FAMILY N.O. Labiatae SPECIES Rosmarinus officinalis DESCRIPTION The evergreen leaves of this shrubby herb are about 1 inch long, linear, revolute, dark green above and paler and glandular beneath, with an odour pungently aromatic and somewhat camphoraceous. The flowers are small and pale blue. Much of the active volatile principle resides in their calyces. There are silver and goldstriped varieties, but the green-leaved variety is the kind used medicinally. PARTS USED The oil of Rosemary, distilled from the flowering tops, as directedin the British Pharmacopceia, is a superior oil to that obtained from the stem and leaves, but nearly all the commercial oil is distilled from the stem and leaves of the wild plant before it is in flower. The upper portions of the shoots are taken, with the leaves on and the leaves are stripped off the portions of the shoots that are very wooden.

CULTIVATION
Rosemary is propagated by seeds, cuttings and layers, and division of roots. (1) Seeds may be sown upon a warm, sunny border. (2) Cuttings, taken in August, 6 inches long, and dibbled into a shady border, two-thirds of their length in the ground, under a hand-glass, will root and be ready for transplanting into permanent quarters the following autumn. (3) Layering may be readily accomplished in summer by pegging some of the lower branches under a little sandy soil.

Rosemary succeeds best in a light, rather dry soil, and in a sheltered situation, such as the base of a low wall with a south aspect. On a chalk soil it grows smaller, but is more fragrant. The silver- and gold-striped kinds are not quite so hardy.

CONSTITUENTS The plant contains some tannic acid, together with a resin and a bitter principle and a volatile oil. The chief constituents of the oil are Borneol, bornyl acetate and other esters, a special camphor similar to that possessed by the myrtle, cineol, pinene and camphene. It is colourless, with the odour of Rosemary and a warm camphoraceous taste. The chief adulterants of oil of Rosemary are oil of turpentine and petroleum. Rosemary yields its virtues partly to water and entirely to rectified spirits of wine. From 100 lb. of the flowering tops, 8 OZ. of the oil are usually obtained.

USES
Tonic, astringent, diaphoretic, stimulant. Oil of Rosemary has the carminative properties of other volatile oils and is an excellent stomachic and nervine, curing many cases of headache.

It is employed principally, externally, as spiritus Rosmarini, in hair-lotions, for its odour and effect in stimulating the hair-bulbs to renewed activity and preventing premature baldness. An infusion of the dried plant (both leaves and flowers) combined with borax and used when cold, makes one of the best hairwashes known. It forms an effectual remedy for the prevention of scurf and dandruff.

The oil is also used externally as a rubefacient and is added to liniments as a fragrant stimulant. Hungary water, for outward application to renovate the vitality of paralysed limbs, was first invented for a Queen of Hungary, who was said to have been completely cured by its continued use. It was prepared by putting 1 1/2 lb. of fresh Rosemary tops in full flower into 1 gallon of spirits of wine, this was allowed to stand for four days and then distilled. Hungary water was also considered very efficacious against gout in the hands and feet, being rubbed into them vigorously.

Rosemary Wine when taken in small quantities acts as a quieting cordial to a weak heart subject to palpitation, and relieves accompanying dropsy by stimulating the kidneys. It is made by chopping up sprigs of green Rosemary and pouring on them white wine, which is strained off after a few days and is then ready for use. By stimulating the brain and nervous system, it is a good remedy for headaches caused by feeble circulation.

The young tops, leaves and flowers can be made into an infusion, called Rosemary Tea, which, taken warm, is a good remedy for removing headache, colic, colds and nervous diseases, care being taken to prevent the escape of steam during its preparation. It will relieve nervous depression. A conserve, made by beating up the freshly gathered tops with three times their weight of sugar, is said to have the same effect.

A spirit of Rosemary may be used, in doses of 30 drops in water or on sugar, as an antispasmodic.

Rosemary and Coltsfoot leaves are considered good when rubbed together and smoked for asthma and other affections of the throat and lungs.

Rosemary is also one of the ingredients used in the preparation of Eau-de-Cologne.
