Chapter 7

The virtues of this plant seem to be little known in the present practice. We have frequently experienced excellent effects from a light infusion of carduus in loss of appetite, where the stomach was injured by irregularities. A stronger infusion made in cold or warm water, if drunk freely, and the patient kept warm, occasions a plentiful sweat, and promotes all the secretions in general.

The seeds of this plant are also considerably bitter, and have been sometimes used for the same purposes as the leaves.

189. CHIRONIA Centaurium. LESSER CENTAURY. The Tops. L. E. D.--This is justly esteemed to be the most efficacious bitter of all the medicinal plants indigenous to this country. It has been recommended as a substitute for Gentian, and, by several, thought to be a more useful medicine: experiments have also shown it to possess an equal degree of antiseptic power.

Many authors have observed, that, along with the tonic and stomachic qualities of a bitter, Centaury frequently proves cathartic; but it is possible that this seldom happens, unless it be taken in very large doses. The use of this, as well as of the other bitters, was formerly common in febrile disorders previous to the knowledge of Peruvian-bark, which now supersedes them perhaps too generally; for many cases of fever occur which are found to be aggravated by the Cinchona, yet afterwards readily yield to the simple bitters.--Woodville, p. 277.

190. COCHLEARIA officinalis. SCURVY-GRASS. The Herb. E.--Is antiseptic, attenuant, aperient, and diuretic, and is said to open obstructions of the viscera and remoter glands, without heating or irritating the system. It has long been considered as the most effectual of all the antiscorbutic plants; and its sensible qualities are sufficiently powerful to confirm this opinion. In the rheumatismus vagus, called by Sydenham Rheumatismus scorbuticus, consisting of wandering pains of long continuance, accompanied with fever, this plant, combined with Arum and Wood-Sorrel, is highly commended both by Sydenham and Lewis.

We have testimony of its great use in scurvy, not only from physicians, but navigators; as Anson, Linschoten, Maartens, Egede, and others. And it has been justly noticed, that this plant grows plentifully in those high latitudes where the scurvy is most obnoxious. Forster found it in great abundance in the islands of the South Seas.--Woodville, p. 395.

191. COCHLEARIA Armoracia. HORSE-RADISH. The Root. E.-The medical effects of this root are, to stimulate the solids, attenuate the juices, and promote the fluid secretions: it seems to extend its action through the whole habit, and affect the minutest glands. It has frequently done great service in some kinds of scurvies and other chronic disorders proceeding from a viscidity of the juices, or obstructions of the excretory ducts. Sydenham recommends it likewise in dropsies, particularly those which sometimes follow intermittent fevers. Both water and rectified spirit extract the virtues of this root by infusion, and elevate them in distillation: along with the aqueous fluid an essential oil arises, possessing the whole taste and pungency of the horse-radish. The College have given us a very elegant compound water, which takes its name from this root.

192. COLCHICUM autumnale. MEADOW-SAFFRON. The Roots. L. E. D.--The roots, freed from the outer blackish coat and fibres below, are white, and full of a white juice. In drying they become wrinkled and dark coloured. Applied to the skin, it shows some signs of acrimony; and taken internally, it is said sometimes to excite a sense of burning heat, bloody stools, and other violent symptoms. In the form of syrup, however, it has been given to the extent of two ounces a-day without any bad consequence. It is sometimes employed as a diuretic in dropsy. It is now supposed to be a principal ingredient in the celebrated French gout medicine L'Eau Medicinale.

193. CONIUM maculatum. HEMLOCK. The Leaves. L. E. D.--Physicians seem somewhat in dispute about the best mode of exhibiting this medicine; some recommending the extract, as being most easily taken in the form of pills; others the powder, as not being subject to that variation which the extract is liable to, from being made in different ways. With respect to the period, likewise, at which the plant should be gathered, they seem not perfectly agreed; some recommending it when in its full vigour, and just coming into bloom, and others, when the flowers are going off. An extract of the green plant is ordered by the College in their last list. Dr. Cullen has for many years commended the making it from the unripe seeds; and this mode the College of Physicians at Edinburgh have thought proper to adopt in their late Pharmacopoeia.

Similar Plants.--Aethusa Cynapium; Apium Petroselium; Oenanthe crocata; Oe. fistulosa; Phellandrium aquaticum.

194. CORIANDRUM sativum. CORIANDER. The Seeds. L. E. D.-These, when fresh, have a strong disagreeable smell, which improves by drying, and becomes sufficiently grateful. They are recommmended as carminative and stomachic.

195. CROCUS sativus. TRUE SAFFRON. The Stigmata. L. E. D.--There are three sorts of saffron met with in the shops, two of which are brought from abroad, the other is the produce of our own country. This last is greatly superior to the two former.

This medicine is particularly serviceable in hysteric depressions proceeding from a cold cause, or obstruction of the uterine secretions, where other aromatics, even those of the more generous kind, have little effect. Saffron imparts the whole of its virtue and colour to rectified spirit, proof spirit, wine, vinegar, and water: a tincture used to be drawn with vinegar, but it looses greatly its colour in keeping. There can be little use for preparations of saffron, as the drug itself will keep good for any length of time.

196. CUMINUM Cymini. CUMMIN. The Seeds. L.--Cummin seeds have a bitterish warm taste, accompanied with an aromatic flavour, not of the most agreeable kind. They are accounted good carminatives, but not very often made use of. An essential oil of them used to be kept in the shops, and they gave name to a plaster and cataplasm.--Lewis's Mat. Med.

197. CYNARA Scolymus. ARTICHOKE. The Leaves. E.--The bitter juice of the leaf, mixed with an equal part of Madeira wine, is recommended in an ounce dose night and morning, as a powerful diuretic in dropsy. An infusion of the leaf may likewise be used.

198. DAPHNE Mezereum. THE MEZEREON. The Roots. L. E. D.--This plant is extremely acrid, especially when fresh, and, if retained in the mouth, excites great and long continued heat and inflammation, particularly of the throat and fauces. The bark and berries of Mezereon in different forms have been long externally used to obstinate ulcers and ill conditioned sores. In France, the former is strongly recommended as an application to the skin, which, under certain management, produces a continued serious discharge without blistering, and is thus rendered useful in many chronic diseases of a local nature answering the purpose of what has been called a perpetual blister, while it occasions less pain and inconvenience.

In this country Mezereon is principally employed for the cure of some siphylitic complaints; and in this way Dr. Donald Monro was the first who gave testimony of its efficacy in the successful use of the Lisbon Diet Drink.

The considerable and long-continued heat and irritation that is produced in the throat when Mezereon is chewed, induced Dr. Withering to think of giving it in a case of difficulty of swallowing, seemingly occasioned by a paralytic affection. The patient was directed to chew a thin slice of the root as often as she could bear it, and in about a month recovered her power of swallowing. This woman had suffered the complaint three years, and was greatly reduced, being totally unable to swallow solids, and liquids but very imperfectly.--Woodville's Med. Bot. p. 720.

199. DATURA Stramonium. THORN APPLE. The whole Plant. E.--Dr. Woodville informs us, that an extract of this plant has been the preparation usually employed, and from one to ten grains and upwards a-day: but the powdered leaves after the manner of those directed for hemlock would seem, for the reason given, to be a preparation more certain and convenient.

It has been much celebrated as a medicine in epilepsy and convulsions and mania; but it is of a violent narcotic quality, and extremely dangerous in its effects.

Stramonium has been recommended, as being of considerable use in cases of asthma, on the authority of some eminent physicians of the East Indies; and the late Dr. Roxburgh has stated to me many instances wherein it had performed wonders in that dreadful malady.

The Datura Metal, Purple-flowered Thorn-apple, is much like the Stramonium, except in the flowers and the stalks being of a purple colour. I have made particular inquiry of Dr. Roxburgh if any particular kind was used in preference, and he said not; that both the above sorts were used; and, in fact, not only these, but the Datura Tatula, another species which grows wild there, and is cultivated in our stoves for the sake of its beautiful flowers, is also used for the same purposes.

The mode of using it was by cutting the whole plant up after drying, and smoking it in a common tobacco-pipe; and which, in some cases in this country also, has given great ease in severe attacks; and I know several persons who use it with good effect to this day. In vegetables of such powerful effects as this is known to have, great care ought to be taken in their preparation, which, I fear, is not always so much attended to as the nature of this subject requires [Footnote: See Observations on and Directions for preparing and preserving Herbs in general, et the end of this section.].

200. DAUCUS sylvestris. WILD CARROT. The Seeds. L.--These seeds possess, though not in a very considerable degree, the aromatic qualities common to those of the umbelliferous plants, and hence have long been deemed carminative and emmenagogue; but they are chiefly esteemed for their diuretic powers, and for their utility in calculus and nephritic complaints, in which an infusion of three spoonfuls of the seeds in a pint of boiling water has been recommended; or the seeds may be fermented in malt liquor, which receives from them an agreeable flavour resembling that of the lemon-peel.--Woodville's Med. Bot. p. 132.

Similar Plants.--Sison Amonum; Daucus Carota.

201. DAUCUS Carota. CULTIVATED CARROT. The Roots. L. E. D.--The expressed juice, or a decoction of these roots, has been recommended in calculous complaints, and as a gargle for infants in aphtous affections or excoriations of the mouth; and a poultice of scraped carrots has been found an useful application to phagedenic ulcers, and to cancerous and putrid sores.

202. DELPHINIUM Staphis Agria. STAVES AGRIA. The Seeds. L. D.-- Stavesacre was employed by the ancients as a cathartic, but it operates with so much violence both upwards and downwards, that its internal use has been, among the generality of practitioners, for some time laid aside. It is chiefly employed in external applications for some kinds of cutaneous eruptions; and for destroying lice and other insects; insomuch that it has from this virtue received its name in different languages, Herba pedicularis, Herbe aux poux, Lauskraut, Lousewort.

203. DIANTHUS caryophyllus. CLOVE-PINK. The Petals. E.--These flowers are said to be cardiac and alexipharmac. Simon Paulli relates, that he has cured many malignant fevers by the use of a de-coction of them; which he says powerfully promoted sweat and urine without greatly irritating nature, and also raised the spirits and quenched thirst. The flowers are chiefly valued for their pleasant flavour, which is entirely lost even by light coction. Lewis says, the College directed the syrup, which is the only officinal preparation of them, to be made by infusion.

204. DIGITALIS purpurea. FOXGLOVE. The Leaves. L. E. D.--The leaves of Foxglove have a nauseous taste, but no remarkable smell. They have been long used externally to sores and scrophulous tumours with considerable advantage. Its diuretic effects, for which it is now so deservedly received into the Materia Medica, were entirely overlooked. To this discovery Dr. Withering has an undoubted claim; and the numerous cures of dropsy related by him and other practitioners of established reputation, afford incontestable proofs of its diuretic powers, and of its practical importance in the cure of those diseases. The dose of dried leaves in powder is from one grain to three twice a-day; but if a liquid medicine be preferred, a dram of the dried leaves is to be infused for four hours in half a pint of boiling water, adding to the strained liquor an ounce of any spiritous water. One ounce of this infusion given twice a-day is a medium dose; it is to be continued in these doses till it either acts upon the kidneys; the stomach, or the pulse, (which it has a remarkable power of lowering,) or the bowels.-- Woodville's Med. Bot. p. 221.

This is now become a very popular medicine, but if used incautiously is attended with danger. Medical practitioners should make themselves perfectly acquainted with this plant, as the leaves are the only part used; and their not being readilly discriminated when separated from the flowers, several accidents have occurred. In the Gent. Mag. for September 1815 is recorded a very extraordinary mistake, where the life of a child was sacrificed to the ignorance of a person who administered this instead of Coltsfoot; a plant so very dissimilar, that, had it not been well authenticated, I should not have believed the fact.

Similar Plants.--Verbascum nigrum; V. Thapsus; Cynoglossum officinale, or, after the above mistake, any other plant with a lanceolate leaf, we fear, may be confounded with it.

205. ERYNGIUM maritimum. SEA-HOLLY. Roots. D.--The roots are slender, and very long; of a pleasant sweetish taste, which on chewing for some time is followed by a light degree of aromatic warmth and acrimony. They are accounted aperient and diuretic, and have also been celebrated as aphrodisiac: their virtues, however, are too weak to admit them under the head of medicines. The candied root is ordered to be kept in the shops.--Lewis's Mat. Med.

206. FERULA assafoetida. ASSAFOETIDA. Gum. L. E. D.--This drug has a strong fetid smell, somewhat like that of garlick; and a bitter, acrid, biting taste. It looses with age of its smell and strength, a circumstance to be particularly regarded in its exhibition. It consists of about one-third part pure resin, and two-thirds of gummy matter; the former soluble in rectified spirit, the other in water. Proof-spirit dissolves almost the whole into a turbid liquor; the tincture in rectified spirit is transparent.

Assafoetida is the strongest of the fetid gums, and of frequent use in hysteric and different kinds of nervous complaints. It is likewise of considerable efficacy in flatulent colics; and for promoting all the fluid secretions in either sex. The ancients attributed to this medicine many other virtues which are at present not expected from it.--Lewis's Mat. Med.

207. FICUS Carica. COMMON FIG. Fruit. L. D.--The recent fruit completely ripe is soft, succulent, and easily digested, unless eaten in immoderate quantities, when it is apt to occasion flatulency, pain of the bowels, and diarrhoea. The dried fruit is pleasanter to the taste, and is more wholesome and nutritive. Figs are supposed to be more nutritious by having their sugar united with a large portion of mucilaginous matter, which, from being thought to be of an oily nature, has been long esteemed an useful demulcent and pectoral; and it is chiefly with a view of these effects that they have been medicinally employed.

208. FRAXINUS Ornus. MANNA. L. E. D.--There are several sorts of Manna in the shops. The larger pieces, called Flake Manna, are usually preferred; though the smaller grains are equally as good, provided they are white, or of a pale yellow colour, very light, of a sweet not unpleasant taste, and free from any visible impurities.

Manna is a mild agreeable laxative, and may be given with saftey to children and pregnant women: nevertheless, in some particular constitutions it acts very unkindly, producing flatulencies and distension of the viscera.--Lewis's Mat. Med.

209. GENTIANA lutea. YELLOW GENTIAN. Root. L. D.--This root is a strong bitter, and, as such, very frequently made use of in practice: in taste it is less exceptionable than most of the other substances of this class: infusions of it, flavoured with orange peel, are sufficiently grateful. It is the capital ingredient in the bitter wine; and a tincture and infusion of it are kept in the shops.

Lewis mentions a poisonous root being mixed among some of the Gentian brought to London; the use of which occasioned in some instances death. This was internally of a white colour, and void of bitterness. There is no doubt but this was the root of the Veratrum album, a poisonous plant so similar, that it might readily be mistaken for it.--Lewis's Mat. Med.

210. GEUM urbanum. COMMON AVENS. Root. D.--This has a warm, bitterish, astringent taste, and a pleasant smell, somewhat of the clove kind, especially in the spring, and when produced in dry warm soils. Parkinson observes, that such as is the growth of moist soils has nothing of this flavour. This root has been employed as a stomachic, and for strengthening the tone of the viscera in general: it is still in some esteem in foreign countries, though not taken notice of among us. It yields, on distillation, an elegant odoriferous essential oil, which concretes into a flaky form.--Lewis's Mat. Med.

Similar Plants.--Geum rivale; G. intermedium.

211. GLYCYRRHIZA glabra. LIQUORICE. Root. L. D.--This is produced plentifully in all the countries of Europe: that which is the growth of our own is preferable to such as comes from abroad; this last being generally mouldy, which this root is very apt to become, unless kept in a dry place.

The powder of liquorice usually sold is often mingled with flower, and, I fear, too often with substances not quite so wholesome. The best sort is of a brownish yellow colour (the fine pale yellow being generally sophisticated) and of a very rich sweet taste, much more agreeable than that of the fresh root. Liquorice is almost the only sweet that quenches thirst.

This root is a very useful pectoral, and excellently softens acrimonious humours, at the same time that it proves gently detergent: and this account is warranted by experience. It is an ingredient in the pectoral syrup, pectoral troches, the compound lime waters, decoction of the woods, compound powder of gum tragacanth, lenitive electuary, and theriaca. An extract is directed to be made from it in the shops; but this preparation is brought chiefly from abroad, though the foreign extract is not equal to such as is made with proper care among ourselves.--Lewis's Mat. Med.

212. GRATIOLA officinalis. HEDGE-HYSSOP. Herb. E. D.--The leaves have a very bitter disagreeable taste: an infusion of a handful of them when fresh, or a dram when dried, is said to operate strongly as a cathartic. Kramer reports that he has found the root of this plant a medicine similar in virtue to Ipecacuanha.

Similar Plants.--Lythrum Salicaria; Scutellaria galericulata.

213. HELLEBORUS niger. BLACK HELLEBORE. Root. L.--The tase of Hellebore is acrid and bitter. Its acrimony, as Dr. Grew observes, is first felt on the tip of the tongue, and then spreads immediately to the middle, without being much perceived on the intermediate part: on chewing it for a few minutes, the tongue seems benumbed, and affected with a kind of paralytic stupor, as when burnt by eating any thing too hot.

Our Hellebore is at present looked upon principally as an alterative, and in this light is frequently employed, in small doses, for attenuating viscid humours, promoting the uterine and urinary discharges, and opening inveterate obstructions of the remoter glands: it often proves a very powerful emmenagogue in plethoric habits, where steel is ineffectual or improper. An extract made from this root with water, is one of the mildest, and for the purposes of a cathartic the most effectual preparation of it: this operates sufficiently, without occasioning the irritation which the pure resin is accompanied with. A tincture drawn with proof-spirit contains the whole virtue of the Hellebore, and seems to be one of the best preparations of it: this tincture, and the extract, used to be kept in the shops. The College of Edinburgh used to make this root an ingredient in the purging cephalic tincture, and compound tincture of jalap; and its extract, in the purging deobstruent pills, gamboge pills, the laxative mercurial pills, and the compound cathartic extract.--Lewis's Mat. Med.

Similar Plant.--Helleborus viridis.

214. HELLEBORUS foetidus. BEARSFOOT. Leaves. L.--The root is a strong cathartic; it destroys worms, and is recommended in different species of mania. It is commonly substituted for that of the Helleborus viridis, which is a more dangerous medicine. Hill's Herbal, p. 32. Great care ought to be used in the administering this plant: many instances of its dreadful effects are related. (See Poisonous Plants.)

Similar Plant.--Helleborus viridis.

215. HORDEUM distichon. PEARL BARLEY. Seeds. L. E.--Barley, in its several states, is more cooling, less glutionous, and less nutritious than wheat or oats; among the ancients, decoctions of it were the principal aliment, and medicine, in acute diseases. The London College direct a decoction of pearl barley; and both the London and Edinburgh make common barley an ingredient in the pectoral decoction.

216. HUMULUS Lupulus. THE HOP.--The flowers and seed-vessels are used in gout and rheumatism, under the form of infusion in boiling-water. The powder formed into an ointment with lard, is said to ease the pain of open cancer. A pillow stuffed with hops is an old and successful mode of procuring sleep in the watchfulness of delirious fever.

217. HYOSCYAMUS niger. HENBANE. Leaves and Seeds. L. E.--Henbane is a strong narcotic poison, and many instances of its deleterious effects are recorded by different authors; from which it appears, that any part of the plant, when taken in sufficient quantity, is capable of producing very dangerous and terrible symptoms. It is however much employed in the present days as an anodyne. Dr. Withering found it of great advantage in a case of difficult deglutition. Stoerck and some others recommend this extract in the dose of one grain or two; but Dr. Cullen observes, that he seldom discovered its anodyne effects till he had proceeded to doses of eight or ten grains, and sometimes to fifteen and even to twenty. The leaves of Henbane are said to have been applied externally with advantage, in the way of poultice, to resolve scirrhous tumours, and to remove some pains of the rheumatic and arthritic kind.

Similar Plants.--Verbascum Lychnites; V. nigrum.

The roots of the Henbane are to be distinguished by their very powerful and narcotic scent.

218. HYSSOPUS officinalis. HYSSOP. The Herb. L. E. D.--The leaves of Hyssop have an aromatic smell, and a warm pungent taste. Besides the general virtues of aromatics, they are particularly recommeded in humoral asthmas, coughs, and other disorders of the breast and lungs; and said to notably promote expectoration.
