Origin, composition and use of eucalyptus oil in aromatherapy

One of the most versatile essential oils for aromatherapy is eucalyptus essential oil. Due to its revitalising, cleansing and rejuvenating properties, it is an important component of many natural healing methods. However, in order to realise its full potential, it is important to learn more about the history and ingredients of this essential oil.

History and origin of eucalyptus

The leaves of the eucalyptus tree, which is native to Tasmania and Australia, are used to produce eucalyptus essential oil. With almost 700 species, the eucalyptus tree belongs to the myrtle family (Myrtaceae). The best-known species from which essential oil is extracted are Eucalyptus radiata, Eucalyptus citriodora (lemon gum) and Eucalyptus globulus (blue eucalyptus).
Australia's indigenous people, the Aborigines, have used eucalyptus leaves for thousands of years as a remedy for fevers and wounds. The commercial production of eucalyptus oil by steam distillation only began in the 19th century, when it was transported from Australia to Europe and other parts of the world. Due to its numerous therapeutic benefits, it immediately made a name for itself in aromatherapy and naturopathy.

The extraction of eucalyptus essential oil

Steam distillation is used to extract eucalyptus essential oil from the young twigs and fresh leaves of the eucalyptus tree. The essential oils are released during this process by heating the leaves. The pure oil can then be extracted as soon as the rising vapour has cooled and condensed. Around 50 kilograms of eucalyptus leaves are required for one litre of essential oil, which is a considerable number of leaves to produce.
The type of eucalyptus and the place of collection have a significant influence on the quality of the oil. High-quality oils often come from sustainable cultivation areas in Australia, South Africa, Spain or China or from wild collections.

Essential components of eucalyptus

The chemical constituents that make up eucalyptus oil give it its medicinal properties. 1,8-cineole, often referred to as eucalyptol, is the main component that is primarily responsible for the health benefits. The 1,8-cineole concentration in different eucalyptus species is between 60 and 85 %.

The main components and their effects are as follows:

1-Eucalyptol or 1,8-cineole: This main ingredient has strong expectorant, antibacterial and anti-inflammatory properties. As it clears the airways and reduces mucus production in the lungs, it is often used in cough medicines and inhalation treatments.
Limonene: Limonene is another terpene contained in eucalyptus essential oil. It strengthens the immune system and has an antioxidant effect. It also gives the oil a hint of citrus fruit.
Pinene: This ingredient also has antibacterial and anti-inflammatory properties. Pinene and 1,8-cineole not only support lung function, but together they can also dilate the airways.
Citronellal and geraniol are two substances found particularly in lemon eucalyptus oil. They give the oil a citrus flavour and act as an insect repellent.
The oil may contain small amounts of flavonoids and tannins, two plant substances with anti-inflammatory and antioxidant properties.

Applications in the field of aromatherapy

Eucalyptus oil has many uses in aromatherapy and can have a positive effect on mental and physical well-being. Due to its antibacterial and anti-inflammatory properties, it is often used to treat respiratory illnesses and muscle pain as well as to promote mental clarity.

Eucalyptus essential oil is also frequently used in cough lozenges and ointments that are commercially available.

Promotion of concentration

Eucalyptus oil is often used in aromatherapy to promote concentration and mental clarity. The invigorating aroma can have a stimulating effect and promotes mental organisation. Regaining alertness and increasing mental vitality can be beneficial in stressful or mentally taxing moments.

Eucalyptus oil is an excellent painkiller due to its anti-inflammatory properties. It is often used in massage oils to relieve rheumatic symptoms and loosen tense muscles. One option is to apply a few drops of the oil directly to the painful areas after mixing it with a carrier oil such as jojoba or almond oil.
