About the Oil: Eucalyptus oil is also noted in the aromatherapy literature as having anti-viral properties, in addition to its action as an anti-microbial. Eucalyptus and Pine oils added to a spray bottle of water can be used to disinfect room air - a cold-air nebulizer or adding the oil to a humidifier can do the same. Eucalyptus Radiata is the number 1, all-purpose Eucalyptus oil. The oil is cooling, camphoraceous, stimulating, and fresh, with a bright top note. The oil and leaves of Eucalyptus are a traditional folk remedy of Australia, with the leaves of the tree being smoked like tobacco to improve asthmatic conditions. Eucalyptus essential oil is even effective as an insect repellent.

As one of the best remedies for the respiratory system, it is antiseptic, expectorant, and antispasmodic. One of its main components, Eucalyptol, is found in many over-the-counter cold remedies. An excellent way to utilize the oil's supportive properties is to add a few drops to a steaming bowl of water. The heat from the water will vaporize the essential oil, and you can inhale the moist, aromatic air to support your breathing. It may also dry up phlegm and provide relief of sinusitis.
