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.
The volatile oil, dominated by thymol and carvacrol, gives most of the antimicrobial and antioxidant activity.
Contribute additional antioxidant 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.
Generally safe at culinary doses. Essential oil is highly concentrated and must be diluted before topical use; undiluted application can cause skin sensitisation. Not recommended internally during pregnancy (uterine stimulant effects possible). Phenol-rich thyme preparations should be avoided long-term in high doses. May potentiate anticoagulant medications.
Duke (2002) rates Thymus vulgaris (garden thyme, closely related to breckland thyme) as +++ with clinical evidence (score 2) for antibacterial, bronchospasmolytic, and antispasmodic activities, consistent with Commission E and WHO approvals for bronchitis and upper respiratory catarrh. The primary active constituent is thymol, with carvacrol as a secondary compound. Dose: 1–2 g dried herb as tea three times daily. The plant demonstrates COX-2 inhibitory activity and calcium antagonism, which may explain its antispasmodic effects (Duke, 2002).

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, mat-forming, aromatic perennial subshrub with tiny, oval, strongly aromatic leaves on trailing, wiry, hairy stems that root as they spread. Small, pinkish-purple, two-lipped flowers are borne in dense whorled clusters at the stem tips.
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, sunny heath, grassland, rocky ground and sandy soils; native to Europe and widely distributed across the northern temperate zone.
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 (flower and leaf) are cut at the start of flowering in summer and dried in a warm, shaded, airy place.
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]
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.
Dried flowering herb infused in hot water as a traditional respiratory and digestive tea.
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]
