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.
Phenolic monoterpenes responsible for the antimicrobial and expectorant actions.
Antioxidant and anti-inflammatory constituents.

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.
Culinary amounts are safe. Thyme essential oil is a strong irritant - dilute well before any topical use and do not take the undiluted oil internally.
A cough that persists beyond about a week, or with fever or breathlessness, needs medical assessment. Avoid medicinal/oil doses in pregnancy; allergy is possible in people sensitive to the mint family (Lamiaceae).

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, woody-based aromatic perennial subshrub with small, narrow, grey-green leaves and small, pale pink to lilac, two-lipped flowers borne in whorled clusters along the upper stems.[11]
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, rocky, well-drained soils; native to the western Mediterranean and widely cultivated as a culinary and medicinal herb worldwide.[11]
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 just as flowering begins, when essential oil content is highest, and dried in a warm, shaded, airy place; essential oil is obtained by steam distillation of the fresh or dried herb.[11]
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]
Thyme has a long Mediterranean and European tradition as an antimicrobial and expectorant remedy for coughs, bronchitis and sore throat, formalised in EU herbal monograph recognition, with a fixed thyme-ivy extract combination shown superior to placebo for acute bronchitis with productive cough in clinical trial.[11, 13]
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 herb infused in hot water as a traditional cough, cold and digestive tea.
Infusion used as a gargle for sore throat, drawing on the antiseptic essential oil constituents.
Standardized fluid extract, often combined with ivy leaf, the form studied in clinical trials for acute bronchitis.
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.
The EU herbal monograph suggests around 1-2 g of dried herb per cup, up to three times daily. Educational reference only, not a prescription; do not take the essential oil undiluted internally.

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]
