Camphor is a white transparent waxy crystalline solid with a strong penetrating pungent aromatic odor. It is found in wood of the camphor laurel, Cinnamomum camphora, which is a large evergreen tree found in Asia (particularly in Borneo, hence its alternate name); it can also be synthetically produced from oil of turpentine.
Modern uses include as a plasticizer for cellulose nitrate, as a moth repellent, in embalming, and in fireworks. A form of anti-itch gel currently on the market uses camphor as its active ingredient. Historically it has been used in medicine. In 1980, the United States Food and Drug Administration set a limit of 11% allowable camphor in consumer products and totally banned products labeled as camphorated oil, camphor oil, camphor liniment, and camphorated liniment. Camphor is readily absorbed through the skin and produces a feeling of cooling similar to that of menthol and acts as slight local anesthetic; however, it is poisonous and can cause seizures, mental confusion, irritability, and neuromuscular hyperactivity. Since alternative treatments exist, medicinal use of camphor is discouraged, except for dermatic(skin-related) uses in small amounts.
Other products derived from trees are sometimes sold, wrongly, as camphor.
