Meet Eucalyptus
Eucalyptus (Eucalyptus spp./Eucalyptus globulus) is an evergreen tree that is part of the Myrtaceae family with more than 700 species varying from trees to shrubs. Native to Australia, it is deeply rooted in Aboriginal culture traditionally used to treat fevers, respiratory ailments and infections.
Today, eucalyptus is best known for its aromatic leaves and the essential oil they contain, particularly 1,8-cineole (eucalyptol), a compound responsible for much of its distinctive, aroma.
Traditional Herbal Actions
Its leaves are the primary plant part used medicinally and for essential oil production. They contain volatile oils, flavonoids, tannins and resin. Eucalyptus is described as warming and stimulating with several traditional herbal actions:
- Antiseptic – its essential oil has demonstrated antimicrobial activity in lab studies and is commonly used in topical and aromatic preparations
- Analgesic/Pain Relief Support – due to its warming energetic effect, a diluted essential oil can help relieve joint pain, muscle soreness and help decrease inflammation
- Expectorant – eucalyptus has traditionally been used to help clear congestion (due to its active compound cineole) by breaking up mucus when its vapors are inhaled
Traditional Uses
Cough & Respiratory Support
Eucalyptus is a common ingredient in cough drops, chest rubs and respiratory preparation. Its strong aromatic qualities can provide a cooling, refreshing sensation when used appropriately.
Insect Repellent
Oil of lemon eucalyptus is noted to be effective against ticks and mosquitos due its active compound eucalyptol. Note:oil of lemon eucalyptus (OLE) is different from eucalyptus essential oil and should not be considered interchangeable with it.
Steam
The aromatic leaves and essential oil of eucalyptus have traditionally been used in steam inhalation to create a soothing experience to help clear congestion in the nose and chest Eucalpytus can also be incorporated into a warm bath/shower or as a facial steam for its aromatic benefits.
Massage & Muscle Support
When properly diluted in a carrier oil, eucalyptus essential oil is commonly incorporated into massage oils and topical preparations intended to support tired, sore muscles.
Safety & Considerations
Eucalyptus essential oil is highly concentrated and should never be taken internally unless specifically directed by a qualified healthcare professional. Ingestion of concentrated eucalyptus oil can be toxic.
Essential oil should always be properly diluted before topical use and should be kept away from the eyes and mucous membranes.
Extra caution is recommended when using eucalyptus around young children, particularly infants and toddlers. People with asthma, seizure disorders or other medical conditions, as well as those taking medications, should consult a qualified healthcare professional before using eucalyptus essential oil therapeutically.
If using eucalyptus during pregnancy or while breastfeeding, consult your healthcare provider before use.
As with any essential oil, discontinue use if irritation or an adverse reaction occurs.
