173. ANTHEMIS Pyrethrum. PELLITORY OF SPAIN. The Root. L.—The principal use of Pyrethrum in the present practice is as a masticatory, for promoting the salival flux, and evacuating viscid humours from the head and neighbouring parts: by this means it very generally relieves the tooth-ach, pains of the head, and lethargic complaints. If a piece of the root, the size of a pea, be placed against the tooth, it instantly causes the saliva to flow from the surrounding glands, and gives immediate relief in all cases of that malady.
174. APIUM Petroselium. COMMON PARSLEY. The Root. E.—Both the roots and seeds of Parsley are directed by the London College for medicinal use: the former have a sweetish taste, accompanied with a slight warmth of flavour somewhat resembling that of a carrot; the latter are in taste warmer and more aromatic than any other part of the plant, and also manifest considerable bittenress.
These roots are said to be aperient and diuretic, and have been employed in apozems to relieve nephritic pains, and obstructions of urine.
Although Parsley is commonly used at table, it is remarkable that facts have been adducted to prove, that in some constitutions it occasions epilepsy, or at least aggravates the epileptic fit in those who are subject to this disease. It has been supposed also to produce inflammation in the eyes.—Woodville's Med. Bot. p. 43. A variety which produces larger roots, called Hamburgh Parsley, is commonly grown for medicinal uses.
175. ARBUTUS Uva Ursi. TRAILING ARBUTUS or BEAR-BERRY. The Leaves.—This first drew the attention of physicians as an useful remedy in calculous and nephritic affections; and in the years 1763 and 1764, by the concurrent testimonies of different authors, it acquired remarkable celebrity, not only for its efficacy in gravelly complaints, but in almost every other to which the urinary organs are liable, as ulcers of the kidneys and bladder, cystirrhoea, diabetes, &c. It may be employed either in powder or decoction; the former is most commonly preferred, and given in doses from a scruple to a dram two or three times a-day.— Woodville's Med. Botany.
176. ARNICA montana. MOUNTAIN ARNICA. The whole Plant. E. D.—The odour of the fresh plant is rather unpleasant, and the taste acrid, herbaceous, and astringent; and the powdered leaves act as a strong sternutatory.
This plant, according to Bergius, is an emetic, errhine, diuretic, diaphoretic, emmenagogue; and from its supposed power of attenuating the blood, it has been esteemed so peculiarly efficacious in obviating the bad consequences occasioned by falls and bruises, that it obtained the appellation of Panacea Lapsorum.—Woodville's Med. Bot. p. 43.
177. ARTEMISIA Absinthium. WORMWOOD, The Herb. L.—Wormwood is a strong bitter; and was formerly much used as such against weakness of the stomach, and the like, in medicated wines and ales. At present it is rarely employed in these intentions, on account of the ill relish and offensive smell which it is accompanied with. These it may be in part freed from by keeping, and totally by long coction, the bitter remaining entire. An extract made by boiling the leaves in a large quantity of water, and evaporating the liquor with a strong fire, proves a bitter sufficiently grateful, without any disgustful flavour.
178. ARTEMISIA Abrotanum. SOUTHERNWOOD. Leaves. D.—Southernwood has a strong, not very disagreeable smell; and a nauseous, pungent, bitter taste; which is totally extracted by rectified spirit, less perfectly by watery liquors. It is recommended as an anthelmintic; and in cold lencophlegmatic habits, as a stimulant, detergent, aperient, and sudorific. The present practice has almost entirely confined its use to external applications. The leaves are frequently employed in discutient and antiseptic fomentations; and have been recommended also in lotions and unguents for cutaneous eruptions, and the falling off of the hair.
179. ARTEMISIA maritima. SEA WORMWOOD. Tops. D.—In taste and smell, it is weaker and less unpleasant than the common worm-wood. The virutes of both are supposed to be of the same kind, and to differ only in strength.
