Native to Australia and Tasmania, eucalyptus trees were thought to promote cleaner air in the swampy areas in which they grew. Australian Aborigines used crushed eucalyptus leaves to heal wounds, fight infection, and relieve muscular pain.

 

Essential oils and teas are made from leaves. Eucalyptus is also found in cough syrups and lozenges.

Eucalyptus leaves are prepared as teas and used in cough syrups and lozenges. These preparations take advantage of the expectorant and decongestant properties of the leaves. A more common preparation is as an essential oil. Eucalyptus oil has these properties:

• Antibacterial
• Decongestant
• Astrigent
• Expectorant
• Germicide
• Cooling
• Antispasmodic
• Respiratory aid

 

Eucalyptus is used to treat respiratory problems, colds, aches, and rheumatic conditions. Inhale the vapour of eucalyptus leaves or drink a eucalyptus tea to effectively treat congestion of the respiratory tract. The leaves may be applied as a poultice to heal skin. The oil is a strong antibacterial, but should be diluted.

Do not use eucalyptus on the faces of small children. Dilute eucalyptus oil before applying to the skin. Eucalyptus is toxic in large quantities. In rare cases nausea, vomiting, and diarrhea may occur after taking eucalyptus.
