FAMILY: Cupressaceae
SYNONYMS: J. mexicana, mountain cedar, Mexican cedar, rock cedar, Mexican juniper.
GENERAL DESCRIPTION: A small, alpine evergreen tree up to 7 metres high with stiff green needles and an irregular shaped trunk and branches, which tend to be crooked or twisted, The wood also tends to crack easily, so it is not used for timber.
DISTRIBUTION: Native to south western USA, Mexico and Central America; the oil is produced mainly in Texas.
OTHER SPECIES: The name J. mexicana has erroneously been applied to many species; botanically related to the so-called Virginian cedarwood (J. virginiana) and the East African cedarwood (J. procera).
HERBAL/FOLK TRADITION: In New Mexico the native Indians use cedarwood oil for skin rashes. It is also used for arthritis and rheumatism.
ACTIONS: Antiseptic, antispasmodic, astringent, diuretic, expectorant, sedative (nervous), stimulant (circulatory).
EXTRACTION: Essential oil by steam distillation from the heartwood and wood shavings, etc. (Unlike the Virginian cedar, the tree is felled especially for its essential oil.)
CHARACTERISTICS: Crude – a dark orange to brownish viscous liquid with a smoky-woody, sweet tar-like odour. Rectified – a colourless or pale yellow liquid with a sweet, balsamic, ‘pencil wood’ scent, similar to Virginian cedarwood but harsher. It blends well with patchouli, spruce, vetiver, pine and leather-type scents.
