The waste lands on Hindhead and Blackdown in Surry and Suss.e.x are noticed for producing this fruit, which is similar to Black Currants.

They are gathered in the months of August and September, and sold at the neighbouring markets.

In a calculation of the value of this plant with an intelligent nurseryman in that county, we found that from 500 l. to 700 l. were earned and realized annually by the neighbouring poor, who employed their families in this labour, and who are in the habit of travelling many miles for this purpose. The fruit is ripe in August, and at that season is met with in great plenty in all the neighbouring towns.

155. VISc.u.m alb.u.m. MISSELTO.--A parasitical plant well known, and formerly of much repute in medicine, but wholly disregarded in the present practice. Birdlime is made from the berries.

Dr. Pulteney in tracing the history of Botanic science quotes Pliny for an account of the veneration in which this plant was held by the Druids, who attributed almost divine efficacy to it, and ordained the collecting it with rites and ceremonies not short of the religious strictness which was countenanced by the superst.i.tion of the age. It was cut with a golden knife, and when the moon was six days old gathered by the priest, who was clothed with white for the occasion, and the plant received on a white napkin, and two white bulls sacrificed. Thus consecrated, Misselto was held to be an antidote to poison, and prevented sterility. Query, Has not the custom of hanging up Misselto at merry-makings, and the ceremony so well known among our belles, some relation to above sacrifice?

156. ULEX europaeus. COMMON FURZE.--The culture of this shrub is given in the Agricultural Plants, being good for feeding cattle; its princ.i.p.al use however is for fuel, and it is frequently grown for such purposes.

It is common on most of our waste lands. It also forms good fences, but should always be kept short and young, otherwise it becomes thin, especially in good land where it grows up and makes large bushes.

157. ULMUS campestris. THE ELM.--We have a number of varieties of the Elm; the most esteemed is that with the smooth bark. The timber has been long in request for water-pipes, and for boards, which are converted into various uses in domestic oeconomy.

158. ULMUS montana. BROAD-LEAVED ELM.--This has not been considered of so great value as the common sort, but it is of much more free growth; and I have been informed that in the West of England the timber has been found to be good and lasting.

SECT. VII.--PLANTS USEFUL IN MEDICINE.

The initial letters in this cla.s.s distinguish the Pharmacopoeia in which each plant is inserted.

"By the wise and unchangeable laws of Nature established by a Being infinitely good and infinitely powerful,--not only man, the lord of the creation, 'fair form who wears sweet smiles, and looks erect on heaven,'

but every subordinate being becomes subject to decay and death: pain and disease, the inheritance of mortality, usually accelerate his dissolution. To combat these, to alleviate when it has not the power to avert, Medicine, honoured art! comes to our a.s.sistance.

"It will not be expected that we should here give a history of this ancient practice, or draw a parallel betwixt the success of former physicians and those of modern times: all that concerns us to remark is, that the ancients were infinitely more indebted to the vegetable kingdom for the materials of their art than the moderns. Not so well acquainted with the oeconomy of nature, which teaches us that plants were chiefly destined for the food of various animals, they sought in every herb some latent healing virtue, and frequently endeavoured to make up the want of efficacy in one by the combination of numbers: hence the extreme length of their farraginous prescriptions. More enlightened ideas of the operations of medicine have taught the moderns greater simplicity and conciseness in practice. Perhaps there is a danger that this simplicity may be carried to far, and become finally detrimental to the practice."

The above is quoted from the Preface to a Catalogue of Medicinal Plants published by my predecessor in 1783: and it may be observed, that the medical student has, at the present season, a still less number of plants to store up in memory, owing, probably, to the great advances that chemistry has made in the mean time, through which mineral articles in many instances have superseded those of the vegetable kingdom. But, nevertheless, as Dr. Woodville has justly observed, "it would be difficult to show that this preference is supported by any conclusive reasoning drawn from a comparative superiority of the former;" or that the more general use of them has led to greater success in the practice of the healing art. It is however evident, that we have much to regret the almost total neglect of the study of medical botany by the younger branches of the professors of physic, when we are credibly informed that Cow-parsley has been administered for Hemlock, and Foxglove has been subst.i.tuted for Coltsfoot [Footnote: See the account of a dreadful accident of this nature, in Gent. Mag. for Sept. 1815.], from which circ.u.mstance, some valuable lives have been sacrificed. It is therefore high time that those persons who are engaged in the business of pharmacy should be obliged to become so far acquainted with plants, as to be able to distinguish at sight all such as are useful in diet or medicine, and more particularly such as are of poisonous qualities.

The medical student has so many subjects for his consideration, that it is not desirable he should have a greater number of vegetables to consult than are necessary. And we cannot help lamenting the difficulty he has to struggle with in consequence of the great difference of names which the Pharmacopoeias of the present day exhibit. The London, Edinburgh, and Dublin, in many instances, enforce the necessity of learning a different term in each for the same thing, and none of which are called by the same they were twenty years ago. Surely it would be the means of forwarding the knowledge of drugs, if each could be distinguished by one general term.

The candidate for medical knowledge, however, is not the only one who has at times to regret this confusion of names. The Linnaean system is an easy and delightful path to the knowledge of plants; but, like all other human structures, it has its imperfections, and some of which have been modified by judicious alterations. Yet the teachers of this science, as well as the students, have often to deprecate the unnecessary change in names which has been made by many writers, though., in many cases, no more reason appears for it than there generally would be to change Christian and surnames of persons.

In the following section, I shall enumerate and describe those plants which are contained in the lists of the three colleges; and afterwards a separate list of those which, although they have been expunged, are still sometimes used by medical men.

I shall also endeavour to give such descriptions as are concise, at the same time sufficient for general knowledge, and for which reason I have taken Lewis's Materia Medica for my text, unless where improvements have been made in certain subjects I have consulted more modern authorities.

It should be observed, that writers on medical plants, with few exceptions, have copied from one another: or with a little alteration as to words only.

And as some vegetables, from their affinitiy, may be confounded with others, whereby those possessing medical qualities may be subst.i.tuted for others having none, or even poisonous ones, I shall in some instances enumerate a list of similar plants, which, with attention to their botanical characters, it is hoped will prevent those dangerous errors we have lately witnessed. As it is our business, in demonstrating plants, to guard the student against such confusion, it will be proper that specimens of such as come under this head be preserved, as a work for reference and contrast wherever doubts may arise.

158. ACONITUM Napellus. COMMON BLUE MONKSHOOD. The Leaves. L. E.--Every part of the fresh plant is strongly poisonous, but the root is unquestionably the most powerful, and when chewed at first imparts a slight sensation of acrimony, and a pungent heat of the lips, gums, palate and fauces, which is succeeded by a general tremor and sensation of chilliness.

This plant has been generally prepared as an extract or insp.i.s.sated juice, after the manner directed in the Edinburgh and many of the foreign Pharmacopoeias, and, like all virulent medicines, it should be first administered in small doses. Stoerck recommends two grains of the extract to be rubbed into a powder with two drums of sugar, and as a dose to begin with ten grains of this powder two or three times a-day.

Similar Plants.--Aconitum j.a.ponic.u.m; A. pyrenaic.u.m; Delphinium elatum; D. exallatum.

Instead of the extract, a tincture has been made of the dried leaves macerated in six times their weight of spirit of wine, and forty drops given for a dose.--Woodville's Med. Bot. 965.

The Dublin College has ordered the Aconitum Neomontanum, which is not common in this country [Footnote: In plants of so very poisonous a nature as the Aconite, it is the duty of every one who describes them to be particular. Here seems to have been a confusion. The A. Neomontanum is figured in Jacquin's Fl. Austriaca, fasc. 4. p. 381; and the first edition of Hortus Kewensis under A. Napellus erroneously quotes that figure: but both Gmelin in Syst. Vegetabilium, p. 838, and Wildenow in Spec. Plant. p. 1236, quote it under its proper name, A. Neomontanum.

Now the fact is, that the Napellus is the Common Blue Monkshood; and the Neomontanum is altogether left out of the second edition of the Hortus Kewensis for the best of all reasons, it is not in this country; or, if it is, it must be very scarce, and, of course, not the plant used in medicine.].

160. ACORCUS Calamus. SWEET RUSH. The Root. L.--It is generally looked upon as a carminative and stomachic medicine, and as such is sometimes made use of in practice. It is said by some to be superior in aromatic flavour to any other vegetable that is produced in these northern climates; but such as I have had an opportunity of examining, fell short, in this respect, of several of our common plants. It is, nevertheless, a sufficiently elegant aromatic. It used to be an ingredient in the Mithridate and Theriaca of the London Pharmacopoeia, and in the Edinburgh. The fresh root candied after the manner directed in our Dispensatory for candying eryngo root, is said to be employed at Constantinople as a preservative against epidemic diseases. The leaves of this plant have a sweet fragrant smell, more agreeable, though weaker, than that of the roots.--Lewis's Mat. Med.

161. AESCULUS Hippocastanum. HORSE-CHESNUT. The Bark and Seed. E. D.-- With a view to its errhine power, the Edinburgh College has introduced the seeds into the Materia Medica, as a small portion of the powder snuffed up the nostrils readily excites sneezing; even the infusion or decoction of this fruit produces this effect; it has therefore been recommended for the purpose of producing a discharge from the nose, which, in some complaints of the head and eyes is found to be of considerable benefit.

On the continent, the Bark of the Horse Chesnut-tree is held in great estimation as a febrifuge; and, upon the credit of several respectable authors, appears to be a medicine of great efficacy.--Woodville's Med.

Bot. 615.

162. AGRIMONIA Eupatoria. COMMON AGRIMONY. The Herb. D.--The leaves have an herbaceous, somewhat acrid, roughish taste, accompanied with an aromatic flavour. Agrimony is said to be aperient, detergent, and to strengthen the tone of the viscera: hence it is recommended in s...o...b..tic disorders, in debility and laxity of the intestines, &c. Digested in whey, it affords an useful diet-drink for the spring season, not ungrateful to the palate or stomach.

163. ALLIUM Porrum. LEEK. The Root. L.--This partic.i.p.ates of the virtues of garlic, from which it differs chiefly in being much weaker. See the article ALLIUM.

164. ALLIUM sativum. GARLIC. The Root. L. E. D.--This pungent root warms and stimulates the solids, and attenuates tenacious juices. Hence in cold leucophelgmatic habits it proves a powerful expectorant, diuretic, and emmenagogue; and, if the patient is kept warm, sudorific. In humoral asthmas, and catarrhous disorders of the breast, in some scurvies, flatulent colics, hysterical and other diseases proceeding from laxity of the solids, and cold sluggish indisposition of the fluids, it has generally good effects: it has likewise been found serviceable in some hydropic cases. Sydenham relates, that he has known the dropsy cured by the use of garlic alone; he recommends it chiefly as a warm strengthening medicine in the beginning of the disease.

Garlic made into an unguent with oils, &c. and applied externally, is said to resolve and discuss cold tumors, and has been by some greatly esteemed in cutaneous diseases. It has likewise sometimes been employed as a repellent. Sydenham a.s.sures us, that among all the substances which occasion a derivation or revulsion from the head, none operate more powerfully than garlic applied to the soles of the feet: hence he was led to make use of it in the confluent small-pox about the eighth day, after the face began to swell; the root cut in pieces, and tied in a linen cloth, was applied to the soles, and renewed once a day till all danger was over.

165. ALLIUM Cepa. ONION. The Root. D.--These roots are considered rather as articles of food than of medicine: they are supposed to afford little or no nourishment, and when eaten liberally they produce flatulencies, occasion thirst, headachs, and turbulent dreams: in cold phlegmatic habits, where viscid mucus abounds, they doubtless have their use; as by their stimulating quality they tend to excite appet.i.te, attenuate thick juices, and promote their expulsion: by some they are strongly recommended in suppressions of urine and in dropsies. The chief medicinal use of onions in the present practice is in external applications, as a cataplasm for suppurating tumours, &c.

166. ALTHAEA officinalis. MARSH-MALLOW. The Leaves and Root. L.--This plant has the general virtues of an emollient medicine; and proves serviceable in a thin acrimonious state of the juices, and where the natural mucus of the intestines is abraded. It is chiefly recommended in sharp defluxions upon the lungs, hoa.r.s.eness, dysenteries, and likewise in nephritic and calculous complaints; not, as some have supposed, that this medicine has any peculiar power of dissolving or expelling the calculus; but as, by lubricating and relaxing the vessels, it procures a more free and easy pa.s.sage. Althaea root is sometimes employed externally for softening and maturing hard tumours: chewed, it is said to give ease in difficult dent.i.tion of children.
