EUCALYPTUS Greenleaf Essential Oil Acknowledged as a "cure-all" by the Aborigines, Eucalyptus is native to Australia and belongs to the Myrtaceae family. Used throughout history to treat pains, fever, and illness, Eucalyptus Oil became in high demand during World War I to treat meningitis and for the influenza of 1919. Refreshing and soothing, the oil features minty accords with citrus overtones. Each Greenleaf essential oil bottle holds 0.5 fl oz of 100% pure, natural, and undiluted essentials oils, and proceeds from this item are donated to organizations working to break the cycle of human trafficking.
