Rustics corrupt the double title to "Liry Confancy," and provincially the plant is known as "Wood Lily," "May Lily," and "May Blossom." Also it bears the name of Mugget, and is said to have grown up after the bloody combat of St. Leonard with the Dragon. The French call it _Muguet_, or "little musk." The taste of the flowers is acrid and bitter; they have been [314] employed with benefit, when dried and powdered, as snuff, for headache, and giddiness arising from weakness. A tincture of the plant is made, and can be procured from any leading druggist. The active medicinal principle is "convallarin," which slows the disturbed action of a weak, irritable heart, whilst at the same time increasing its power. Happily the remedy is a perfectly safe one, and no harm has been known to occur from taking it experimentally in full and frequent doses; so that, in this respect, it is far preferable to the Fox Glove, which is apt to accumulate in the blood with poisonous results. To make the tincture of _Convallaria_, one part of the flowers is treated with eight parts of spirit of wine (proof); and the dose is from five to fifteen drops, with a tablespoonful of water, three times in the twenty-four hours. Also an infusion may be made with boiling water poured over the whole plant-root, stems, and flowers; and this infusion may be given continuously for from five to ten days; but it should be left off for a time as soon as the irritability of the heart is subdued, and the pulse steady and stronger. If taken during an attack of palpitation and laboured breathing from a weak heart, the benefit of the infusion in tablespoonful doses is felt at once. Ten grains of the dried flowers may be infused in six ounces of boiling water; and a tablespoonful of this be given three times a day with perfect safety, and with a most soothing effect for a weak, sensitive, palpitating heart; but it does not suit a fatty heart equally well. Nevertheless, even for insufficiency of the valves, when dangerous, or distressing symptoms of heart disease have set in, an infusion of the flowers has proved very helpful. The _rhizome_, root, exhales a pleasant odour, [315] different from that of the flowers; it tastes sweet at first but afterwards bitter. A fluid extract is further prepared, and may be mixed in doses of from five to twenty drops with water. The Russian peasants have long employed the Lily of the Valley for certain forms of dropsy, when proceeding from a faulty heart.
