Key benefits
  • Central nervous system relaxant
  • Adaptogenic
  • Anxiety symptoms
  • Digestive complaints
  • Stress-related digestive upsets
  • Low mood
  • How does it feel?

    Lemon balm grows widely in gardens and makes a great plant for anyone to grow themselves, even in a window box. Look out for its characteristic light green leaves: picking and sniffing a leaf will tell you immediately you have the right plant. There is that wonderful aromatic lemony aroma. Chew a piece and the bright, citrusy taste comes through straightaway: the strong aromatic lemon flavour is combined with subtle hints of mint; the slight lemon acidity and tannic astringency combined with a real sweetness.

    Lemon balm delivers its properties immediately. This is clearly a gentle, soothing yet uplifting remedy, acceptable to everyone from the very youngest of age.

  • What can I use it for?

    Lemon balm is of particular use where a digestive upset is exacerbated by stress and anxiety. It is great for children, who may prefer the taste to chamomile.

    This relaxant effect has also been useful where stress affects the chest and heart, with symptoms like palpitations and hyperventilation: these in turn may be associated with acid reflux, hiatus hernia, associated symptoms that can arise when the digestion is stressed.

    Lemon balm tea also has a gentle lifting effect that can be very comforting in low moods. Indicated in anxiety, tension and mild-depression it also used for conditions characterised by nervous pain such as fibromyalgia but also in neuralgia and numbness (11).

    A primary herb of the nervous system, lemon balm is an excellent herb of choice for stress and anxiety. Like chamomile, it can be used where nervous tension causes digestive symptoms such as indigestion, flatulence and IBS (11).

    It is an effective vasodilator ad diaphoretic, which can be used to gently support circulation in the periphery. These actions are also well applied in the management of a fever (13).

    Lemon balm essential oil, or highly concentrated extracts have demonstrated benefits in relieving the symptoms of oral herpes infections or cold sores. However this effect is unlikely to be found with the herb on its own.

  • Into the heart of lemon balm

    Lemon balm is both sour and sweet, with aromatic and bitter qualities. Energetically, lemon balm is cooling, a classic action of a herb with sour/ sweet/ bitter taste qualities. A herb that has a dynamic sensory profile, that engages our nervous system on multiple levels.

    As a primary herb of the nervous system, lemon balm is an excellent herb of choice for stress and anxiety. Like chamomile, it can be used where nervous tension causes digestive symptoms such as indigestion, flatulence and IBS. However, it will be less appropriate where metabolic excess in the stomach is the cause of digestive problems. A herbalist would always assess the full picture of health to gain an understanding of the root cause and prescribe accordingly. 

    Lemon balm works well in a tense, ‘excited’ tissue state- this patient will often have a sharp, tense possibly irregular pulse, palpitations, raised blood pressure and brightly red or pink tongue. This symptom picture often indicates sympathetic nervous system (SNS) excess in a patient-  often caused by prolonged exposure to stress (see ‘nervous system’ under ‘What practitioners say’ for more information on SNS excess). 

    As often found with aromatic herbs of the mint family, lemon balm improves mental clarity. All herbs with aromatic chemistry will have a direct effect on the emotional axis of the brain, due to the relationship between the parts of the brain that process smell and the part the processes emotions (the olfactory system and the limbic system). 

    Lemon balm is cold in the second degree by the Galenic classification; qualifying the heat of the stomach, aiding digestion; abating to the heat of a fever; and ‘to refresh the spirits almost suffocating’. A ‘relaxant’ which is less than sedative and unlikely to depress, yet able to create a sense of calm and uplift.

    The blend of its powerful aromatic compounds and grounding cooling bitters are able to reassure the gentleness of its calming and cooling actions. A truly beautiful balance for one of the most reliably calming family remedies that can be safely used by anyone, with a flavour that is widely enjoyed by all ages.

    In the Ayurvedic understanding, lemon balm is a wonderful cooling remedy for excess pitta. A great medhya herb, enhancing memory and circulation, excellent for disturbance of sadhaka pitta causing anxiety, fear of failure, low self-esteem and insomnia. It clears excess pitta from rasa and rakta dhatus, calming the heart and cooling heat in eyes and mutravahasrotas. Anulomana; a good remedy for stress related digestive problems.

  • Traditional uses

    Lemon balm was originally one of the stand-by remedies for the home-management of fever. Many of its modern uses apply the same characteristics: safe, gently calming, vasodilatory (opening the peripheral blood circulation) and antispasmodic properties.

    Lemon balm was described by Culpepper as a herb that ‘causes the mind and heart to become merry and reviveth the heart’. This can be said to be applied to both the physical and emotional heart. Lemon balm is well-known for its uplifting effect which can be applied in depressive emotional states, lifting states of gloom and despair. 

    Lemon balm is also traditionally used to support fertility and has long been used in love potions for fertility and as an aphrodisiac. Lemon balm has a strong sexual connotation, especially for women who have experienced sexual trauma, believed to help reconnect with a sense of femininity, rebuilding a sense of integrity and wholeness.

  • Traditional actions

  • Traditional energetic actions

    Herbal energetics are the descriptions Herbalists have given to plants, mushrooms, lichens, foods, and some minerals based on the direct experience of how they taste, feel, and work in the body. All traditional health systems use these principles to explain how the environment we live in and absorb, impacts our health. Find out more about traditional energetic actions in our article “An introduction to herbal energetics“.

  • What practitioners say

    Digestive: Lemon balm has carminative and antispasmodic properties and is indicated in flatulence, dyspepsia, spasms and generalised indigestion; particularly where this is exacerbated by anxiety and stress. It can be helpful for heartburn and indigestion, assisting the absorption of nutrients, particularly fatty foods (as with many herbs from the mint family). 

    Cardiovascular and heart: It is a gentle circulatory tonic that dilates the peripheral blood vessels, lowers high blood pressure and relieves stress-related symptoms such as palpitations or angina. 

    It is the effects of lemon balm on the sympathetic nervous system (see notes under ‘nervous system’ below) that produce its therapeutic effects on the heart, particularly where an increased heart rate and blood pressure are a result of sympathetic overactivity) (14).

    Nervous system: Lemon balm is an important herb for the nervous system, particularly where there is sympathetic excess. The sympathetic nervous system (SNS) is a branch of the Automatic nervous system (ANS) that governs ‘stress hormones’ such as adrenaline and cortisol- which through periods of prolonged stress exposure lead to excessive sympathetic function. 

    The SNS controls blood pressure, pulse rate, gut motility and almost all of our internal organs, where ‘action and alertness’ are involved (13, 14).

    Indicated in anxiety, tension and mild-depression, also in conditions characterised by nervous pain such as fibromyalgia but also in neuralgia and numbness.

    Respiratory system: Used as a relaxant remedy for asthma and spasmodic coughs. A herb that is often used during viral respiratory infections to manage fever symptoms, by increasing sweat production and reducing a viral fever (11).

    Immune system: Lemon balm is an effective treatment for herpes simplex virus (coldsores). The essential oil (diluted) or cream of lemonbalm can be applied to the affected area (10). Taken as a tea or tincture orally, lemon balm may also help with the virus systemically but for topical treatment of coldsores, an essential oil based preparation must be used.

    Metabolism: Lemon balm looks to be a promising long-term complement to dietary control of the metabolic syndrome that often merges into late onset diabetes (7).

  • Research

    Herbal tea in a glass cup, metal sieve with dry mint leaves, fresh mint leaves on the background of wooden boardsNervous system: In modern support of lemon balm’s traditional reputation, 55 sufferers from regular bouts of palpitation who took 14- day of treatment with 500 mg of lyophilized aqueous extract of lemon balm leaves, in comparison to the placebo reduced frequency of their palpitation episodes and significantly reduced anxiety (1). Two double-blind crossover studies evaluated the mood-affecting and cognitive effects of a standardised lemon balm preparation administered in a beverage and in yoghurt. In each study, a cohort of healthy young adults’ self-rated aspects of mood were measured before and after a multi-tasking framework administered one hour and three hours following one of four treatments. Both active lemon balm treatments were generally associated with improvements in mood and/or cognitive performance (2).

    In a double-blind, placebo-controlled, randomized, balanced crossover experiment, 18 healthy volunteers received two separate single doses of a standardized lemon balm extract (300 mg, 600 mg) and a placebo, on separate days separated by a 7-day washout period. 600 mg of lemon balm ameliorated the negative mood effects of a laboratory stress test, with significantly increased self-ratings of calmness and reduced self-ratings of alertness. In addition, a significant increase in the speed of mathematical processing, with no reduction in accuracy, was observed after ingestion of the 300-mg dose (3).

    In an earlier study 20 healthy, young participants received single doses of 600, 1000, and 1600 mg of dried lemon balm, or a matching placebo, at 7-day intervals. Cognitive performance and mood were assessed just before and up to 6 hours after, using an established computerised assessment battery and visual analogue scales. The most notable cognitive and mood effects were for the highest (1600 mg) dose: it improved memory performance and increased ‘calmness’ up to 6 hours after taking the herb. However, improved memory task performance and visual information- processing increased with decreasing dose (4).

    Inhaling the essential oil of lemon balm has also been shown to reduce agitation, in this case in a double blind controlled study among care home residents with severe dementia (5).

    In Germany, an analysis of compounds in lemon balm showed significant central nervous system calming activity. Germans made reference to psychological- autonomic imbalance, such as that which is produces symptoms of excitability, restlessness, headaches and palpitations; in a double blind clinical trial demonstrated a clear clinical improvement in participants symptoms (13).

    Cardiovascular system: In an other research direction, randomized, placebo-controlled trial with 62 patients received either 700 mg/day of lemon balm capsules or placebo for 12 weeks. Those taking the herb found significant differences in serum blood sugar, HbA1c, pancreatic β-cell activity lipid profile, inflammatory markers, and systolic blood pressure (6). The same team had earlier shown promising benefits on other markers of cardiovascular health relevant to the management of diabetes (7).

    Similar cardiovascular benefits were found among patients with chronic angina (8). 3 g daily over 8 weeks of lemon balm also reduced depression, anxiety, stress, and sleeplessness in this group of patients (9).

    Immune system: The reputation of concentrated lemon balm extracts in treating oral herpes simplex virus were tested in a double-blind, placebo-controlled, randomised trial with a standardised lemon balm cream (a dried 70:1 extract of lemon balm leaves) with 66 patients with at least four episodes per year or with placebo. The cream was applied to the affected area four times daily over five days. A combined symptom score of the values for complaints, at day 2 of therapy was formed as the primary target parameter. There was a significant difference in size of affected area and number of blisters in those taking the lemon balm (10).

    Pharmacology: Lemonbalm contains high quantities of rosmarinic acid, a compound also found in tulsi, sage and, of course, rosemary. This renowned chemical is thought to enhance the volume of the GABA neurotransmitter making it more bioavailable in the nervous system. It is thought to be the mechanism by which lemon balm induces feelings of calmness (12).

    Lemon balms bee-attracting essential oils, replicate the nasonov pheromone which is given off by bees to help orient the worker bees back to the colony. The oils have well-studied effects on the oral herpes virus. Some of these oils are geranial and neral, b-caryophyllene, linalool, geraniol, nerol, citronellal further contributing to the digestive and calming effects too (12).

    The monoterpenes in Lemonbalm have been found to have central nervous system calming effects. The volatile oils are responsible for the antiseptic activity (13).

  • Did you know?

    The volatile oils have been closely investigated in Germany where the plant is the main ingredient of a popular medicine known as ‘Melissengeist’.

Additional information

  • Botanical description

    Lemon balm is a member of the mint family native to Southern Europe, though now growing around the world. It will grow in natural wasteland at a range of different elevations and environmental conditions. The leaves produce a characteristically ‘lemony’ scent when rubbed. The plant can grow to a variety of heights, from just a few inches to a few meters, depending upon the space it has to spread. The leaves are petiolate, decussate, ovate, dentate, and arise from erect square stems, branching little at first, but much more at flowering. The small white flowers grow in cymes of 3-5 in the upper leaf axils: they are typically labiate ie. two-lipped, with 4 curved stamens and a 5-toothed calyx. The roots do not ‘creep’ in stolons like other mints.

  • Habitat

    Lemon balm is a member of the mint family native to Southern Europe, though now growing around the world. It will grow in natural wasteland at a range of different elevations and environmental conditions.

  • Sustainability

    Although classified as a protected species in Croatia, the International Union for Conservation of Nature (IUCN) European Red List of Medicinal Plants assigns M. officinalis to the conservation category of least concern, meaning that the species is not threatened in Europe. However, the situation is different in parts of Asia. In Iran, wild M. officinalis is reportedly threatened due to habitat destruction, land use changes, and overharvesting (15).

  • Quality control

    Melissa has tiny levels of essential oils (hence the expense), it loses much of its delightful smell on drying, and doesn’t fare much better as a tincture. Lemon balm is a herb that many herbalists can agree is best used fresh. Using fresh leaves picked from the garden for tea or tinctured from fresh in a good sweet brandy.

  • How to grow

    For best results, sow indoors in spring. Scatter the seeds on the surface (or carefully place in plug trays), cover with a very thin layer of soil and tamp down. It can take several weeks to germinate so be patient and keep the soil moist (12).

    Lemon balm is susceptible to frost damage, especially when young, so avoid planting out until you are confident that last frost has been and gone. Or – if you do plant out early – keep an eye on the weather forecast and cover the plants with fleece if there is a risk of overnight frost.

    Once established, lemonbalm may become prolific, so it is best kept in containers or small beds.

An ‘aromatic’ remedy, high in volatile essential oils, was most often associated with calming and sometimes ‘warming’ the digestion. Most kitchen spices and herbs have this quality: they were used both as flavouring and to ease the digestion of sometimes challenging pre-industrial foods. Many aromatics are classed as ‘carminatives’ and are used to reduce colic, bloating and agitated digestion. They also often feature in respiratory remedies for colds, chest and other airway infections. They are also classic calming inhalants and massage oils, and are the basis of aromatherapy for their mental benefits.
Astringent taste
The puckering taste you get with many plants (the most familiar is black tea after being stewed too long, or some red wines) is produced by complex polyphenols such as tannins. Tannins are used in concentrated form (eg from oak bark) to make leather from animal skins. The process of ‘tanning’ involves the coagulation of relatively fluid proteins in living tissues into tight clotted fibres (similar to the process of boiling an egg). Tannins in effect turn exposed surfaces on the body into leather. In the case of the lining of mouth and upper digestive tract this is only temporary as new mucosa are replenished, but in the meantime can calm inflamed or irritated surfaces. In the case of open wounds tannins can be a life-saver – when strong (as in the bark of broadleaved trees) they can seal a damaged surface. One group of tannins, the reddish-brown ‘condensed tannins’ are procyanidins, which can reduce inflammation and oxidative damage.
Bitters are a very complex group of phytochemicals that stimulate the bitter receptors in the mouth. They were some of the most valuable remedies in ancient medicine. They were experienced as stimulating appetite and switching on a wide range of key digestive functions, including increasing bile clearance from the liver (as bile is a key factor in bowel health this can be translated into improving bowel functions and the microbiome). Many of these reputations are being supported by new research on the role of bitter receptors in the mouth and elsewhere round the body. Bitters were also seen as ‘cooling’ reducing the intensity of some fevers and inflammatory diseases.
Blue-purple colouring
Any fruits with a blue-purple colouring contain high levels of the polyphenols known as anthocyanins. These work 1) on the walls of small blood vessels, helping to maintain capillary structure to reduce a key stage in inflammation, and improving the microcirculation to the tissues; 2) to improve retinal function and vision; 3) to support connective tissue repair around the body.
Traditional ‘cold’ or cooling’ remedies often contain bitter phytonutrients such a iridoids (gentian), sesiquterpenes (chamomile), anthraquinones (rhubarb root), mucilages (marshmallow), some alkaloids and flavonoids. They tend to influence the digestive system, liver and kidneys. Cooling herbs do just that; they diffuse, drain and clear heat from areas of inflammation, redness and irritation. Sweet, bitter and astringent herbs tend to be cooling.
Traditional ‘hot’ or ‘heating’ remedies, often containing spice ingredients like capsaicin, the gingerols (ginger), piperine (black or long pepper), curcumin (turmeric) or the sulfurous isothiocyanates from mustard, horseradich or wasabi, generate warmth when taken. In modern times this might translate as thermogenic and circulatory stimulant effects. There is evidence of improved tissue blood flow with such remedies: this would lead to a reduction in build-up of metabolites and tissue damage. Heating remedies were used to counter the impact of cold, reducing any symptoms made worse in the cold. .
Mucilages are complex carbohydrate based plant constituents with a slimy or ‘unctuous’ feel especially when chewed or macerated in water. Their effect is due simply to their physical coating exposed surfaces. From prehistory they were most often used as wound remedies for their soothing and healing effects on damaged tissues. Nowadays they are used more for these effects on the digestive lining, from the throat to the stomach, where they can relieve irritation and inflammation such as pharyngitis and gastritis. Some of the prominent mucilaginous remedies like slippery elm, aloe vera and the seaweeds can be used as physical buffers to reduce the harm and pain caused by reflux of excess stomach acid. Mucilages are also widely used to reduce dry coughing. Here the effect seems to be by reflex through embryonic nerve connections: reduced signals from the upper digestive wall appear to translate as reduced activity of airway muscles and increased activity of airway mucus cells. Some seed mucilages, such as in psyllium seed, flaxseed (linseed) or guar bean survive digestion to provide bulking laxative effects in the bowel. These can also reduce rate of absorption of sugar and cholesterol. .
New-mown hay aroma
The familiar country odour of haymaking, of drying grass and other plants, is largely produced by coumarins (originally isolated from tonka beans – in French coumarou) and widely used in perfumery. They are chemically categorised as benzopyrone lactones and are important phytochemicals, with strong antioxidant activity in the laboratory and likely effects in modulating inflammation. They were most often associated with the calming effect linked to their use in stuffing mattresses and pillows and plants, high In coumarins were commonly used for these properties.
Resins are most familiar as tacky discharges from pine trees (and as the substance in amber, and rosin for violin bows). They were most valued however as the basis of ancient commodities like frankincense and myrrh (two of the three gifts of the Three Wise Men to the baby Jesus) and getting access to their source was one benefit to Solomon for marrying the Queen of Sheba (now Ethiopia). Resins were the original antiseptic remedies, ground and applied as powders or pastes to wounds or inflamed tissues, and were also used for mummification. With alcohol distillation it was found that they could be dissolved in 90% alcohol and in this form they remain a most powerful mouthwash and gargle, for infected sore throats and gum disease. They never attracted much early research interest because they permanently coat expensive glassware! For use in the mouth, gums and throat hey are best combined with concentrated licorice extracts to keep the resins in suspension and add extra soothing properties. It appears that they work both as local antiseptics and by stimulating white blood cell activity under the mucosal surface. They feel extremely effective!
The salty flavour is immediately distinctive. A grain dropped onto the tongue is instantly moistening and a sprinkle on food enkindles digestion. This easily recognisable flavour has its receptors right at the front of the tongue. The salty flavor creates moisture and heat, a sinking and heavy effect which is very grounding for the nervous system and encourages stability. People who are solid and reliable become known as ‘the salt of the earth'.
The sharp taste of some fruits, and almost all unripe fruits, as well as vinegar and fermented foods, is produced by weak acids (the taste is generated by H+ ions from acids stimulating the sour taste buds). Sour taste buds are hard-wired to generate immediate reflex responses elsewhere in the body. Anyone who likes the refreshing taste of lemon or other citrus in the morning will know that one reflex effect is increased saliva production. Other effects are subjective rather than confirmed by research but there is a consistent view that they include increased digestive activity and contraction of the gallbladder.
In the days when most people never tasted sugar, ‘sweetness’ was associated with the taste of basic foods: that of cooked vegetables, cereals and meat. In other words sweet was the quality of nourishment, and ‘tonic’ remedies. Describing a remedy as sweet generally led to that remedy being used in convalescence or recovery from illness. Interestingly, the plant constituents most often found in classic tonics like licorice, ginseng are plant steroids including saponins, which also have a sweet taste.
