Eucalyptus has strong antiseptic properties & is widely recognised for its affinity with the respiratory system. It is also mentally & physically stimulating & can be helpful for fatigue related conditions, especially after recovering from colds & flu. Eucalyptus Smithii is the mildest of the Eucalyptus oils & is therefore the preferred choice for use with children & the elderly, or when prolonged use is required. Try blending with woody, herbaceous & citrus oils such as Basil, Cedarwood, Citronella, Ginger, Lemon, Cajeput, Frankincense, Spearmint, Lavender & Tea Tree.
