The Lavender of our gardens, called also Lavender Spike, is a well-known sweet-smelling shrub, of the Labiate order. It grows wild in Spain, Piedmont, and [297] the south of France, on waysides, mountains, and in barren places. The plant was propagated by slips, or cuttings, and has been cultivated in England since about 1568. It is produced largely for commercial purposes in Surrey, Hertfordshire, and Lincoln. The shrub is set in long rows occupying fields, and yields a profitable fragrant essential oil from the flowering tops, about one ounce of the oil from sixty terminal flowering spikes. From these tops also the popular cosmetic lavender water is distilled. They contain tannin, and a resinous camphire, which is common to most of the mints affording essential oils. If a hank of cotton is steeped in the oil of Lavender, and drained off so as to be hung dry about the neck, it will prevent bugs and other noxious insects from attacking that part. When mixed with three-fourths of spirit of turpentine, or spirit of wine, this oil makes the famous _Oleum spicoe_, formerly much celebrated for curing old sprains and stiff joints. Lavender oil is likewise of service when rubbed in externally, for stimulating paralysed limbs--preferring the sort distilled from the flowering tops to that which is obtained from the stalks. Internally, the essential oil, or a spirit of Lavender made therefrom, proves admirably restorative and tonic against faintness, palpitations of a nervous sort, weak giddiness, spasms, and colic. It is agreeable to the taste and smell, provokes appetite, raises the spirits, and dispels flatulence; but the infusion of Lavender tops, if taken too freely, will cause griping, and colic. In hysteria, palsy, and similar disorders of debility, and lack of nerve power, the spirit of Lavender will act as a powerful stimulant; and fomentations with Lavender in bags, applied hot, will speedily relieve local pains. "It profiteth them much," says Gerard, "that have the palsy if they be washed with the distilled water [298] from the Lavender flowers; or are anointed with the oil made from the flowers and olive oil, in such manner as oil of roses is used." A dose of the oil is from one to four drops on sugar, or on a small piece of bread crumb, or in a spoonful or two of milk. And of the spirit, from half to one teaspoonful may be taken with two tablespoonfuls of water, hot or cold, or of milk. The spirit of Lavender is made with one part of the essential oil to forty-nine parts of spirit of wine. For preparing distilled Lavender water, the addition of a small quantity of musk does much to develop the strength of the Lavender's odour and fragrance. The essential oil of _Lavandula latifolia_, admirably promotes the growth of the hair when weakly, or falling off.
