The Root of Cochlearia Armoracia. Horse-radish Plant. Nat. Ord. CuciferAe. Linn. Syst. Tetradynamia Siliculosa. Hab. England and N. Europe.

Med. Prop. and Action. Stimulant sudorific and diuretic, in doses of fl. oz. j. - fl. oz. ij. of the Infusion (Ph. Lond.; (Rad. Arm. j., Sinapis j., Sp. Arm. Comp. fj., Aq. Ferv. Oj.), or of fl. drrn. j. - fl. drs. iij. of the compound spirit. When chewed, it causes a great flow of saliva; hence it is used as a masticatory. Taken internally, it causes a sensation of warmth, expels flatus, promotes digestion, and increases the appetite; if given infused in hot water, it readily proves emetic, and may be employed by itself, to promote vomiting, or to assist the operation of other emetics. It is also stimulant to the nervous system, and, in large quantities, proves heating to the whole body, and increases the secretions, particularly the urine and the perspiration. (Cullen.) Externally applied, it is irritant and vesicant. Its virtues depend upon a volatile oil (C8H5NS2) identical with oil of mustard. In India, a perfect substitute is found in the root of Hyperanthera Moringa (Suhunjuna, Hind.), or Horse-radish Tree.

Offic. Prep. Spiritus ArmoraciAe Compositus (Horse-radish sliced oz. xx.; Bitter Orange Peel dried oz. xx.; Nutmeg bruised oz. as.; Proof Sp. Cj., Water Oij. Mix. Distil. Cj.). Dose, fl. drm. j. - iij.

Incompatibles. Alkalies and their Carbonates; the salts of Silver and Mercury.

3S2. Therapeutic Uses. In Dropsical Affections occurring after Fevers, and attended with much debility, Sydenham successfully employed the Infusion of Horse-radish; and, from its stimulant and diuretic properties, it is doubtless a valuable medicine in these cases. M. Rayer observes that, of all diuretics, it is the one which appears to him to offer the best chances of success.

383. In Rheumatic and Arthritic Diseases, Horse-radish is very favourably spoken of by Cullen. Bergius advises that it should be cut into small pieces, and swallowed without chewing to the extent of a tablespoonful daily. Thus taken, none of the volatile parts of the root are lost. It may at the same time be applied externally in the form of poultice or embrocation.

384. In Scurvy It Has Long Been Esteemed As A Remedy

385. In Paralysis, the scraped root, made into a poultice, has been found very useful as a rubefacient. If allowed to remain on too long, it will cause vesication. The infusion (ut supra) may also be advantageously given internally.

386. In Hoarseness arising from Relaxation, the concentrated infusion, made into a syrup and used as a gargle, is recommended by Cullen. In Toothache, Horse-radish, if chewed slowly, affords occasional relief, by stimulating the salivary glands.
