Key Constituents
The principal phenolic acid of lemon balm, associated with much of its antioxidant and antiviral activity.
The volatile oil (geranial and neral, together called citral, plus citronellal) gives the characteristic lemon scent and has demonstrated anxiolytic activity.
Minor constituents studied for anti-inflammatory activity.

Safety, Cautions & Contraindications
Generally very safe for adults. Theoretically may interact with thyroid medications and sedatives. Avoid high therapeutic doses during pregnancy. Long-term safety data beyond a few months is limited.
Traditional use only; clinical evidence is limited, so a persistent cough or digestive complaint needs medical assessment. Safety in pregnancy and breastfeeding is not established.

Botanical Description
Perennial herb, 30-70 (up to 150) cm tall, with square, branched, hairy stems typical of the mint family. Leaves are opposite, ovate to heart-shaped with a toothed margin, wrinkled and softly hairy, releasing a strong lemon scent when crushed. Small, pale yellow to white, two-lipped flowers are borne in loose whorls in the leaf axils. The fruit splits into four small nutlets.[6]
Low, creeping, mat-forming perennial herb with softly hairy, oval, finely toothed leaves along trailing stems that root as they spread. Small, pale lilac-blue flowers with darker veining are borne in slender upright spikes rising from the leaf axils.[8]
Habitat
Native to southern Europe, the Mediterranean and western Asia, widely cultivated and naturalised in gardens, hedgebanks and waste ground across temperate regions, favouring sunny to lightly shaded, well-drained soils.[6]
Grows on dry heath, moorland, open woodland, grassland and banks on acidic, well-drained soils; native to Europe and naturalised in North America.[8]
Harvesting
Leaves and flowering tops are cut just before or at the start of flowering (summer), when the volatile-oil content is highest, and dried quickly at low temperature away from direct light, since the aromatic oil is heat- and light-sensitive.[6]
The flowering aerial parts are cut in summer while in flower and dried in a warm, shaded, airy place; the closely related Veronica chamaedrys is a frequent adulterant, so careful identification (or a reputable source) is important.[8]
Traditional Uses
Lemon balm has a long European tradition as a calming, 'cheering' herb for nervous tension, poor sleep and mild anxiety, and as a carminative for indigestion, bloating and cramping; topically it has traditionally been applied to cold sores. Modern clinical trials support anxiolytic and mood-related benefits and antiviral activity against herpes simplex virus, consistent with these traditional uses.[4, 6, 9]
Speedwell has a long European folk history as a mild digestive tonic and traditional expectorant for cough and respiratory complaints, and has also been used topically as a soothing wash for irritated skin; modern research on its iridoid glycosides supports a molecular basis for the traditional respiratory use.
Preparations
Dried leaf steeped in hot water, the classic way of taking lemon balm for calming and digestive support.
Encapsulated dry extract, the form used in clinical trials studying lemon balm for anxiety and mood; follow product-specific dosing.
Concentrated leaf extract cream applied to cold sores (herpes labialis) at the earliest sign of an outbreak.
Tincture of the dried leaf, 2-6 ml one to three times daily per the EU herbal monograph. Educational reference only, not a prescription.
Not documented
Dosage
The EU herbal monograph gives 1.5-4.5 g of the comminuted leaf in 150 mL of boiling water as an infusion, 1-3 times daily, in adolescents over 12, adults and elderly; a liquid extract at 2-4 mL and a tincture at 2-6 mL, both 1-3 times daily, are also listed. If symptoms persist longer than 2 weeks a healthcare practitioner should be consulted. Not recommended under 12 years. Educational reference only, not a prescription.

Pairings
Lemon balm and passionflower are both gentle, GABA-acting calming herbs often blended together in anti-anxiety and sleep formulas; combined use may deepen relaxation but also add to drowsiness.[17, 19]
