Uses of Eucalyptus Oil - MedicineHow

Uses of Eucalyptus Oil

Just like Tea Tree oil, Eucalyptus is a plant native to Australia. It is widely thought that the plant was discovered in the late 17th century. It was used in a variety of ways from ointments to teas, and in the potent eucalyptus oil. Not until much later was it discovered that the medicinal properties were vast and could be tapped for their uses.

A Final Note

While Eucalyptus oil has many wonderful uses the cautions must be adhered to. I would suggest starting small with this oil. Using it as a room freshener is a great way to begin or by using it for a topical use in small amounts. I also recommend blending it with another oil such as lavender or tea tree but do so in a carrier oil to avoid adverse effects on the skin.

If you do decide to use for bronchial infections, I would suggest starting with a drop in a hot shower and let the steam lift the aroma and medicinal properties to you. Close your eyes when you use it as it may irritate your eyes due to the oil’s strong aroma and constituents. If you follow these rules and cautions, you can use this oil to make your life and the lives of your family members even healthier!
