Eucalyptus oil is a pure essential oil that has practical many healing properties. It comes from a fast-growing evergreen tree native to India and Australia, with global eucalyptus oil production mainly from Eucalyptus Globulus. Eucalyptus oil is the distilled oil that comes from the dried leaves of eucalyptus – a colorless liquid with a strong woody and sweet smell. There are more than 700 different species of eucalyptus in the world, of which at least 500 produce a type of essential oil. Diluted form of eucalyptus oil is taken orally for pain and inflammation of respiratory tract mucous membranes, coughs, asthma, bronchitis, sinus pain and inflammation, and respiratory infections. It is also used as an antiseptic, insect repellent, and treatment option for wounds, burns, and ulcer. For healing mucus membranes (such as to safely and effectively treat allergies and asthma, you can apply a drop of eucalyptus oil on an organic cotton ball and sniff it several times a day. I also recommend adding a few drops to water or a nebulizer as steam therapy, or you can use a few drops in your bath water. It is commonly mixed with other oils to make it more easily absorbed by your skin. This supports the moisturizing process, which explains the oil's presence in skin products like a natural sunscreen. There are different ways to use eucalyptus oil, including aromatically, topically, or internally. For instance, it can be applied to skin within a carrier oil, such as coconut /almond or sesame oil. Add drop added to 1 to 3 teaspoons of carrier, and increase the essential oil as necessary.
