Not a few fatal cases have occurred of persons being poisoned by taking Aconite root in mistake for a stick of Horse radish, and eating it when scraped. But the two roots differ materially in shape, colour, and taste, so as to be easily discriminated: furthermore the leaves of the Aconite--supposing them to be attached to the root--are not to be mistaken for those of any other plant, being completely divided to their base into five wedge-shaped lobes, which are again sub-divided into three. Squire says it seems incredible that the Aconite Root should be mistaken for Horse Radish unless we remember that country folk are in the habit of putting back again into the ground Horse Radish which has been scraped, until there remain only the crown and a remnant of the root vanishing to a point, these bearing resemblance to the tap root of Aconite. The fresh root of the Horse radish is a powerful stimulant by reason of its ardent and pungent volatile principle, whether it be taken as a medicament, or be applied externally to any part of the body. When scraped it exhales a nose-provoking odour, and possesses [271] a hot biting taste, combined with a certain sweetness: but on exposure to the air it quickly turns colour, and loses its volatile strength; likewise, it becomes vapid, and inert by being boiled. The root is expectorant, antiscorbutic, and, if taken at all freely, emetic. It contains a somewhat large proportion of sulphur, as shown by the black colour assumed by metals with which it comes into touch. Hence it promises to be of signal use for relieving chronic rheumatism, and for remedying scurvy. Taken in sauce with oily fish or rich fatty viands, scraped Horse radish acts as a corrective spur to complete digestion, and at the same time it will benefit a relaxed sore throat, by contact during the swallowing. In facial neuralgia scraped Horse radish applied as a poultice, proves usefully beneficial: and for the same purpose some of the fresh scrapings may be profitably held in the hand of the affected side, which hand will become in a short time bloodlessly benumbed, and white. When sliced across with a knife the root of the Horse radish will exude some drops of a sweet juice which may be rubbed with advantage on rheumatic, or palsied limbs. Also an infusion of the sliced root in milk, almost boiling, and allowed to cool, makes an excellent and safe cosmetic; or the root may be infused for a longer time in cold milk, if preferred, for use with a like purpose in view. Towards the end of the last century Horse radish was known in England as Red cole, and in the previous century it was eaten habitually at table, sliced, with vinegar.
