Lemon essential oil has a tonic action on the lymphatic system and a stimulating action on the digestive system. It can be used to alleviate bilious attacks, and when combined with other essential oils, it can contribute to the treatment of verrucas, insect bites, and tension headaches. Lemon can assist the metabolic function and is useful in skin care. Although slightly sedative and calming, lemon essential oil greatly aids focus and concentration, especially when part of a blend. The fresh, clean aroma of lemon is universally liked, making it highly useful as a synergistic addition to room fragrances and perfuming blends. This antiseptic and uplifting essential oil has a place in household care and, of course, is invaluable as a flavoring agent. Lemon essential oil can be used for so many things – as a water purifier, in skin care and body treatments – it is a true allrounder.
