, with a certain degree of heat; and he recommends it to be taken in a draught for flatulence of the stomach, atony, all kinds of pain, spasms, diseases of the spleen, liver, and kidneys, tormina, affections of the chest and bladder, distension of the hypochondria, diseases of the uterus, sciatica, hæmoptysis, asthma, hiccough, dysentery, cæliac affections, intermittents, and the bites of venomous animals; also for lividity and leprosy when rubbed in with vinegar, and for discussing all chronic inflammations in a fomentation. (iii, 2.) Galen’s account of it, as already stated, is exactly the same as our author’s. Oribasius evidently takes his description of it from Dioscorides; and Aëtius, like our author, as clearly abridges Galen. There is no mention of the _Rhâ_ in the works either of Hippocrates or of Celsus. Pliny’s description of it (he calls it _Rhacoma_) is manifestly imitated from Dioscorides. (H. N. xxvii, 105.) As already stated, we shall reserve our exposition of the views of the Arabians to the Appendix.

Ῥητίναι,

Resinæ, _Resins_, are all calefacient and desiccative; but the turpentine holds the first place, being discutient, emollient, and attenuating, and also detergent, whereby it cures itch; and that of larch is like to it. The resin of the pitch-tree, and still more that of the wild pine, are more acrid, but neither more discutient nor attractive. Those of the pine and fir hold an intermediate place.

COMMENTARY. On the formation of _Resins_ see in particular Theophrastus (H. P. ix, 2) and Pliny (H. N. xxiv, 22.) Pliny thus sums up his account of them: “Summæ species duæ; sicca et liquida. Sicca e pinu et picca; liquida e terebintho, larice, lentisco, cupresso.” The Resina sicca pini is the _Pix arida_ of the Old London Pharmacopœia, or the _Pix Abietina_ of the New. The Resina liquida laricis is now generally called by the name of _Venice Turpentine_. The Resina lentisci is well known by the name of _Mastich_. The _Colophonian rosin_, which is often mentioned in this work, is the same as the black fiddler’s rosin. The Cypress rosin does not appear to be much known now. Pliny correctly observes that all these resins act on the bowels and the urine. The mode of burning or roasting resin is described by Dioscorides. (i, 93.) He gives a very interesting account of the _resinæ_ in general, which he represents to be emollient, calefacient, dissolvent, cleansing, suited for coughs and consumptions, in electuaries by themselves or with honey, clearing away matters from the chest; and as being diuretic, digestive, laxative of the bowels; adapted for the operation on trichiasis (see Book VI, 8), and for leprosy, with verdigris, copperas, and natron; for purulent ears with honey and oil, and for itching of the pudendum. They are mixed, he adds, with plasters, liniments, and acopa, and relieve pleuritic pains either when rubbed in or applied by themselves. (i, 91.) All the other authorities prescribe the resins freely, but none give so full a description of them as Dioscorides. See, however, Celsus (pluries), who appears to have been particularly fond of them. He recommends turpentine rosin with butter and honey in phthisis (iii, 22), in dyspnœa (iv, 4, 2), and in various other cases. Our author’s account of them would seem to be principally taken from Galen. The Arabians, as usual, copy from the Greeks, and supply little additional of their own. See Avicenna (ii, 2, 242); Serapion (De Simpl. 325); Averrhoes (Collig. v, 42); Rhases (Cont. l. ult. i, 580, &c.); Ebn Baithar (pluries.) All the resinæ here described occur in the modern Greek Pharmacopœia (160, 161.)

Ῥόδα,

Rosæ, _Roses_, are naturally composed of a watery substance, which is heating, astringent, and bitter. The flowers are still more astringent, and hence are desiccative.

COMMENTARY. It comprehended the _R. lutea_, Derlech, _R. arvensis_, and probably other species of the _Rosa_, L. Dioscorides gives a careful exposition of the particular uses of Roses in medicine. He says they are cooling and astringent. In preparing the flowers for use, he directs the nails or white portions to be clipped off with a pair of scissors, and the remainder compressed and pounded in a shade in a mortar, until they form into a ball. He recommends them in diseases of the eyes, headache, affections of the ears, gums, anus, and womb, &c., also when sprinkled in powder on intertrigo, and as an ingredient in the ointments called _calliblephara_. (i, 130.) We need not devote time to the exposition of what the other authorities have written on this subject. See Celsus (pluries); Galen (De Simpl. viii, et alibi); Avicenna (ii, 2, 568); Rhases (Cont. l. ult. i, 585); Serapion (De Simpl. 108). The Arabians say of rose-water that it is stomachic and hepatic; and of rose-oil, that it relieves inflammation of the stomach and loss of its tone. They recommend rose-water further both in syncope and in hæmoptysis. Like the Greeks, they make it an ingredient in their collyria to the eyes and eyelids. Rhases and Avicenna give particular directions for preparing an ablution with roses to remove fetid perspiration.

Ῥοδία ῥίζα,

Rosea radix, is heating in the second degree, and is attenuating and discutient.

* * * * *

COMMENTARY. The older commentators and herbalists are by no means satisfied that it was the _Rhodiola Rosea_, or rosewood; but the later authorities are pretty much agreed upon this point. See Sprengel (in Dioscor. iv, 45) and Lindley (Veg. Kingd. 631). Dioscorides merely recommends it along with valerian as an application to the forehead and temple in cephalalgia. The other authorities, like Paulus, are content with barely stating its general characters.

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
