Medicinal use of Lemon Verbena:An undervalued medicinal herb, lemon verbena contains a strong lemon-scented essential oil that has calming and digestive qualities. The plant has a gentle sedative action and a reputation for soothing abdominal discomfort. It has a mildly tonic effect upon the nervous system and helps to lift the spirits and counter depression. The leaves and the flowering tops are antispasmodic, febrifuge, sedative and stomachic. A tea made from the leaves has a deliciously refreshing lemon flavour and is used mainly in treating digestive disorders such as flatulence, indigestion and acidity. Some caution is advisable though, since prolonged use or large internal doses can cause gastric irritation. The herb is also useful as a stimulant for treating lethargy or depression whilst it is also used to treat feverish colds. The essential oil is used in aromatherapy in the treatment of nervous and digestive problems and also for acne, boils and cysts.

Other uses of the herb:An essential oil obtained from the leaves is extensively used in perfumery. An average yield of 0.5% is obtained. There is some evidence that the use of this oil can sensitise the skin to sunlight and so its use has been largely replaced by the tropical plant lemongrass, Cymbopogon spp. The dried leaves retain their fragrance well and so are used in pot-pourri. The growing plant repels midges, flies and other insects. The essential oil is an effective insecticide in 1 - 2% concentration.
