Eucalyptus Oil - January Featured Essential Oil


Eucalyptus oil is the generic name for distilled oil from the aromatic leaf of Eucalyptus, a genus of the plant family Myrtaceae native to Australia and cultivated worldwide. The leaves of selected Eucalyptus species are steam distilled to extract eucalyptus oil.

The most common eucalyptus species in the world is also known as Nilgiri tree, blue gum tree or fever tree. The tree was orignally native to Australia and is now naturalized in many countries, including Spain, China and Portugal. Its leaves are extremely rich in eucalyptol.

Eucalyptol is used in cough medicines, as well as muscle-warming ointments and liniments. The eucalyptus essential oil contains about 70% eucalyptol, making it an effective remedy for chesty coughs. The oil has a clean, medicinal and penetrating aroma with lovely fresh notes. Eucalyptus oil has a history of wide application, as a pharmaceutical and with antiseptic, repellent, flavouring, fragrance and industrial uses.

General Information on Eucalyptus Oil

Types and production

Eucalyptus oils in the trade are categorized into three broad types according to their composition and main end-use: medicinal, perfumery and industrial. The most prevalent is the standard cineole-based "oil of eucalyptus", a colourless mobile liquid (yellow with age) with a penetrating, camphoraceous, woody-sweet scent. China produces about 75% of the world trade, but most of this is derived from camphor oil fractions rather than being true eucalyptus oil. Significant producers of true eucalyptus oil include South Africa, Portugal, Spain, Brazil, Australia, Chile and Swaziland.

Global production is dominated by Eucalyptus globulus. However, Eucalyptus kochii and Eucalyptus polybractea have the highest cineole content, ranging from 80-95%. The British Pharmacopoeia states that the oil must have a minimum cineole content of 70% if it is pharmaceutical grade. Rectification is used to bring lower grade oils up to the high cineole standard required. Global annual production of eucalyptus oil is estimated at 3,000 tonnes. The eucalyptus genus also produces non-cineole oils, including piperitone, phellandrene, citral, methyl cinnamate and geranyl acetate.

History

Australian Aboriginals use eucalyptus leaf infusions as a traditional medicine for treating body pains, sinus congestion, fever, and colds. Dennis Considen and John White, surgeons on the First Fleet, distilled eucalyptus oil from Eucalyptus piperita found growing on the shores of Port Jackson in 1788 to treat convicts and marines. Baron Ferdinand von Mueller, Victorian botanist, promoted the qualities of Eucalyptus as a disinfectant in "fever districts". Surgeons were using eucalyptus oil as an antiseptic during surgery by the 1880s.

Applications of Eucalyptus Oil

Medicinal and antiseptic
The cineole-based oil is used as component in pharmaceutical preparations to relieve the symptoms of influenza and colds, in products like cough sweets, lozenges, ointments and inhalants. Eucalyptus oil has antibacterial effects on pathogenic bacteria in the respiratory tract. Inhaled eucalyptus oil vapor is a decongestant and treatment for bronchitis. Cineole controls airway mucus hypersecretion and asthma via anti-inflammatory cytokine inhibition. Eucalyptus oil also stimulates immune system response by effects on the phagocytic ability of human monocyte derived macrophages. Eucalyptus oil also has anti-inflammatory and analgesic qualities as a topically applied liniment ingredient. Eucalyptus oil is also used in personal hygiene products for antimicrobial properties in dental care and soaps. It can also be applied to wounds to prevent infection.
Repellent and biopesticide
Cineole-based eucalyptus oil is used as an insect repellent and biopesticide. In the U.S., eucalyptus oil was first registered in 1948 as an insecticide and miticide.
Flavouring
Eucalyptus oil is used in flavouring. Cineole-based eucalyptus oil is used as a flavouring at low levels (0.002%) in various products, including baked goods, confectionery, meat products and beverages. Eucalyptus oil has antimicrobial activity against a broad range of foodborne human pathogens and food spoilage microorganisms.
Fragrance
Eucalyptus oil is also used as a fragrance component to impart a fresh and clean aroma in soaps, detergents, lotions and perfumes.
