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; [403] 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 [404] pneumonia as complicating this epidemic. The benefit is said to occur through lessening the fibrin of the blood.
