Traditional Uses + Modern Context
Lemon balm has been used in European herbal traditions for centuries, particularly for mild nervous tension, restlessness, and digestive discomfort. Its pleasantly aromatic leaves have also been enjoyed as a culinary herb and prepared as a gentle tea, often after meals or during periods of stress.
Modern research has explored lemon balm for anxiety, mood, sleep, cognition, and digestive effects. Some human studies have reported promising results, particularly for stress and mild anxiety, but the evidence remains limited and varies considerably by preparation and dose. Its traditional use is better established than many broader modern claims, making lemon balm best presented as a gentle calming and digestive-support herb rather than as a treatment for anxiety, insomnia, or other medical conditions.

Stress + Nervous Tension
Lemon balm is traditionally used during periods of mild stress, nervous tension, and restlessness. A warm tea or tincture can be a simple addition to a calming routine.
Digestive Comfort
Its aromatic, carminative qualities make lemon balm a traditional choice for gas, bloating, and mild digestive discomfort, particularly when digestion feels unsettled during stressful periods.
Evening Wind-Down
Lemon balm’s gentle calming qualities make it well suited to evening routines when the goal is to relax, settle the mind, and ease into a quieter end to the day.
Preparations
Lemon balm is especially well suited to simple preparations that preserve its fresh, aromatic character. The leaves can be used fresh or dried, although fresh lemon balm often has the brightest flavor and aroma.
Infusion
Fresh or dried lemon balm leaves can be steeped in hot water for a light, aromatic tea. This is one of the simplest ways to use the herb for gentle calming or digestive support.
Tincture
Lemon balm can be extracted in alcohol to create a concentrated, shelf-stable preparation. Tinctures are convenient when a tea isn’t practical or when small amounts are preferred.
Glycerite
A glycerin-based extract offers an alcohol-free option with a naturally sweet taste. It can be especially useful for people who prefer a gentler-tasting liquid preparation.
Food
Fresh lemon balm leaves have a mild lemony flavor and can be added to salads, fruit, infused water, sauces, and other foods. It works particularly well when added near the end of preparation to preserve its fresh aroma.
Growing Lemon Balm
Lemon balm is an easy-to-grow perennial in the mint family that returns year after year in many climates. Once established, it can grow vigorously and spread readily, making it a good candidate for containers or a spot where it has room to expand.
SUN
Light
Lemon balm grows well in full sun to partial shade. In hotter conditions, some afternoon shade can help protect the leaves from intense heat and keep growth lush.
CARE
Soil + Water
Plant in reasonably fertile, well-drained soil and water regularly while young plants establish. Mature lemon balm is fairly adaptable, but consistent moisture encourages tender, leafy growth.
PLANTING
Sowing + Growth
Start lemon balm from seed, cuttings, or divisions in spring. Pinching or cutting the plant back encourages bushier growth, and removing flowers before they set seed can help limit unwanted spreading.
Harvesting and Drying
Lemon balm can be harvested repeatedly throughout the growing season. Its leaves are most aromatic before flowering, although healthy leafy growth can continue to be gathered after the plant has been cut back.
When to Harvest
Harvest on a dry day after morning moisture has evaporated. For the strongest aroma, gather leaves and tender stems before the plant flowers, when its aromatic oils are especially noticeable.
What to Gather
Harvest healthy leaves and the tender upper portions of the stems. Cutting just above a leaf node encourages the plant to branch and produce fresh growth for later harvests.
Drying + Storage
Dry lemon balm promptly in thin layers with good airflow and away from direct sunlight. Once completely dry, store the leaves in an airtight container away from heat, moisture, and light to help preserve their color and delicate aroma.
Safety + Considerations
Lemon balm is generally well tolerated when used as a food or traditional herbal preparation, but concentrated or regular medicinal use deserves additional consideration, particularly with medications and during pregnancy or breastfeeding.
Thyroid Considerations
Laboratory research has raised questions about lemon balm and thyroid activity, but the clinical significance in humans is uncertain. People with thyroid conditions or those taking thyroid medication should discuss regular medicinal use with a qualified healthcare professional.
Sedatives + Medications
Because lemon balm is used for its calming effects, use additional caution when combining concentrated preparations with sedating medications or other substances that cause drowsiness. If you take prescription medications, check for potential interactions before regular medicinal use.
Pregnancy + Breastfeeding
Culinary amounts are different from concentrated herbal preparations. Safety information for medicinal use during pregnancy and breastfeeding is limited, so professional guidance is recommended before using lemon balm regularly in concentrated forms.
