Lemon balm, Melissa officinalis L. [Fam. Lamiaceae], is a wonder herb from the mint family with a pleasant lemon-scent, often taken as a tea after a meal for its ability to reduce indigestion and gas. Lemon balm tea was also traditionally used in Europe as a mild sedative and to treat headaches, migraines, nervous tension and insomnia, as well as to treat colds, fevers and coughs. Based on research, the German Commission E recognizes lemon balm for treating nervous disturbances of sleep and functional gastrointestinal disorders. Studies demonstrate that lemon balm extract significantly increases bile secretion and protects the gastrointestinal tract against ulcers. Lemon balm produces a dose dependent anti-ulcerogenic effect associated with reduced acid output, increased mucin secretion, an increase in prostaglandin E2 release and a decrease in leukotrienes. In European folk tradition, lemon balm tea was also used as an antispasmodic for treating menstrual cramps and amenorrhea. Experimentally, lemon balm can also be used against mental fatigue, poor memory, chronic fatigue syndrome, thyroid disorders and Grave’s disease. Lemon balm extract also has strong antimicrobial properties against viral, bacterial and fungal infections and can be used both internally and externally. Studies show that lemon balm extract is effective against herpes simplex, Newcastle disease and other viruses. Applied externally as a cream, lemon balm extract significantly decreases healing time of herpes mouth sores (recurring herpes labialis), prevents their spread and reduces the symptoms of itching. The aqueous extract of Melissa officinalis also has potent anti-HIV-1 activity (with an ED of 16 microg/ml). The active components in the extract were found to be water-soluble polar substances, not nonpolar compounds such as essential oils. In addition, the aqueous extract inhibited giant cell formation in cells with and without HIV-1 infection and showed inhibitory activity against HIV-1 reverse transcriptase.
Lemon balm leaves contain: 0.02-0.3% essential oil containing over 70 different components including >60% monoterpenes (ca. 30-40% citronellal; citral a and b (geranial and neral) in the ratio of 3:4-5 (ca. 10-30%); methyl citronellate; ocimene; citronellol; geraniol; and nerol); and >35% sesquiterpenes (ca. 10% beta-caryophyllene and germacrene D; germacra-1(10)E,5E-dien-ol; eugenyl glucoside; and ca. 4% rosmarinic acid (also called labiate tannin). There are also many polyphenols including chlorogenic, ferulic and caffeic acids, flavonoids, as well as triterpenes and other bitter substances in the leaves.
Lemon balm can be taken as a tea with the recommended dosage of a warm cup of tea taken three to five times a day between or after meals, or as required. The infusion of coarsely cut or powdered leaves is made using 1.5-4.5g (ca. 1 teaspoon = 1 gram) of herb material to one cup of boiling water. The boiling water is poured over the herb material and extracted for 5-10 minutes and then strained. Alternatively, 5-15g of tincture can be taken daily, or other preparations taken correspondingly. For washes, a 5% infusion is recommended.
