DescriptionEucalyptus leaves or oil are often employed in steam inhalations for their expectorant, antiseptic, antibacterial, and decongestant properties. A tea from the leaves has been used traditionally for aching joints, muscle stiffness, dysentery, and ringworm. Eucalyptus oil is given internally, in small doses (only 1-2 drops), most often as an ingredient in cough medicines or lozenges. The oil is also used as a natural flea repellant. Eucalyptus oil steam inhalations are often beneficial for chronic coughs and plugged sinuses.
