"Whoso taketh," says Parkinson, "but one scruple of _Gratiola_ (Hedge Hyssop) bruised, shall perceive evidently his effectual operation and virtue in purging mightily, and that in great abundance, watery, gross, and slimy tumours." _Caveat qui sumpserit_. On the principle of affinities, small diluted doses of the tincture, or decoction, or of the dried leaves, prove curative in cases of fluxes from the lower bowels, where irritation within the fundament is frequent, and where there is considerable nervous exhaustion, especially in chronic cases of this sort. IVY, Common (_Araliaceoe_). The clergyman of fiction in the sixth chapter of Dickens' memorable _Pickwick_, sings certain verses which he styles "indifferent" (the only verse, by the way, to be found in all that great writer's stories), and which relate to the Ivy, beginning thus:-- "Oh! a dainty plant is the Ivy green, That creepeth o'er ruins old." The well known common Ivy (_Hedera helix_), which clothes the trunks of trees and the walls of old buildings so picturesquely throughout Great Britain, gets its botanical name most probably from the Celtic word _hoedra _[281] "a cord," or from the Greek _hedra_ "a seat," because sitting close, and its vernacular title from _iw_ "green," which is also the parent of "yew." In Latin it is termed _abiga_, easily corrupted to "iva"; and the Danes knew it as Winter-grunt, or Winter-green, to which appellation it may still lay a rightful claim, being so conspicuously green at the coldest times of the year when trees are of themselves bare and brown. By the ancients the Ivy was dedicated to Bacchus, whose statues were crowned with a wreath of the plant, under the name Kissos, and whose worshippers decorated themselves with its garlands. The leaves have a peculiar faintly nauseous odour, whilst they are somewhat bitter, and rough of taste. The fresh berries are rather acid, and become bitter when dried. They are much eaten by our woodland birds in the spring. A crown of Ivy was likewise given to the classic poets of distinction, and the Greek priests presented a wreath of the same to newly married persons. The custom of decorating houses and churches with Ivy at Christmastide, was forbidden by one of the early councils on account of its Pagan associations. Prynne wrote with reference to this decree:-- "At Christmas men do always Ivy get, And in each corner of the house it set, But why make use then of that Bacchus weed? Because they purpose Bacchus-like to feed." The Ivy, though sending out innumerable small rootlets, like suckers, in every direction (which are really for support) is not a parasite. The plant is rooted in the soil and gets its sustenance therefrom. Chemically, its medicinal principles depend on the special balsamic resin contained in the leaves and stems, as well as constituting the aromatic gum. [282] Ivy flowers have little or no scent, but their yield of nectar is particularly abundant.
