I had no idea how many uses there are for eucalyptus oil! I ordered Essentials Co. Essential Oil to use in a diffuser. There are so many uses easily found in an online search. Essential oils are expensive, but this is affordable and easy to use! The pleasant aroma of eucalyptus oil makes it a very effective as a room freshener. While the aroma of the oil isn't as strong as the 100% eucalyptus oil given to me by my sister-in-law, this has functioned just as well for me. #theessentialsco
