According to different sources, there are between 500-700 varieties of the eucalyptus tree. This is one reason there are so many eucalyptus essential oils to choose from. The one thing they all have in common is that they work to open and clear the lungs.
Eucalyptus essential oil is great when diffused into the air. It can also be used topically in diluted blends, but should not be taken orally.
The following are some of the common varieties of Eucalyptus Essential Oil that points out subtle differences in them. My favorite White Sage Landing essential oil stock will vary according to high quality organic oils that are available during each growing season.
Eucalyptus globulus: (aka blue gum) respiratory tract infections, arthritis, wounds, purifying the air. One of the most common types.
Eucalyptus citriodora: lemony, cooling, wind-heat (yellow mucous), insect repellent, mild so good choice for children.
Eucalyptus radiatta or E. australiana: (aka Eucalyptus – Peppermint) menthol, infections of sinus, ear, and kidney, vaginitis. Very gentle.
Eucalyptus dives: strongest topical medicinal value but becoming rare and difficult to find good quality. Eucalyptus macarthii is a good substitute.
Eucalyptus polybractea: (aka blue mallee) antimicrobial, expectorant, coughs and throat infections.
Eucalyptus macarthii: great disinfector, joint and muscle pain, respiratory cleanser.
Eucalyptus smithii: diffuse to clear environment of molds and bacteria.
