Among the essential oils of Eucalyptus, that of Eucalyptus Globulus is undoubtedly the best known. Specialist in the lower respiratory tract, its expectorant action on the bronchopulmonary area is remarkable. It is therefore ideal in cases of bronchitis and wet coughs, but also nasopharyngitis or sinusitis, and blocked noses. Its power and effectiveness, however, reserve its use for adults. For more sensitive subjects, we prefer the use of Eucalyptus Radiata essential oil, with similar properties, Latin name: Eucalyptus Globulus Labill. Distilled part: leaves
This article was updated on 06/07/2023Vigilance! Eucalyptus Globulus essential oil is reserved for adolescents and adults. It is contraindicated for people with asthma and epilepsy without medical advice, as well as pregnant or breastfeeding women and children less than 6 years old. All methods of use are authorized, provided that the specific precautions for each are respected.
It is preferable to dilute Eucalyptus Globulus essential oil to a maximum of 20% in vegetable oil (1 drop in 4 drops of vegetable oil), to be adapted according to the age and sensitivity of the skin. .
The oral use of Eucalyptus Globulus essential oil is reserved for adolescents and adults and should be done exceptionally, and over a short period.
The use of Eucalyptus Globulus essential oil is very powerful and can cause sensitization of the respiratory tract (eucalyptol and alpha-pinene). Its diffusion is possible, diluted to 20% in other essential oils.
Eucalyptus Globulus essential oil contains allergenic biochemical components:
limonene (≤11%)
geraniol (≤0.5%)
linalool (≤0.1%)
Note: It is preferable to test the essential oil before using it (two drops in the crook of the elbow for at least 24 hours to check that there is no reaction).
Eucalyptus Globulus essential oil is highly concentrated in 1,8-cineole and alpha-pinene. These different molecules give it the following main properties:
expectorant, mucolytic ++++ (α-pinene, 1,8-cineole (eucalyptol)):
eucalyptol and alpha-pinene play a very important role in the bronchopulmonary area: they help eliminate congestion, often produced during a respiratory infection. These two molecules regulate and thin the mucus secreted in excess by the bronchi, then expel it from the respiratory tract by activating the movement of bronchial cilia.
spasmolytic, bronchodilator ++++ (1,8-cineole (eucalyptol)):
1,8-cineole present in Eucalyptus Globulus essential oil is useful for relieving a cough, thanks to its antispasmodic and bronchodilator properties. It allows the relaxation of the smooth muscles of the respiratory tract.
antibacterial, sanitizer, respiratory antiseptic +++ (α-pinene, 1,8-cineole (eucalyptol), aromadendrene):
eucalyptus Globulus essential oil has excellent bactericidal activity against certain Gram bacteria - (E.coli, P. aeruginosa) and Gram + (S. aureus). It effectively prevents their development and growth during respiratory infections. It is also used in diffusion, in synergy with other essential oils, to disinfect or sanitize the ambient air and the respiratory tract.
antifungal ++ (α-pinene, 1,8-cineole (eucalyptol)):
the fungicidal activity of Eucalyptus Globulus has been verified on several strains of fungi in in vivo studies, and in particular the fungus responsible for bronchopulmonary aspergillosis (Aspergillus fumigatus) and that of candidiasis (Candida). The essential oil would have an inhibitory effect on the growth of these fungi, but in-depth studies are necessary to understand its mode of action.
antiviral++ (α-pinene, 1,8-cineole (eucalyptol)):
eucalyptus Globulus essential oil is capable of slowing the progression of the virus in the body in order to stop it as quickly as possible. Indeed, its major compounds, eucalyptol, and alpha-pinene, have an antiviral action by inhibiting intracellular replication. This property has been demonstrated in particular on the infectious bronchitis virus (IBV).
anti-inflammatory ++ (1,8-cineole (eucalyptol)):
during a respiratory disease, cytokines are secreted by the body in response to this attack, inducing an inflammatory defense process. Eucalyptus Globulus essential oil modulates this immune response by inhibiting the production of leukotriene B4 or interleukin 1-β for example, molecules involved in respiratory tract diseases and mucus hypersecretion.
immunomodulating ++ (1,8-cineole (eucalyptol)):
eucalyptus Globulus essential oil can be used to stimulate immunity, to help the body fight an infection or for prevention. It is capable of increasing the secretion of gamma-globulins and beta-globulins, two proteins of the immune system.
insecticide + :
eucalyptus Globulus essential oil has been shown to be effective against house flies (Musca domestica). In this study, the insecticidal activity of the essential oil was evaluated on fly larvae and pupae. The activity of Eucalyptus Globulus demonstrates its potential as an environmentally friendly product for the fight against house flies.
analgesic + (1,8-cineole (eucalyptol)):
eucalyptol is an activator of TRPM8 (cold-sensitive receptor) causing local anesthesia by sensation of cold. It is also an inhibitor of TRPA1, a receptor involved in triggering pain signals and activated by inflammatory mediators. These two associated mechanisms seem really effective in blocking pain induced by inflammation.
But also these secondary properties:

Eucalyptus Globulus essential oil is effective on most ENT infections, but Ravintsara remains the reference to help immunity. Through the skin, 3 drops of Ravintsara on the wrists and breathe deeply, for prevention, once a day, during risky periods. Take a one-week break after three weeks of use.
Eucalyptus Globulus essential oil is used on many occasions, particularly linked to its decongestant and antiseptic properties in the respiratory tract. For the majority ofthe following uses it will be effective, but without necessarily being the best essential oil. We therefore indicate to you the best replacement for Eucalyptus Globulus for the following different problems.
Eucalyptus Globulus has analgesic properties, but... for muscle pain, it is better to usewintergreen essential oil : via the skin, gently massage with 1 drop in 4 drops of vegetable oil on the affected area, 4 times a day, until improvement.
Eucalyptus Globulus has insecticidal properties, but... l'java Lemongrass essential oil remains the best, especially against mosquitoes: cutaneously, dilute 1 drop in 4 drops of vegetable oil to apply to exposed parts of the body.
Eucalyptus Globulus essential oil is active against Staphylococcus aureus, but... depending on the infection and the origin, other essential oils are more interesting such as Tea Tree or theGreen Oregano. Seek advice from a healthcare professional.
Eucalyptus Globulus is not really suitable for cystitis or urinary infections... it is better to use themountain Savory essential oil : through the skin, dilute 1 drop of Mountain Savory in 9 drops of vegetable oil by massaging on the lower abdomen, 3 times a day for 7 to 10 days.
Eucalyptus Globulus could be effective, but... l'tea Tree essential oil is the anti-infective par excellence: apply locally using a cotton swab previously soaked in vegetable oil, or dilute to 20% (1 drop in 5 drops of vegetable oil) depending on the surface of application.
Eucalyptus Radiata, Lemon Eucalyptus, Eucalyptus Globulus or Eucalyptus Smithii? Which essential oil for which use?
