Camphor is derived from the heartwood of the camphor laurel, Cinnamomum camphor a (Lauraceae), in the (+) isomeric form. The (-) form occurs in feverfew, Tanacetum parthenium (Asteraceae), and in some lavender varieties. It is regarded as an undesirable constituent in lavender oil. Much of the camphor used in commerce is prepared synthetically from other monoterpenes. Camphor is a CNS stimulant, primarily used as a topical agent for its antipruritic, rubifacient and mucolytic properties. It is toxic in high doses. 

Camphor is naturally occurring in the camphor laurel tree Cinnamomum camphora), but it can be obtained synthetically from turpentine oil. It possesses a cyclic turpentine structure, so it is very lipophilic, which is the reason why it is so well distributed in the body and can make crossings through mucus membranes and probably attract myelinated axons. Camphor is used in medicine for its local anesthetic, antipruritic, and antiseptic activities and as a expectorant in pharmaceutical preparations [137]. Camphor has been cherished for its medical uses for ages in Asia it remains less known in other parts of the world. Camphor vapor is not irritating to the eyes, so it is used in cosmeticproducts and also in room fresheners or in food as a disinfectant [138].

Bicyclic ketone camphor, formed by oxidation of borneol, is a component of cinnamon, sage and rosemary essential oils. In nature, camphor is formed by the oxidation of borneol, and usually occurs as a mixture of two isomers, (+)-camphor (8-51), which is more common, and (-)-camphor (8-51). Camphor is obtained from the camphor laurel tree wood Camphor officinalis, syn. Cinnamomum camphora, Lauraceae) originating in Indochina, where it grows in large numbers. A further sesquiterpenic ketone is (-)-fenchone (8-51), which is found in many essential oils, for example in fennel essential oil. 

The molecule carvone (14.3) is interesting because the two enantiomers have different plant origins and very different tastes. i -Carvone is the main taste constituent of spearmint oil, but S-carvone is obtained from caraway seed oil. Camphor (14.4) comes from the wood of the camphor laurel and is widely used in Asia in cooking and religious ceremonies.

Cinnamon is the inner bark of a small evergreen tree, Cinnomomum zeylan-icum or C. verum, which is in the laurel family. Cassia (C. aromaticum) and camphor (C. camphora) are other members of this genus. The bark, leaves, and sometimes whole stems from these trees are also used as a spice. Cassia is sometimes called bastard cinnamon because it is produced in greater quantities, but is less aromatic than true cinnamon. All of these spices have been combined with resin and vegetable soils to produce fragrant oils and incense. Cinnamon and other similar fragrant bark powders have been used medicinally to treat many ailments, from kidney disease to snakebite.

At around the same time in the United States, a bilfiard ball company advertised a 10,000 reward for the discovery of an alternate material to ivory. John Wesley Hyatt developed collodion, a mixture of cellulose nitrate and alcohol. Like cellulose nitrate, collodion was highly flammable and would produce a small explosion upon agitation. Hyatt reported [W]e had a letter from a billiard saloon proprietor in Colorado mentioning this fact. . . saying he did not care so much about it, but that instantly every man in the room pulled a gun. To avoid melee, camphor, a derivative of the laurel tree, was added, and in 1870 Hyatt received a U.S. patent for celluloid. In 1871 Hyatt and his brother Isaiah formed the American Celluloid Company, which is today the Plastics Division of the Celanese Corporation. 

Laurel Oil, Laurel berry oil. Fixed oil from fresh fruit of Lauras nobilis L., Lauraceae. Constit. Chiefly the lauryl alcohol esters of lauric, stearic, etc., acids and a volatile oil, the so-called laurel camphor. 

It forms small, white, transparent, friable crystals has an odor which recalls at the same time those of laurel camphor and of pepper has a hot taste is insoluble in water, readily soluble in alcohol, ether and [acetic acid fuses at IGS" (388°.4 P.), boils at 312 (413 .6P.). 

It is a true alcohol, and enters into double decomposition with acids to form ethers. When heated with PaOi, it yields a hydrocarbon, bomeene, CioHie. Oxidized by HNOs, it is converted into laurel camphor.
