Lemon essential oil is extracted from the Citrus limonum (also known as Citrus Limon), of the Rutaceae family and is also known as cedro oil (which refers to terpeneless oil). This clean smelling citrus essential oil is not only good for helping you make decisions and to improve your concentration, but cuts down on acidity in the body - thereby assisting the digestion, as well as with rheumatism, arthritis and gout, while also sorting out cellulite, abscesses, boils, carbuncles and acne. Oil properties Lemon oil has a sharp, fresh smell, is pale greenish-yellow in color and is watery in viscosity. The shelf life of lemon oil is only 8-10 months, if it is to be used in aromatherapy, but can still be used in fragrance therapies after this time, such as vapor therapy.
