Eucalyptus

Eucalyptus globulus
Read before use: the information below describes traditional and informational uses — it does not replace the advice of a healthcare professional. In case of doubt, pregnancy, breastfeeding, ongoing treatment or use in children, seek advice before use.
Enhanced precautions for this plant: Eucalyptus essential oil is not recommended for pregnant or breastfeeding women, as well as young children, due to its high cineole content. Never ingest pure essential oil: it is toxic by oral route even at moderate doses. Avoid any use in people with asthma or epilepsy without prior medical advice. In case of doubt or ongoing medication, consult a healthcare professional before any use, particularly by inhalation or topical application.

Steam inhalation with dried leaves

Pour boiling water over a handful of dried leaves in a container, then breathe the steam by covering your head with a towel for a few minutes. This traditional practice aims to clear the sinuses and bronchi. Dosage should be validated with a healthcare professional or a recognized pharmacopoeia before use.

Leaf infusion

Steep a few dried leaves in hot water for about ten minutes. This herbal tea was traditionally drunk to support relief from colds, outside of pregnancy periods or in young children. Dosage should be validated with a healthcare professional or a recognized pharmacopoeia before use.

Diluted chest rub

A eucalyptus essential oil highly diluted in a carrier oil may be applied as a chest rub. This preparation requires rigorous dilution and the advice of a professional trained in essential oils before use. Dosage should be validated with a healthcare professional or a recognized pharmacopoeia before use.
