The herb has a pleasant scent and a bitter, pungent taste, whilst much of its volatile, active principle resides in the calices of the flowers; therefore, in storing or using the plant these parts must be retained. It yields its virtues partially to water, and entirely to rectified spirit of wine.
In early times Rosemary was grown largely in kitchen gardens, and it came to signify the strong influence of the matron who dwelt there:—
"Where Rosemary flourishes the woman rules,"
The leaves and tops afford an essential volatile oil, but not so much as the flowers.
A spirit made from this essential oil with spirit of wine will help to renovate the vitality of paralyzed limbs, if rubbed in with brisk friction. The volatile oil [472] includes a special camphor similar to that possessed by the myrtle. The plant also contains some tannin, with a resin and a bitter principle. By old writers it was said to increase the flow of milk.
The oil is used officinally for making a spirit of Rosemary, and is added to the compound tincture of Lavender, as well as to Soap liniment. By common consent it is agreed that the volatile oil (or the spirit) when mixed in washes will specially stimulate growth of the hair. The famous Hungary water, first concocted for a Queen of Hungary who, by its continual use, became effectually cured of paralysis, was prepared by putting a pound and a half of the fresh tops of Rosemary, when in full flower, into a gallon of proof spirit, which had to stand for four days, and was then distilled.
Hungary water (l'eau de la reine d'Hongrie) was formerly very famous for gout in the hands and feet. Hoyes says, the formula for composing this water, written by Queen Elizabeth's own hand in golden characters, is still preserved in the Imperial Library at Vienna.
An ounce of the dried leaves and flowers treated with a pint of boiling water, and allowed to stand until cold, makes one of the best hair washes known. It has the singular power of preventing the hair from uncurling when exposed to a damp atmosphere. The herb is used in the preparation of Eau de Cologne.
Rosemary wine, taken in small quantities, acts as a quieting cordial to a heart of which the action is excitable or palpitating, and it relieves ally accompanying dropsy by stimulating the kidneys. This wine may be made by chopping up sprigs of Rosemary, and pouring on them some sound white wine, which after two or [473] three days, may be strained off and used. By stimulating the nervous system it proves useful against the headaches of weak circulation and of languid health. "If a garlande of the tree be put around the heade it is a remedy for the stuffing of the head that cometh from coldness."
The green-leaved variety of Rosemary is the sort to be used medicinally. There are also silver and gold-leaved diversities. Sprigs of the herb were formerly stuck into beef whilst roasting as an excellent relish. A writer of 1707 tells of "Rosemary-preserve to dress your beef."
