Traditional Recipes
Parts Used
The leaves and flowering aerial parts are used. Harvest typically occurs just before flowering, when aromatic content is highest NC State Extension.
Herb Identification
Lemon balm is a perennial herb with soft, heart-shaped leaves, a pronounced lemon scent when crushed, and small white to pale yellow flowers.
It grows in clumps, reaching about 60–90 cm in height. Look-alikes include other mint-family plants, but the lemon scent is a reliable distinguishing feature NC State Extension.
Selecting Quality Herb
High-quality lemon balm should have a fresh, lemony aroma and a vibrant green color. Dull color or lack of scent often indicates age or poor storage.
Organic cultivation and gentle processing help preserve the plant’s delicate volatile compounds European Medicines Agency (EMA).
Usage Forms & Shelf Life
Internal vs external use:
Lemon balm is widely used internally as tea, tincture, or extract. Externally, it appears in creams, salves, and ointments, especially for skin applications.
Common preparations:
Infusion (tea)
Tincture
Fluid extract
Topical creams and salves
Shelf life:

Active Constituents
Lemon balm contains several well-studied groups of compounds.
Essential oils (including citral, citronellal, and geraniol):
These aromatic compounds contribute to lemon balm’s calming scent and are best preserved through gentle infusion or alcohol extraction PubMed Central.
Phenolic acids (notably rosmarinic acid):
Rosmarinic acid is one of the most studied constituents. Quantitative analyses report levels ranging from approximately 1.5 to 4.5 percent in dried leaf, depending on growing conditions and harvest timing PubMed Central.
Flavonoids:
These compounds are traditionally associated with antioxidant and calming effects and are readily extracted in water and alcohol PubMed Central.
How It Works
Lemon balm appears to influence the nervous system through interactions with neurotransmitter pathways related to calm and focus. Research has explored its effects on GABA-transaminase activity, which may help explain its traditional calming reputation PubMed Central.
Its digestive benefits are thought to arise from a combination of aromatic oils and bitter components that gently stimulate and relax digestive processes.
Side Effects & Contraindications
Side effects are uncommon but may include mild digestive discomfort in sensitive individuals. Lemon balm is generally avoided in cases of known hypersensitivity to plants in the mint family.
Due to limited data, conservative use is often recommended during pregnancy and breastfeeding European Medicines Agency (EMA).
