The Water Figwort, a common English plant which grows by the sides of ditches, and belongs to the scrofula-curing order, has acquired its name because supposed to heal sores in the fundament when applied like figs as a poultice. It further bears the name of Water Betony (page 50), under which title its curative excellence against piles, and for scrofulous glands in the neck has been already described. The whole plant, yielding its juice, may be blended with lard to be used as an ointment; and an infusion of the roots, made with boiling water, an ounce to a pint, may be taken as a medicine—a wineglassful three times in the day.
In Ireland it is known as "Rose noble," also as Kernelwort, because the kernels, or tubers attached to the roots have been thought to resemble scrofulous glands in the neck. "Divers do rashly teach that if it be hanged about the necke, or else carried about one it keepeth a man in health." In France the sobriquet herbe du seige, given to this plant, is said to have been derived from its famous use in healing all sorts of wounds during the long siege of Rochelle under Louis XIII.
[199] The Water Figwort may be readily known by the winged corners of its stems, which, though hollow and succulent, are rigid when dead, and prove very troublesome to anglers. The flowers are much frequented by wasps: and the leaves are employed to correct the taste of senna.
FLAG (Common).
Our English water Flags are true whigs of the old school, and get their generic name because hanging out their banners respectively of dark blue and yellow.
Each is also called Iris, as resembling the rainbow in beauty of colour. The land Flag (Iris versicolor) is well known as growing in swamps and moist meadows, with sword-shaped leaves, and large purple heads of flowers, bearing petals chiefly dark blue, and veined with green, yellow, or white. The water Flag (Iris pseudacorus) is similar of growth, and equally well known by its brilliant heads of yellow flowers, with blade-like leaves, being found in wet places and water courses. The root of the Blue Flag, "Dragon Flower," or "Dagger Flower," contains chemically an "oleo-resin," which is purgative to the liver in material doses, and specially alleviative against bilious sickness when taken of much reduced strength by reason of its acting as a similar. The official dose of this "iridin" is from one to three grains. A liability to the formation of gall stones may be remedied by giving one grain of the oleoresin (iridin) every night for twelve nights.
A medicinal tincture (H.) is made which holds this Iris in solution; and if three or four drops are taken immediately, with a spoonful of water, and the same dose is repeated in half-an-hour if still necessary, an attack of bilious vomiting, with sick headache, and a [200] film before the eyes, will be prevented, or cut short. The remedy is, under such circumstances, a trustworthy substitute for calomel, or blue pill. Orris powder, which is so popular in the nursery, and for the toilet table with ladies, on account of its fresh "violet" scent, is made from the root of this Iris, being named from the genitive ireos.
Louis VII. of France chose this Blue Flag as his heraldic emblem, and hence its name, fleur de lys, has been subsequently borne on the arms of France. The flower was said to have been figured on a shield sent down from heaven to King Louis at Clovis, when fighting against the Saracens. Fleur de Louis has become corrupted to fleur de lys, or fleur de lis.
The Purple Flag was formerly dedicated to the Virgin Mary. A certain knight more devout than learned could never remember more than two words of the Latin prayer addressed to the Holy Mother; these were Ave Maria, which the good old man repeated day and night until he died. Then a plant of the blue Iris sprang up over his grave, displaying on every flower in golden letters these words, Ave Maria. When the monks opened the tomb they found the root of the plant resting on the lips of the holy knight whose body lay buried below.
The Yellow Flag, or Water Flag, is called in the north, "Seggs." Its flowers afford a beautiful yellow dye; and, its seeds, when roasted, can be used instead of coffee. The juice of the root is very acrid when sniffed up the nostrils, and causes a copious flow of water therefrom, thus giving marked relief for obstinate congestive headache of a dull, passive sort. The root is very astringent, and will check diarrhoea by its infusion; also it is of service for making ink. In the [201] south of England the plant is named "Levers." It contains much tannin.
