The camphor tree, Cinnamomum camphora (L.) Siebold [Fam. Lauraceae], is an aromatic tree with all parts of it yielding the odor and giving the taste of it. Camphor trees are native to the eastern and warmer latitudes of Asia. Crude camphor is principally isolated in Canton and then exported to other parts of the world where it undergoes purification for medicinal use. It is an active ingredient in such familiar over-the-counter remedies as Vicks VapoRub and Mentholatum ointment. Rubbed on the skin, camphor stimulates circulation. Its inhaled vapors reduce bronchial secretions. When taken internally, it combats bronchial spasms, improves breathing, and promotes circulation. It is also used as a remedy for vascular disorders, bronchitis, cough, and bone and joint conditions. In Asia, it is also used for acute breathing disorders, indigestion, inflammations and muscle pain. In folk tradition, cakes of it were used as a moth-repellent. It was once popular as a remedy for stomachache and bowel complaints, but fell out of favor due to the danger of overdose, which can easily prove fatal. Many pharmaceutical drugs are prepared from it including a local anaesthetic and antiseptic called carbolated camp. prepared by dissolving 100 parts of camphor and 36 parts of carbolic acid in 4 parts of alcohol or alternatively as 2 parts camphor and 1 part phenol as liquid. Ten-drop doses of an olive-oil solution have been given in catarrh of the stomach and to disinfect wounds, ulcers, boils, and herpetic skin affections, as well as to relieve the pain of ingrown nails and dental caries. Common cinnamon, Cinnamomum zeylanicum, one of the world’s oldest spices, also provides it in the root-bark oil. Approximately twenty-four components are found in the volatile oil isolated from all parts of fresh or dried camphor trees, with camphor as the most abundant component.
