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 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.

Oatmeal supplies very little saccharine matter ready formed. It cannot be made into light bread, and is therefore prepared when baked in cakes; or, its more popular form for eating is that of porridge, where the ground meal becomes thoroughly soft by boiling, and is improved in taste by the addition of milk and salt. "The halesome parritch, chief of Scotia's food," said Burns, with fervid eloquence. Scotch people actually revel in their parritch and bannocks. "We defy your wheaten bread," says one of their favourite writers, "your home-made bread, your bakers' bread, your baps, rolls, scones, muffins, crumpets, and cookies, your bath buns, and your sally luns, your tea cakes, and slim cakes, your saffron cakes, and girdle cakes, your shortbread, and singing hinnies: we swear by the Oat cake, and the parritch, the bannock, and the brose." Scotch beef brose is made by boiling Oatmeal in meat liquor, and kail brose by cooking Oatmeal in cabbage-water. Crushed Oatmeal, from which the husk has been removed, is known as "groats," and is employed for making gruel. At the latter end of the seventeenth century this was a drink asked-for eagerly by the public at London taverns. "Grantham gruel," says quaint old Fuller, in his History of the Worthies of England, "consists of nine grits and a gallon of water." When "thus made, it is wash rather, which one will have little heart to eat, and yet as little heart by eating." But the better gruel concocted elsewhere was "a wholesome Spoon meat, though homely; physic for the sick, and food for persons in health; grits the form thereof: and giving the being thereunto." In the border forays of the twelfth and thirteenth centuries all the provision carried by the Scotch was simply a bag of Oatmeal. But as a food it is apt to undergo some fermentation in the stomach, and to provoke sour eructations. Furthermore, it is somewhat laxative, because containing a certain proportion of bran which mechanically stimulates the intestinal membranes: and this insoluble bran is rather apt to accumulate. Oatmeal gruel may be made by boiling from one to two ounces of the meal with three pints of water down to two pints, then straining the decoction, and pouring off the supernatant liquid when cool. Its flavour may be improved by adding raisins towards the end of boiling, or by means of sugar and nutmeg. Because animals of speed use up, by the lungs, much heat-forming material, Oats (which abound in carbonaceous constituents) are specially suitable as food for the horse.

Though not of native British growth, except by way of a luxury in the gardens of the wealthy, yet the Orange is of such common use amongst all classes of our people as a dietetic fruit, when of the sweet China sort, and for tonic medicinal purposes when of the bitter Seville kind, that some consideration may be fairly accorded to it as a Curative Simple in these pages.

The Citrus aurantium, or popular Orange, came originally from India, and got its distinctive title of Aurantium, either (ab aureo colore corticis) from the golden colour of its peel, or (ab oppido Achoeioe Arantium) from Arantium, a town of Achaia. It now comes to us chiefly from Portugal and Spain. This fruit is essentially a product of cultivation extending over many years. It began in Hindustan as a small bitter berry with seeds; then about the eighth century it was imported into Persia, though held somewhat accursed. During the tenth century it bore the name "Bigarade," and became better known. But not until the sixteenth century was it freely grown by the Spaniards, and brought into Mexico. Even at that time the legend still prevailed that whoever partook of the luscious juice was compelled to embrace the faith of the prophet. Spenser and Milton tell of the orange as the veritable golden apple presented by Jupiter to Juno on the day of their nuptials: and hence perhaps arose its more modern association with marriage rites.

Of the varieties the China Orange is the most juicy, being now grown in the South of Europe; whilst the St. Michael Orange (a descendant of the China sort, first produced in Syria), is now got abundantly from the Azores, whence it derives its name.

John Evelyn says the first China Orange which appeared in Europe, was sent as a present to the old Condé Mellor; then Prime Minister to the King of Portugal, when only one plant escaped sound and useful of the whole case which reached Lisbon, and this became the parent of all the Orange trees cultivated by our gardeners, though not without greatly degenerating.

The Seville Orange is that which contains the medicinal properties, more especially in its leaves, flowers, and fruit, though the China sort possesses the same virtues in a minor degree. The leaves and the flowers have been esteemed as beneficial against epilepsy, and other convulsive disorders; and a tea is infused from the former for hysterical sufferers.

Two delicious perfumes are distilled from the flowers--oil of neroli, and napha water,--of which the chemical hydro-carbon "hesperidin," is mainly the active principle. This is secreted also as an aromatic attribute of the leaves through their minute glands, causing them to emit a fragrant odour when bruised. A scented water is largely prepared in France from the flowers, l'eau de fleur d'oranger, which is frequently taken by ladies as a gentle sedative at night, when sufficiently diluted with sugared water. Thousands of gallons are drunk in this way every year. As a pleasant and safely effective help towards wooing sleep, from one to two teaspoonfuls of the French Eau de fleur d'oranger, if taken at bedtime in a teacupful of hot water, are to be highly commended for a nervous, or excitably wakeful person.

Orange buds are picked green from the trees in the gardens of the Riviera, and when dried they retain the sweet smell of the flowers. A teaspoonful of these buds is ordered to be infused in a teacupful of quite hot water, and the liquid to be drunk shortly, before going to bed. The effect is to induce a refreshing sleep, without any subsequent headache or nausea. The dried berries may be had from an English druggist.

A peeled Orange contains, some citric acid, with citrate of potash; also albumen, cellulose, water, and about eight per cent. of sugar. The white lining pith of the peel possesses likewise the crystalline principle "hesperidin." Dr. Cullen showed that the acid juice of oranges, by uniting with the bile, diminishes the bitterness of that secretion; and hence it is that this fruit is of particular service in illnesses which arise from a redundancy of bile, chiefly in dark persons of a fibrous, or bilious temperament. But if the acids of the Orange are greater in quantity than can be properly corrected by the bile (as in persons with a small liver, and feeble digestive powers), they seem, by some prejudicial union with that liquid, to acquire a purgative quality, and to provoke diarrhoea, with colicky pains.

The rind or peel of the Seville Orange is darker in colour, and more bitter of taste than that of the sweet China fruit. It affords a considerable quantity of fragrant, aromatic oil, which partakes of the characters exercised by the leaves and the flowers as affecting the nervous system. Pereira records the death of a child which resulted from eating the rind of a sweet China Orange.

The small green fruits (windfalls) from the Orange trees of each sort, which become blown off, or shaken down during the heats of the summer, are collected and dried, forming the "orange berries" of the shops. They are used for flavouring curacoa, and for making issue peas. These berries furnish a fragrant oil, the essence de petit grain, and contain citrates, and malates of lime and potash, with "hesperidin," sulphur, and mineral salts. The Orange flowers yield a volatile, odorous oil, acetic acid, and acetate of lime. The juice of the Orange consists of citric and malic acids, with sugar; citrate of lime, and water. The peel furnishes hesperidin, a volatile oil, gallic acid, and a bitter principle.

By druggists, a confection of bitter orange peel is sold; also a syrup of this orange peel, and a tincture of the same, made with spirit of wine, to be given in doses of from one to two teaspoonfuls with water, as an agreeable stomachic bitter. Eau de Cologne contains oil of neroli, oil of citron, and oil of orange.

The fresh juice of Oranges is antiseptic, and will prevent scurvy if taken in moderation daily. Common Oranges cut through the middle while green, and dried in the air, being afterwards steeped for forty days in oil, are used by the Arabs for preparing an essence famous among their old women because it will restore a fresh dark, or black colour to grey hair. The custom of a bride wearing Orange blossoms, is probably due to the fact that flowers and fruit appear together on the tree, in token of a wish that the bride may retain the graces of maidenhood amid the cares of married life. This custom has been derived from the Saracens, and was originally suggested also by the fertility of the Orange tree.

The rind of the Seville Orange has proved curative of ague, and powerfully remedial to restrain the monthly flux of women when in excess. Its infusion is of service also against flatulency. A drachm of the powdered leaves may be given for a dose in nervous and hysterical ailments. Finally, "the Orange," adds John Evelyn, "sharpens appetite, exceedingly refreshes, and resists putrefaction."

With respect to the fruit, it is said that workpeople engaged in the orange trade enjoy a special immunity from influenza, whilst a free partaking of the juice given largely, has been found preventive of pneumonia as complicating this epidemic. The benefit is said to occur through lessening the fibrin of the blood.

In the time of Shakespeare, it was the fashion to carry "pomanders," these being oranges from which all the pulp had been scooped out, whilst a circular hole was made at the top. Then after the peel had become dry, the fruit was filled with spices, so as to make a sort of scent-box. Orange lilies, Orangemen, and William of Orange, are all more or less associated with this fruit. The Dutch Government had no love for the House of Orange: and many a grave burgomaster went so far as to banish from his garden the Orange lily, and Marigold; also the sale of Oranges and Carrots was prohibited in the markets on account of their aristocratic colour.

There exists at Brighton a curious custom of bowling or throwing Oranges along the high road on Boxing day. He whose Orange is hit by that of another, forfeits the fruit to the successful hitter.

In Henry the Eighth's reign Oranges were made into pies, or the juice was squeezed out, and mixed with wine. This fruit when peeled, and torn into sections, after removing the white pith, and the pips, and sprinkling over it two or three spoonfuls of powdered loaf sugar, makes a most wholesome salad. A few candied orange-flower petals will impart a fine flavour to tea when infused with it.
