Key Constituents

Rosmarinic acid and phenolic acids[4, 6]

The principal phenolic acid of lemon balm, associated with much of its antioxidant and antiviral activity.

Rosmarinic acid
Essential oil (citral, citronellal)[4, 10]

The volatile oil (geranial and neral, together called citral, plus citronellal) gives the characteristic lemon scent and has demonstrated anxiolytic activity.

Essential (volatile) oilCitral (neral / geranial)
Flavonoids[4]

Contribute to the antioxidant activity of the leaf.

Flavonoids
Triterpenic acids (ursolic acid, oleanolic acid)[4]

Minor constituents studied for anti-inflammatory activity.

Iridoid glycosides (aucubin, catalpol, verproside, verminoside)[8]

Anti-inflammatory constituents that inhibit pro-inflammatory mediators in lung cells.

Safety, Cautions & Contraindications

Safety note[12, 13, 14]Caution

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.

Safety note[12, 13, 14, 15]Info

Duke (2002) does not include a dedicated entry under 'Lemon Balm' or 'Melissa' in the Handbook of Medicinal Herbs, Second Edition.

Safety note[11]Caution

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.

Safety note[2, 8]Info

Buy from a reputable source: Veronica officinalis is frequently adulterated with the related Veronica chamaedrys.

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]

Height: 30-70 (up to 150) cm
Habit: Erect, bushy perennial herb
Leaves: Opposite, ovate to heart-shaped, toothed, wrinkled, lemon-scented when crushed
Flowers: Small, pale yellow to white, two-lipped, in loose axillary whorls
Stem: Square, branched, hairy
Root: Fibrous, spreading perennial rootstock
Fruit: Four small nutlets (typical Lamiaceae schizocarp)
Flowering Period: June-August

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]

Height: 5-40 cm (upright flowering spikes; creeping stems low)
Habit: Low, creeping, mat-forming perennial herb
Leaves: Softly hairy, oval, finely toothed, opposite
Flowers: Small, pale lilac-blue with darker veining, in slender upright axillary spikes
Stem: Trailing, softly hairy, rooting as it spreads
Root: Fine roots along the creeping stem
Fruit: Small, flattened, heart-shaped capsule
Flowering Period: May-August

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]

Parts: Leaf, Flowering tops
Season: Summer, just before or at flowering

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]

Parts: Aerial parts (flowering herb)
Season: Summer, at flowering

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

Infusion (tea)[6]

Dried leaf steeped in hot water, the classic way of taking lemon balm for calming and digestive support.

Standardised extract capsule[1, 2]

Encapsulated dry extract, the form used in clinical trials studying lemon balm for anxiety and mood; follow product-specific dosing.

Topical cream[8]

Concentrated leaf extract cream applied to cold sores (herpes labialis) at the earliest sign of an outbreak.

Tincture[11]

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

Infusion (tea)[11]

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.

Standardised extract[1, 2]

Clinical trials for anxiety and mood have used standardised dry-extract capsules; dosing varies by product concentration, so follow the manufacturer's guidance. Educational reference only, not a prescription.

Drug Class Interactions

Safety note[16, 17, 18]Caution
Drug Class: sedatives-cns-depressants
Mechanism: Lemon balm has calming, sedative effects (a randomised controlled trial found it reduces anxiety, stress and sleep disturbance); taken with sedatives, sleeping tablets or other central-nervous-system depressants (including alcohol) it may add to drowsiness and slowed reactions.

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]
