Principal Proposed Uses
- Common Cold (Oral, Lozenge, Inhaled)
The eucalyptus tree originated in Australia and Tasmania, but has now been spread to all other inhabited continents. There are many different varieties of eucalyptus, with somewhat differing constituents. The most common type used medicinally is eucalyptus globules. Its essential oil contains eucalyptol (cineol or cineole).
Eucalyptus oil has long history of use as a topical antiseptic. It has also been used as a lozenge or inhalation therapy for asthma, cough, sore throat, and other respiratory conditions.
What is Eucalyptus Used for Today?
A standardized combination of cineol from eucalyptus, d-limonene from citrus fruit, and alpha-pinene from pine has been studied for effectiveness in a variety of respiratory conditions. These oils are all in a chemical family called monoterpenes, and for this reason the combined treatment is called “ essential oil monoterpenes .” This combination is discussed in a separate article of that name. Other combination therapies containing eucalyptus oil are discussed in the article titled Aromatherapy .
The studied dosage of cineole is 200 mg three times daily for adults. Internal use of cineole or eucalyptus oil should be avoided in children.
In the gingivitis study, chewing gum containing 0.4% and 0.6% eucalyptus extracts were used.
For use as an insect repellent, 25-50 ml of the oil is added to 500 ml of water. Do not use in children under age 12.
As an inhalant, a few drops of eucalyptus oil are added to a vaporizer.
