DISTRIBUTION Native to Japan and Taiwan principally, also China; cultivated in India, Ceylon, Egypt, Madagascar, southern Europe and America.
OTHER SPECIES There are many species of camphor: the ho-sho variety produces ho leaf and ho wood oil; the Chinese variety produces apopin oil; the Japan and Taiwan type, known as hon-sho or true camphor, produces two chemotypes: camphor-safrol (Japan) and camphor-linalol (Taiwan). All these are to be distinguished from the Borneo camphor or borneol which is of different botanical origin.
HERBAL/FOLK TRADITION A long-standing traditional preventative of infectious disease; a lump of camphor would be worn around the neck as a protection. In addition it was used for nervous and respiratory diseases in general, and for heart failure! However, in its crude form it is very poisonous in large doses, and has been removed from the British Pharmacopoeia.
ACTIONS Anti-inflammatory, antiseptic, antiviral, bactericidal, counter-irritant, diuretic, expectorant, stimulant, rubefacient, vermifuge.
EXTRACTION Crude camphor is collected from the trees in crystalline form. The essential
oil is produced by steam distillation from the wood, root stumps and branches and then rectified under vacuum and filter pressed to produce three fractions, known as white, brown and yellow camphor.
CHARACTERISTICS White camphor is the lightest (lowest boiling) fraction, a colourless to pale yellow liquid with a sharp, pungent camphoraceous odour. Brown camphor is the middle fraction. Yellow camphor, a blue-green or yellowish liquid, is the heaviest.
PRINCIPAL CONSTITUENTS 1 White camphor contains mainly cineol, with pinene, terpineol, menthol, thymol and no safrol. 2. Brown camphor contains up to 80 per cent safrol and some terpineol. 3. Yellow camphor contains mainly safrol, sesquiterpenes and sesquiterpene alcohols.
SAFETY DATA Brown and yellow camphor (containing safrol) are toxic and carcinogenic and ‘should not be used in therapy, either internally or externally.’

White camphor does not contain safrol and is relatively non-toxic, non-sensitizing and non-irritant. It is, however, an enviromental hazard or marine pollutant.
AROMATHERAPY/HOME USE White camphor may be used with care for:
SKIN CARE
: Acne, inflammation, oily conditions, spots; also for insect prevention (flies, moths, etc).
CIRCULATION, MUSCLES AND JOINTS
: Arthritis, muscular aches and pains, rheumatism, sprains, etc.
RESPIRATORY SYSTEM
: Bronchitis, chills, coughs.
IMMUNE SYSTEM
: Colds, fever, ’flu, infectious disease.
OTHER USES White and brown camphor are used as the starting material for the isolation of many perfumery chemicals, for example safrol and cineol. White camphor is used as a solvent in the paint and lacquer industry, and for the production of celluloid. Fractions of white oil are used as fragrance and masking agents in detergents, soaps, disinfectants and household products.
Cananga odorata
FAMILY Annonaceae
SYNONYM C.
odoratum var. macrophylla.
GENERAL DESCRIPTION A tall tropical tree, up to 30 metres high, which flowers all year round. It bears large, fragrant, tender yellow flowers which are virtually identical to those of the ylang ylang.
DISTRIBUTION Native to tropical Asia: Java, Malaysia, the Philippines, the Moluccas.
OTHER SPECIES Very closely related to the tree which produces ylang ylang oil, C.
odorata var. genuina.
Cananga is considered an inferior product in perfumery work; being grown in different regions the oil has a different quality, heavier and less delicate than ylang ylang. However, cananga is truly a ‘complete’ oil whereas ylang ylang is made into several distillates.
HERBAL/FOLK TRADITION Used locally for infectious illnesses, for example malaria. The beautiful flowers are also used for decorative purposes at festivals.
