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 terpinen-4-ol and cis-sabinene hydrate in true sweet marjoram, gives most of the antimicrobial and antioxidant activity.
Contribute to antioxidant and 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 very safe as a culinary herb. Essential oil should not be ingested in large amounts and avoided in pregnancy. Theoretically may interact with anticoagulants. Avoid medicinal doses during pregnancy.
Duke (2002) rates marjoram (Origanum majorana) as +++ and notes antiviral, antispasmodic, COX-2 inhibitory, and antiseptic activities at the experimental level (score 1). It demonstrates antiherpetic activity in vitro. The plant contains rosmarinic acid and thymol, which contribute to antioxidant and antimicrobial effects. Dose: 1–2 g dried herb as tea three times daily or equivalent preparations. Duke notes the plant is generally well-tolerated with no significant contraindications at usual herbal doses (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]
Tender perennial subshrub (Lamiaceae), often grown as an annual in cold climates, 20-60 cm tall, with square, downy, much-branched stems. Leaves are opposite, small, grey-green and ovate. Tiny white to pale pink, two-lipped flowers are borne in distinctive knot-like clustered spikes, the origin of the common name 'knotted marjoram'.[6]
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]
Native to Cyprus, Turkey and the eastern Mediterranean, and widely cultivated as a culinary and medicinal herb in gardens worldwide; prefers full sun and well-drained, often calcareous soils.[6]
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 aerial flowering parts are cut just before or at flowering (summer), when essential-oil content is highest, and dried quickly in a warm, shaded, well-ventilated place.[9]
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]
Marjoram has a long Mediterranean culinary-medicinal tradition as a digestive carminative and mild sedative for indigestion, cramping and poor sleep, and as an antiseptic for minor wounds and infections. Modern research confirms antispasmodic, antimicrobial, antioxidant and anti-inflammatory activity from its essential oil and phenolic constituents.[6, 8]
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.
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]
