Description
Lemon Eucalyptus essential oil is a fresh, uplifting, and powerfully cleansing oil distilled from the leaves of the Corymbia citriodora tree — a tall, graceful species native to Australia’s subtropical forests. Its aroma is lemony, crisp, and slightly camphoraceous, blending the cheerful brightness of citrus with the purifying depth of eucalyptus.
This oil is distinct from both Lemon and Eucalyptus globulus, combining the best properties of each. Lemon Eucalyptus contains a naturally high concentration of citronellal, which gives it its signature scent and its renowned effectiveness as a natural insect repellent and respiratory aid. Its aroma is refreshing and revitalizing, with a clean, green, lemony depth that clears the mind and brightens the spirit.
Historically, Lemon Eucalyptus has been used in traditional Aboriginal medicine for fevers, infections, and respiratory congestion. Today, it is widely recognized by natural health practitioners and even the CDC as a plant-based mosquito deterrent, thanks to its active compound, p-menthane-3,8-diol (PMD).
Physically, Lemon Eucalyptus supports respiratory health, joint comfort, and immune strength. Its antimicrobial and anti-inflammatory qualities make it useful in diffusions, chest rubs, and air-purifying blends. Emotionally, it uplifts and clarifies the mind, helping to dispel fatigue and restore focus. Spiritually, it symbolizes clarity through renewal — like a fresh breeze that clears stagnant energy and restores vitality.
In essence, Lemon Eucalyptus essential oil is the aroma of fresh air and sunlight, cleansing both the body and the atmosphere around it.
