Infused in wine the root stimulates the whole nervous system, and promotes perspiration, whilst acting likewise as a diuretic. For rheumatic neuralgia [272] it is almost a specific, and for palsy it has often proved of service. Our druggists prepare a "compound spirit of Horse radish," made with the sliced fresh root, orange peel, nutmeg, and spirit of wine. This proves of effective use in strengthless, languid indigestion, as well as for chronic rheumatism; it stimulates the stomach, and promotes the digestive secretions. From one to two teaspoonfuls may be taken two or three times in the day, with half a wineglassful of water, at the end of a principal meal, or a few minutes after the meal. An infusion of the root made with boiling water and taken hot readily proves a stimulating emetic. Until cut or bruised the root is inodorous; but fermentation then begins, and develops from the essential oil an ammoniacal odour and a pungent hot bitter taste which were not pre-existing. Chemically the Horse radish contains a volatile oil, identical with that of mustard, being highly diffusible and pungent by reason of its "myrosin." One drop of this volatile oil will suffice to odorise the atmosphere of a whole room, and, if swallowed with any freedom, it excites vomiting. Other constituents of the root are a bitter resin, sugar, starch, gum, albumen, and acetates. A mixture of the fresh juice, with vinegar, if applied externally, will prove generally of service for removing freckles. Bergius alleges that by cutting the root into very small pieces without bruising it, and then swallowing a tablespoonful of these fragments every morning without chewing them, for a month, a cure has been effected in chronic rheumatism, which had seemed otherwise intractable. For loss of the voice and relaxed sore throat the [273] infusion of Horse radish makes an excellent gargle; or it may be concentrated in the form of a syrup, and mixed for the same use--a teaspoonful, with a wine-glassful of cold water. Gerard said of the root: "If bruised and laid to the part grieved with the sciatica, gout, joyntache, or the hard swellings of the spleen and liver, it doth wonderfully help them all." If the scraped root be macerated in vinegar, it will form a mixture (which may be sweetened with glycerine to the taste) very effective against whooping cough. In pimply acne of the skin, to touch each papula with some of the Compound Spirit of Horse Radish now and again will soon effect a general cure of the ailment. HOUSE LEEK (Crassulaceoe).
