CLOVES , the dried, unexpanded See also:flower-buds of Eugenia caryophyllata, a See also:tree belonging to the natural See also:order Myrtaceae . They are so named from the See also:French word clou, on See also:account of their resemblance to a See also:nail . The clove tree is a beautiful See also:evergreen which grows to a height of from 30 to 40 ft., having large See also:oval leaves and See also:crimson See also:flowers in numerous See also:groups of terminal clusters . The flower-buds are at first of a See also:pale See also:colour and gradually become See also:green, after which they develop into a See also:bright red, when they are ready for See also:collecting . Cloves are rather more than See also:half an See also:inch in length, and consist of a See also:long cylindrical°calyx, terminating in four spreading sepals, and four unopened petals which See also:form a small See also:ball in the centre . The tree is a native of the small See also:group of islands in the See also:Indian See also:Archipelago called the See also:Moluccas, or Spice Islands; but it was long cultivated by the Dutch in See also:Amboyna and two or three small neighbouring islands . Cloves were one of the See also:principal See also:Oriental spices that See also:early excited the cupidity of Western commercial communities, having been the basis of a See also:rich and lucrative See also:trade from an early See also:part of the See also:Christian era . The Portuguese, by doubling the Cape of See also:Good See also:Hope, obtained See also:possession of the principal portion of the clove trade, which they continued to hold for nearly a See also:century, when, in 16o5, they were expelled from the Moluccas by the Dutch . That See also:power exerted See also:great and inhuman efforts to obtain a See also:complete See also:monopoly of the trade, attempting to extirpate all the clove trees growing in their native islands, and to concentrate the whole See also:production in the Amboyna Islands . With great difficulty the French succeeded in introducing the clove tree into See also:Mauritius in the See also:year 1770; subsequently the cultivation was introduced into See also:Guiana, See also:Brazil, most of the See also:West Indian Islands and See also:Zanzibar . The See also:chief commercial See also:sources of See also:supply are now Zanzibar and its neighbouring See also:island See also:Pemba on the See also:East See also:African See also:coast, and Amboyna . Cloves are also grown in See also:Java, See also:Sumatra, See also:Reunion, Guiana and the West See also:India Islands .
Cloves as they come into the See also:market have a deep See also: The British Pharmacopoeia contains an infusion of cloves (Infusum Caryophylli), of which the strength is 1. part in 40 of boiling water and the dose z-1 oz . Cloves are employed principally as a condiment in culinary operations, in See also:confectionery, and in the preparation of See also:liqueurs . In See also:medicine they are tonic and carminative, but they are little used except as adjuncts to other substances on account of their flavour, or with purgatives to prevent See also:nausea and griping . The essential oil forms a convenient See also:medium for using cloves for flavouring purposes, it possesses the medicinal properties characteristic of a volatile oil, and it is frequently employed to relieve toothache . Oil of cloves is regarded by many dental surgeons as the most effective See also:local anaesthetic they possess in cases where it is desired, before cutting a sensitive tooth for the purpose of filling it, to See also:lower the sensibility of the dentine . For this purpose the cavity must be exposed to See also:cotton See also:wool saturated with the oil for about ten days . |
