286. VERATRUM album. WHITE HELLEBORE. Root. L. E. D.-The root has a nauseous, bitterish, acrid taste, burning the mouth and fauces: wounded when fresh, it emits an extremely acrimonious juice, which mixed with the blood, by a wound, is said to prove very dangerous: the powder of the dry root, applied to an issue, occasions violent purging: snuffed up the nose, it proves a strong, and not always a safe, sternutatory. This root, taken internally, acts with extreme violence as an emetic, and has been observed, even in a small dose, to occasion convulsions and other terrible disorders. The ancients sometimes employed it in very obstinate cases, and always made this their last resource.

287. VERONICA Beccabunga. BROOKLIME. Herb. L. D.—This plant was formerly considered of great use in several diseases, and was applied externally to wounds and ulcers; but if it have any peculiar efficacy, it is to be derived from its antiscorbutic virtue.
As a mild refrigerant juice, it is preferred where an acrimonious state of the fluids prevails, indicated by prurient eruptions upon the skin, or in what has been called the hot scurvy.—Woodville's Med. Bot. 364.
288. VITIS vinifera. GRAPE VINE. Raisins and different Wines. L. E.— These are to cheer the spirits, warm the habit, promote perspiration, render the vessels full and turgid, raise the pulse, and quicken the circulation. The effects of the full-bodied wines are much more durable than those of the thinner; all sweet wines, as Canary, abound with a glutinous nutritious substance; whilst the others are not nutrimental, or only accidentally so by strengthening the organs employed in digestion: sweet wines in general do not pass off freely by urine, and heat the constitution more than an equal quantity of any other, though containing full as much spirit: red port, and most of the red wines, have an astringent quality, by which they strengthen the tone of the stomach and intestines, and thus prove serviceable for restraining immoderate secretions: those which are of an acid nature, as Renish, pass freely by the kidneys, and gently loosen the belly: it is supposed that these last exasperate, or occasion gout and calculous disorders, and that new wines of every kind have this effect.
The ripe fruit of grapes, of which there are several kinds, properly cured and dried, are the raisins and currants of the shops: the juice of these also, by fermentation, affords wine as well as vinegar and tartar.
The medical use of raisins is, their imparting a very pleasant flavour both to aqueous and spiritous menstrua. The seeds or stones are supposed to give a disagreeable relish, and hence are generally directed to be taken out: nevertheless I have not found that they have any disagreeable taste.—Lewis's Mat. Med.
289. ULMUS campestris. ELM. Bark. L. E. D.—The leaves have a bitterish astringent taste, and are recommended in powder, to the extent of at least two drams a-day, in ulcerations of the urinary passages and catarrhus vesicae. The powder has been used with opium, the latter being gradually increased to a considerable quantity, in diabetes, and it is said with advantage. Some use it for alleviating the dyspeptic symptoms in nephritic calculous ailments.—Lewis's Mat. Med.
290. RHODODENDRON Chrysanthemum. YELLOW-FLOWERED RHO-DODENDRON. E. The Leaves.—This species of Rhododendron has lately been introduced into Britain: it is a native of Siberia, affecting mountainous situations, and flowering in June and July.
Little attention was paid to this remedy till the year 1779, when it was strongly recommended by Koelpin as an efficacious medicine, not only in rheumatism and gout, but even in venereal cases; and it is now very generally employed in chronic rheumatisms in various parts of Europe. The leaves, which are the part directed for medicinal use, have a bitterish subastringent taste, and, as well as the bark and young branches, manifest a degree of acrimony. Taken in large doses they prove a narcotic poison, producing those symptoms which we have described as occasioned by many of the order Solanaceae.
