Evidence scores (1–10) are computed from the tier of each cited source. “Comparable” means the two scores are within one point. Follow a score to its detailed sources.
Key Constituents
Intensely bitter sesquiterpene lactones responsible for the classic digestive-bitter action.
Volatile oil containing thujone (alpha- and beta-isomers), the neurotoxic ketone that limits safe internal use, along with other monoterpenes.
Antioxidant constituents contributing to the plant's antioxidant activity.
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.
Pharmacological Actions
Artemisia absinthium (wormwood) total flavonoids and its constituent alpha/beta-thujone induce ROS- and caspase-mediated apoptosis in cervical and choriocarcinoma cancer cells (preclinical).
Traditional & Indicated Uses
inferred from anti-inflammatory action
inferred from antidiabetic action
Artemisia absinthium (wormwood) total flavonoids (cynaroside, astragalin) inhibit HeLa cervical cancer cells via ROS-mediated apoptosis, and its terpenoid alpha,beta-thujone induces caspase-dependent apoptosis in choriocarcinoma cells and sensitizes them to paclitaxel (preclinical).

Safety, Cautions & Contraindications
CAUTION: Contains thujone, which is neurotoxic in significant amounts. Internal use should be limited in duration and dose — short-term use only (under 4 weeks). Contraindicated in pregnancy (powerful uterine stimulant). Avoid in epilepsy, renal disease, and in children. The small amounts present in properly prepared bitter tinctures and vermouth are generally considered safe. The thujone content of absinthe was historically exaggerated.
Duke (2002) rates wormwood as + (use with caution) and provides clinical evidence (score 2) for use as an aperitif and bitter digestive tonic, consistent with Commission E approval for dyspeptic complaints and loss of appetite. The plant contains absinthin and artabsin (bitter sesquiterpene lactones) responsible for digestive stimulation, and also thujone — a neurotoxic ketone that is the active agent responsible for 'absinthism' (historical neurological syndrome linked to absinthe consumption). Duke strongly cautions that thujone content limits safe long-term use, and wormwood should not be taken internally for more than 4 weeks at a time. Strictly contraindicated in pregnancy (abortifacient, neurotoxic) and epilepsy (Duke, 2002).
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.

Botanical Description
Aromatic, silvery-grey perennial herb with finely divided, silky-hairy leaves and numerous small, pale yellow, drooping, globe-shaped flower heads borne in loose branched panicles. The whole plant has a characteristic intensely bitter taste and a pungent, sage-like aroma.[4]
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]
Habitat
Grows on dry, sunny, stony or waste ground, roadsides and field margins; native to Europe, North Africa and temperate Asia, and naturalised in North America.[4]
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]
Harvesting
The flowering aerial parts (leaf, stem and flower) are cut as flowering begins, in mid- to late summer, and dried in a warm, shaded, airy place.[4]
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]
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 flowering herb infused briefly in hot water as a very bitter digestive tea, taken before meals to stimulate appetite.
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
Because of its thujone content, traditional herbal references limit internal use to small bitter doses (around 0.5-1 g dried herb per cup) for no more than about 4 weeks at a time. Educational reference only, not a prescription.
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.

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]
