Eucalyptus oil contains many valuable biological substances, each of which affects the human body in a different way. Its main component is eucalyptol, which shows anti-inflammatory, antiseptic, and antibacterial effects. Thanks to these properties, the natural essential oil obtained from eucalyptus leaves is used in preparations for both internal and external use.

How does eucalyptus oil work and what is it used for? For which ailments can it be helpful? Is eucalyptus poisonous?

What Exactly Is Eucalyptus?

The first known and described species of eucalyptus is the Tasmanian blue gum (Eucalyptus globulus). It was discovered in Tasmania by French researchers at the end of the 18th century. Belonging to the myrtle family, eucalyptus also grows in Australia, Portugal, Spain, China, Brazil, India, and South Africa. The plant’s name comes from the Greek words eu (well) and calyptus (covered).

The main herbal raw material is fresh eucalyptus leaves, from which pure eucalyptus oil is produced. It is obtained through steam distillation of the plant material. Because of its properties and the richness of its chemical compounds, eucalyptus essential oil is used not only in herbal medicine, but also in cosmetics and perfumery.

Types Of Eucalyptus Oil

The essential oil obtained from eucalyptus tree leaves is an oily, colorless liquid with a strong, pleasant scent. One of the most popular and most commonly used eucalyptus oils is the preparation made from the leaves of Eucalyptus globulus. On the market, you can also find oils from other species of the plant:

  • Eucalyptus radiata – with a delicate mint-floral aroma, often chosen for fragrance burners.
  • Eucalyptus citriodora – with a citrus note, widely used in medicine and the perfume industry.
  • Eucalyptus dives – distinguished by a fresh minty-fruity aroma, perfect for inhalations.

Each of the above eucalyptus oils has slightly different uses, which is why it is worth knowing how to choose the right product for your needs. When buying this natural remedy, you should also pay attention to the purity of the product, its origin, and the method of extraction.

Eucalyptus Oil – Properties And Effects

Eucalyptus leaves are a source of many valuable substances with antiseptic, anti-inflammatory, analgesic, and antioxidant properties. The dominant component of natural eucalyptus oil is eucalyptol (1,8-cineole) – an organic chemical compound that belongs to natural terpenoids. Its content in the preparation depends on the plant’s origin and ranges from 70 to 85%.

Eucalyptol contained in eucalyptus oil has anti-inflammatory and antibacterial effects. For this reason, it is often used to combat respiratory infections (cold, flu, sinusitis). Thanks to its properties, it makes breathing easier and reduces the feeling of nasal congestion. In addition, 1,8-cineole has antibacterial and refreshing effects, which is why it is used in the production of oral hygiene products (toothpastes, mouthwashes, etc.).

Eucalyptus oil also contains other compounds such as camphene, limonene, p-cymene, and globulol. These substances act as cleansing, antioxidant, and antimicrobial agents. Current analyses also confirm the antibacterial properties of eucalyptus oil, effective against both gram-negative bacteria such as Escherichia coli and gram-positive bacteria such as Staphylococcus aureus.

What Is Eucalyptus Leaf Oil Used For?

Thanks to its fresh, pleasant scent, eucalyptus oil is widely used in aromatherapy, right next to tea tree, rosemary, and lavender oils. Eucalyptus essential oil helps relax, reduce stress, and improve concentration. It also has a regenerating effect, strengthening and stimulating the nervous system.

Eucalyptus leaf oil also works perfectly for massages, soothing tired and sore muscles. In this case, it is important to always dilute it in a carrier oil (such as jojoba oil or coconut oil). Just add 2–3 drops of eucalyptus oil to 10 ml of carrier oil. Before using it for the first time, it is also recommended to perform a patch test on a small area of skin to rule out allergic reactions.

What else does eucalyptus oil help with? This natural remedy is excellent for colds and upper respiratory infections. It acts as a pain reliever, expectorant, and antispasmodic. To soothe inflammation and sore throat, simply add a few drops of eucalyptus oil to a diffuser or hot water.

In cosmetics, eucalyptus oil is used for skin care. It is especially recommended for irritation, itching, insect bites, and skin inflammations. Many people also use it for oily hair care and dandruff treatment – all you need to do is combine eucalyptus oil with shampoo or an anti-dandruff scalp tonic. In addition, eucalyptus drops work great as a natural insect repellent and air freshener.

Is Eucalyptus Oil Safe?

Thanks to its wide range of effects, eucalyptus oil is very popular among people looking for natural ways to strengthen the immune system or relieve muscle pain. But is its use safe? Are there any contraindications to using eucalyptus oil?

Eucalyptus oil should not be applied directly to the skin in its pure form – it must be diluted in a carrier oil before use. Special caution is advised for people with heart disease and high blood pressure. Women during pregnancy and breastfeeding should consult their doctor before using eucalyptus oil.

Eucalyptus Oil And Other Essential Oils

Eucalyptus oil works very well in combination with other essential oils, allowing the creation of various aromatic and therapeutic blends. Together with lavender or peppermint oil, it stands out with a fresh, slightly “camphor-like” scent and very strong antiseptic properties. It also blends perfectly with lemon or rosemary oil.
