In Italy stables are popularly thought to be protected by a sprig of Juniper from demons and thunderbolts, just as we suppose the magic horseshoe to be protective to our houses and offices.
[296] KNAPWEED (The Lesser).
Black Knapweed, the Centaurea nigra, is a common tough-stemmed composite weed growing in our meadows and cornfields, being well known by its heads of dull purple flowers, with brown, or almost black scales of the outer floral encasement. It is popularly called Hard heads, Loggerheads, Iron heads, Horse knob, and Bull weed.
Dr. Withering relates that a decoction made from these hard heads has afforded at least a temporary relief in cases of diabetes mellitus, "by diminishing the quantity of urine, and dispelling the sweetness."
Its chief chemical constituent enicin, is identical with that of the Blessed thistle, and the Blue bottle, and closely resembles that of the Dandelion. It has been found useful in strengthless indigestion, especially when this is complicated with sluggish torpor of the liver. From half to one ounce of the herb may be boiled in eight fluid ounces of water, and a small wineglassful be taken for a dose twice or three times a day. In Bucks young women make use of this Knapweed for love divination:—
"They pull the little blossom threads
From out the Knotweed's button beads,
And put the husk with many a smile
In their white bosoms for a while;
Then, if they guess aright, the swain
Their love's sweet fancies try to gain,
'Tis said that ere it lies an hour
'Twill blossom with a second flower."
LAVENDER.
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.
By the Greeks the name Nardus is given to Lavender, from Naarda, a city of Syria, near the Euphrates; and many persons call the plant "Nard." St. Mark mentions this as Spikenard, a thing of great value The woman who came to Christ having an alabaster box of ointment of Spikenard, very precious "brake the box, and poured it on His head." In Pliny's time blossoms of the nardus sold for a hundred Roman denarii (or £3 2s. 6d.) the pound. This Lavender or Nardus, was likewise called Asarum by the Romans, because not used in garlands or chaplets. It was formerly believed that the asp, a dangerous kind of viper, made Lavender its habitual place of abode, so that the plant had to be approached with great caution.
Conserves of Lavender were much used in the time of Gerard, and desserts may be most pleasantly brought to the table on a service of Lavender spikes. It is said, on good authority, that the lions and tigers in our Zoological gardens, are powerfully affected by the smell of Lavender-water and become docile under its influence.
