Lemon essential oil has a fresh, uplifting aroma that cleanses the air and eliminates odors when used aromatically. Originally native to Asia, the lemon tree wasn’t common in Europe until the 16th century. It is part of the evergreen family and reaches a height of about 20 feet. Lemon essential oil is known for its cleansing properties, and it is widely used in skin care and home cleaning solutions for these benefits. Its fresh, zesty aroma also makes it an important top note in perfumes, as well as an effective odor neutralizer when diffused.
