What lemon balm is
Lemon balm is a soft-leaved perennial herb native to south-central Europe, the Mediterranean basin and Central Asia, now naturalised and grown in gardens the world over. Its botanical name, Melissa officinalis, comes from the Greek word for a honeybee, and that is no accident: bees adore it, and old beekeepers rubbed the leaves inside a new hive to settle a swarm and keep it home. It is easy to grow, generous to the point of spreading, and happiest in a little shade with room to sprawl.
Appearance
Lemon balm forms a low, bushy clump of upright square stems, the tell-tale sign of the mint family. Its leaves are heart-shaped to oval, bright green, softly wrinkled and gently toothed at the edges, growing in opposite pairs. In summer it sends up small, pale, two-lipped flowers in white or the softest yellow, tucked where the leaves meet the stem, humming with bees. Brush past it and the whole plant releases its scent.
Fragrance and taste
Crush a leaf and the scent is pure, sweet lemon with a green, minty freshness underneath, bright and cheering rather than sharp. The taste follows: lemony and lightly sweet, faintly minty, with none of the sourness of an actual lemon. It is this soft citrus character, gentle and gladdening, that makes lemon balm as lovely in a calming tea as it is scattered over fruit or steeped in a summer cordial.
Constituents
Lemon balm's cheer comes from a fragrant blend of aromatic and antioxidant compounds. The most notable are the volatile oils citral, citronellal and geraniol, which give it that lemony lift, along with rosmarinic acid, a strong antioxidant shared with rosemary and other mint-family herbs, and a range of flavonoids. Together these lend lemon balm its scent, its gentle calming and mood-lifting reputation, and the antiviral quality behind its traditional use on cold sores.
Herbal actions
Herbalists have long loved lemon balm as a brightening nervine, a herb that calms without dulling and lifts a low mood. It is also considered a carminative that eases a nervous, windy stomach, a gentle mild sedative for restless sleep, and, applied topically, a gently antiviral herb traditionally used on cold sores. Its whole character is soothing yet uplifting, which is a rare and welcome pairing.
Traditional and modern uses
Lemon balm is the plant of good cheer. The Roman writer Pliny and the Greek physician Dioscorides both wrote of it, and the medieval physician Avicenna said it made the heart merry. The Swiss physician Paracelsus is said to have called it the elixir of life, and for centuries it was carried in cordials and calming waters to ease melancholy and settle the nerves. Traditionally it has been used to lift the spirits, quiet an anxious mind, soothe a nervous stomach, and, as a strong infusion dabbed on the skin, to help with cold sores.
Modern interest echoes the old lore, gently. Some studies suggest lemon balm may help ease stress, mild anxiety and low mood, and there is real laboratory interest in its antiviral action against the cold-sore virus. Hold these as promising rather than proven, enjoy lemon balm for the light, glad feeling it brings, and read our honest note below.
Lemon balm in astrology and correspondences
In traditional herbal astrology lemon balm belongs to Jupiter. The seventeenth-century herbalist Nicholas Culpeper, whose Complete Herbal paired every plant with a planet, wrote that it is a herb of Jupiter and under Cancer, a watery, tender sign well suited to a herb of the heart. That Jupiterian, watery character fits its whole personality: warm, expansive, kindly and gladdening, a herb that opens and softens the feelings. Remember that these correspondences are a symbolic language, not proven fact, and lemon balm is traditionally linked with Jupiter's themes of good cheer, healing and open-heartedness.
Rituals lemon balm is good for
Few herbs are as tender on the altar as lemon balm, a herb for the heart and the spirits.
- Lifting the spirits. Steep it as a bright tea, or add a handful to a herbal bath when you need gladness and a lighter heart.
- Easing grief. A gentle companion in mourning work: keep a sprig close, or float it in moon water for a soft, comforting wash.
- Love and friendship. Long counted among the herbs for love, carried to draw affection and sweeten the bonds between people.
- Calm before rest. Slip dried lemon balm into a sleep sachet or evening tea to quiet a busy, worried mind.
- Blessing new beginnings. Its old link with bees and swarms makes it lovely in rituals for a new home, a fresh start or the settling of a restless household.
How to use lemon balm
- As a tea. The simplest medicine of all: steep a good handful of fresh leaves or a spoon of dried in hot water for a bright, calming cup, lovely in the evening.
- In the kitchen. Scatter fresh leaves over fruit, salads or fish, or steep them in a summer cordial or jug of water.
- As a tincture or glycerite. See our guides to making a tincture and to herbal preparations for a longer-keeping way to hold its cheer.
- In the bath or on the skin. Add a strong infusion to bathwater to soften and calm, or dab cooled tea on a cold sore as tradition suggests.
Is lemon balm safe?
As an everyday tea and a culinary herb, lemon balm is very safe and gentle, and much loved for it. A single sensible caution applies to stronger, medicinal use: in large medicinal doses it may affect thyroid function, so take particular care, or seek advice first, if you have a thyroid condition or take thyroid medication. As always, identify your plant with certainty, and treat herbalism as a companion to medical care, not a substitute.
Does lemon balm really work?
Honestly, lemon balm is both a genuine herb and a beautiful symbol, and it helps to hold both. Its calming, mood-lifting reputation has some real, if still modest, research behind it, and its antioxidant and antiviral compounds are real, so we will not overstate it. What is certain is the small, glad lift that comes from a warm lemon-scented cup at the end of a heavy day, part scent, part ritual, part the simple act of pausing. I reach for lemon balm on the days that feel too much, as much for the brightness of the smell as anything the books promise.
