A medicinal tincture is prepared (H.) from the kernel with spirit of wine (not using the oil, nor the essence). This in small diluted doses is highly useful for drowsiness connected with flatulent indigestion, and a disposition to faintness: also for gout retrocedent to the stomach. The dose is from five to ten drops with a spoonful of water every half hour, or every hour until the symptoms are adequately relieved. Against diarrhoea Nutmeg grated into warm water is very helpful, and will prove an efficient substitute for opium in mild cases. Externally the spirit of Nutmeg is a capital application to be rubbed in for chronic rheumatism, and for paralysed limbs. The "butter of Nutmegs," or their concrete oil, is used in making plasters of a warming, and stimulating kind. A drink that was concocted by our grandmothers was Nutmeg tea. One Nutmeg would make a pint of this tea, two or three cupfuls of which would produce a sleep of many hours' duration. The worthy old ladies were wont to carry a silver grater and Nutmeg case suspended from the waist on their chatelaines. But in any large quantity the Nutmeg may produce sleep of such a profundity as to prove really dangerous. Two drachms of the powder have brought on a comatose sleep with some delirium.
[395] The Nutmeg contains starch, protein, and other simple constituents, in addition to its stimulating principles. Mace is the aromatic envelope of the Nutmeg, and possesses the same qualities in a minor degree. Its infusion is a good warming medicine against chronic cough, and moist bronchial asthma in an old person. Mace is a membranaceous structure enveloping the Nutmeg, having a fleshy texture, and being of a light yellowish-brown colour. It supplies an allied essential volatile principle, which is fragrant and cordial. If given three or four times during the twenty-four hours, in a dose of from eight to twelve grains, crushed, or powdered Mace will prove serviceable against long-continued looseness of the bowels; but this dose should not be exceeded for fear of inducing narcotism.
Cloves (from clavus, a nail), also found in the kitchen spice box, and owning certain medicinal resources of a cordial sort, which are quickly available, belong to the Myrtle family of plants, and are the unexpanded flower buds of an aromatic tree (Caryophyllus), cultivated at Penang and elsewhere. They contain a volatile oil which, like that of Chamomile, although cordial, lowers nervous sensibility, or irritability: also tannin, a gum resin, and woody fibre. This volatile oil consists principally of "eugenin" with a camphor, "caryophyllin." The "eugenic acid," with a strong odour of cloves, is powerfully antiseptic and anti-putrescent. It reduces the sensibility of the skin: and therefore the oil with lanolin is a useful application for eczema.
Dr Burnett has lately taught (1895) that a too free use of Cloves will bring on albuminuria; and that when this disease has supervened from other causes, the dilute tincture of Cloves, third decimal strength, will frequently do much to lessen the quantity of albumen [396] excreted by the kidneys. From five to ten drops of this tincture should be given with water three times a day.
Used in small quantities as a spice the Clove stimulates digestion, but when taken more freely it deadens the susceptibility of the stomach, lessens the appetite, and induces constipation. An infusion of Cloves, made with half an ounce to a pint of water, and drank in doses of a small wineglassful, will relieve the nausea and coldness of flatulent indigestion. The oil put on cotton wool into the hollow of a decayed tooth is a useful means for giving ease to toothache. The dose of the oil is from one to five drops, on sugar, or in a spoonful of milk. The odour of Cloves is aromatic, and the taste pleasantly hot, but acrid. Half a tumbler of quite hot water poured over half a dozen Cloves (which are to brew for a few minutes on the hob, and then to be taken out), will often secure a good night to a restless dyspeptic patient, if taken just before getting into bed. Or if given cold before breakfast this dose will obviate constipation. In Holland the oil of Cloves is prescribed with cinchona bark for ague. Arthur Cecil's German medico in the Play advises his patient to "rub your pelly mit a Clove."
All-Spice (Pimento) is another common occupant of the domestic spice box. It is popular as a warming cordial, of a sweet odour, and a grateful aromatic taste; but being a native of South America, grows with us only as a stove plant. The leaves and bark are full of inflammable particles, whilst walks between Pimento trees are odorous with a delicious scent. The name All-Spice is given because the berries afford in smell and taste a combination of Cloves, Juniper berries, Cinnamon and Pepper. The special qualities of the Pimento reside in the rind of these berries; and this tree is the Bromelia ananas, [397] named in Brazil Nana. An extract made from the crushed berries by boiling them down to a thick liquor, is, when spread on linen, a capital stimulating plaster for neuralgic or rheumatic parts. About the physician in "les Francais" it was said admiringly "c'est lui qui a inventé la salade d'Ananas." The essential oil, as well as the spirit and the distilled water of Pimento, are useful against flatulent indigestion and for hysterical paroxysms. This Spice was formerly added to our syrup of buckthorn to prevent it from griping. The berries are put into curry powder, and added to mulled wines.
OAT.
The Oat is a native of Britain in its wild and uncultivated form, and is distinguished by the spikelets of its ears hanging on slender pedicels. This is the Avena fatua, found in our cornfields, but not indigenous in Scotland. When cultivated it is named Avena sativa. As it needs less sunshine and solar warmth to ripen the grain than wheat, it furnishes the principal grain food of cold Northern Europe. With the addition of some fat this grain is capable of supporting life for an indefinite period. Physicians formerly recommended highly a diet-drink made from Oats, about which Hoffman wrote a treatise at the end of the seventeenth century; and Johannis de St. Catherine, who introduced the drink, lived by its use to a hundred years free from any disease. Nevertheless the Oat did not enjoy a good reputation among the old Romans; and Pliny said "Primum omnis frumenti vitium avena est."
American doctors have taken of late to extol the Oat (Avena sativa) when made into a strong medicinal tincture with spirit of wine, as a remarkable nervine stimulant and restorative: this being "especially valuable in [398] all cases where there is a deficiency of nervous power, for instance, among over-worked lawyers, public speakers, and writers."
The tincture is ordered to be given in a dose of from ten to twenty drops, once or twice during the day, in hot water to act speedily; and a somewhat increased dose in cold water at bedtime so as to produce its beneficial effects more slowly then. It proves an admirable remedy for sleeplessness from nervous exhaustion, and as prepared in New York may be procured from any good druggist in England. Oatmeal contains two per cent. of protein compounds, the largest portion of which is avenin. A yeast poultice made by stirring Oatmeal into the grounds of strong beer is a capital cleansing and healing application to languid sloughing sores.
