In North America, Melissa officinalis has escaped cultivation and spread into the wild.
Lemon balm requires light and at least 20 degrees Celsius (70 degrees Fahrenheit) to germinate.
Lemon balm grows in clumps and spreads vegetatively as well as by seed. In mild temperate zones, the stems of the plant die off at the start of the winter, but shoot up again in spring. Lemon Balm grows vigorously and should not be planted where it will spread into other plantings.
Melissa officinalis may be the "honey-leaf" (μελισσόφυλλον) mentioned by Theophrastus. It was in the herbal garden of John Gerard, 1596. There are many cultivars of Melissa officinalis, such as:
M. officinalis 'Citronella'
M. officinalis 'Lemonella'
M. officinalis 'Quedlinburger'
M. officinalis 'Lime'
M. officinalis ‘Variegata’
M. officinalis ‘Aurea’
(M. officinalis ‘Quedlinburger Niederliegende’ is an Improved variety bred for high essential oil content.)
Lemon balm is often used as a flavouring in ice cream and herbal teas, both hot and iced, often in combination with other herbs such as spearmint. It is also frequently paired with fruit dishes or candies. It can be used in fish dishes and is the key ingredient in lemon balm pesto. It has been suggested that it might be a better, healthier preservative than beta hydroxy acid in sausages.
Uses in traditional and alternative medicine
Melissa (Melissa officinalis) essential oil in a clear glass vial
In the traditional Austrian medicine Melissa officinalis leaves have been prescribed for internal (as tea) or external (essential oil) application for the treatment of disorders of the gastrointestinal tract, nervous system, liver and bile.
Lemon balm is the main ingredient of Carmelite Water, which is still for sale in German pharmacies.
High doses of purified lemon balm extracts were found to be effective in the amelioration of laboratory-induced stress in human subjects, producing "significantly increased self-ratings of calmness and reduced self-ratings of alertness." The authors further report a "significant increase in the speed of mathematical processing, with no reduction in accuracy" following the administration of a 300 mg dose of extract.
Lemon balm is believed to inhibit the absorption of the thyroid medication thyroxine.
The crushed leaves, when rubbed on the skin, are used as a repellent for mosquitoes.
Lemon balm is also used medicinally as an herbal tea, or in extract form. It is used as an anxiolytic, mild sedative, or calming agent.[medical citation needed] At least one study has found it to be effective at reducing stress, although the study's authors call for further research. Lemon balm extract was identified as a potent in vitro inhibitor of GABA transaminase, which explains anxiolytic effects. The major compound responsible for GABA transaminase inhibition activity in lemon balm was then found to be rosmarinic acid.
Its antibacterial properties have also been demonstrated scientifically, although they are markedly weaker than those from a number of other plants studied. The extract of lemon balm was also found to have exceptionally high antioxidant activity.
Lemon balm is mentioned in the scientific journal Endocrinology, where it is explained that Melissa officinalis exhibits antithyrotropic activity, inhibiting TSH from attaching to TSH receptors, hence making it of possible use in the treatment of Graves' disease or hyperthyroidism.
