The Juniper shrub (Arkenthos of the ancients), which is widely distributed about the world, grows not uncommonly in England as a stiff evergreen conifer on heathy ground, and bears bluish purple berries. These have a sweet, juicy, and, presently, bitter, brown pulp, containing three seeds, and they do not ripen until the second year. The flowers blossom in May and June. Probably the shrub gets its name from the Celtic _jeneprus_, "rude or rough." Gerard notes that "it grows most commonly very low, like unto our ground furzes." Gum Sandarach, or Pounce, is the product of this tree. Medicinally, the berries and the fragrant tops are employed. They contain "juniperin," sugar, resins, wax, fat, formic and acetic acids, and malates. The fresh tops have a balsamic odour, and a carminative, bitterish taste. The berries afford a yellow aromatic oil, which acts on the kidneys, and gives cordial warmth to the stomach. Forty berries should yield an ounce of the oil. Steeped in alcohol the berries make a capital _ratafia_; they are used in several confections, as well as for flavouring gin, being put into a spirit more common than the true geneva of Holland. The French obtain from these berries the _Genievre_ (_Anglice_ "geneva"), from which we have taken our English word "gin." In France, Savoy, and Italy, the berries are largely collected, and are sometimes eaten as such, fifteen or twenty at a time, to stimulate the kidneys; or they are taken in powder for the same [292] purpose. Being fragrant of smell, they have a warm, sweet, pungent flavour, which becomes bitter on further mastication. Our British _Pharmacopoeia_ orders a spirit of Juniper to be made for producing the like diuretic action in some forms of dropsy, so as to carry off the effused fluid by the kidneys. A teaspoonful of this spirit may be taken, well diluted with water, several times in the day. Of the essential oil the dose is from two to three drops on sugar, or with a tablespoonful of milk. These remedies are of service also in catarrh of the urinary passages; and if applied externally to painful local swellings, whether rheumatic, or neuralgic, the bruised berries afford prompt and lasting relief.
