Herbal Focus: Lemon Balm

Article and photos copyright Debs Cook
Lemon Balm (Melissa officinalis) is an herbaceous perennial that grows to a height of between 60-90cm, it is a native herb of Europe, western Asia and northern Africa, but can be found growing all across the world. Its broad, aromatic lush, bright green, heart shaped leaves are slightly hairy with a toothed edge and crinkly texture, and grow either side of the square stem. The square stems serve as a reminder that Lemon balm is a relative of the mint family and needs treating in much the same way as mint to prevent the plant taking over the garden. The 2-lipped flowers are rather inconsequential, small and white growing in whorled clusters along the stem close to the leaf axils.

It has been grown as a medicinal plant for well over 2,000 years, the ancient Greeks dedicated it to the Goddess Diana and gave it the name Melissa officinalis, ’Melissa’ being a Latin derivation of the Greek word for honey bee; and ‘officinalis’ indicates that the plant had a medicinal nature. Other names for Lemon Balm include: - Bawme, Bee Balm, Dropsy Plant, Mélisse, Zitronenmelisse, Cedronella, Erba cedratra, Baklut-ul-Faritstum, Badaranj and Badrunj Buyeh.

Lemon balm has had a variety of uses over the centuries including helping wounds to heal, treating venomous insect bites and stings, settling the digestion, relieving headaches and easing toothaches. It has Anti-anxiety, Antibacterial, Anti-depressant, Antiemetic, Anti-fungal, Antispasmodic, Antiviral, Aromatic, Carminative, Diaphoretic, Digestive, Emmenagogue, Febrifuge, Sedative and Tonic properties.

Pliny the Elder in the 1st century A.D. valued Lemon Balm as a styptic herb writing that ‘It is of so great virtue that though it be but tied to his sword that hath given the wound it stauncheth the blood’. The ancient Greeks used it as both a medicine and a culinary ingredient, and believed that planting lemon balm around their bee hives was a good way to encourage bees to frequent the hives.

In 9th century Europe, Emperor Charlemagne was so impressed with the healing properties of lemon balm that he ordered that it should be grown not just in his apothecary gardens, but in every monastic garden in his empire. Avicenna, the renowned 10th century Arabian physician wrote of the cordial and uplifting benefits of Lemon Balm saying that it “causeth the mind and heart to be merry.” The herb was used by the Persians to treat heart conditions, aid the memory and to lift depression.

In the Middle-Ages, it was used to help wounds to heal, to ease the digestion and as a way to relieve anxiety, as such, it was steeped in wine to help lift depression, and was first mentioned medicinally for this used in European herbals as Herbe Melisse around the early 15th century.

Examples of this cordial remedy for the spirits can be found in The London Dispensary published in 1696, their entry for Lemon Balm states 'An essence of Balm, given in Canary wine, every morning will renew youth, strengthen the brain, relieve languishing nature and prevent baldness.' The herb was popular in 17th century France in the form of Carmelite Water also known as ‘Eau de Melisse’. As well as lemon balm this aromatic remedy contained fourteen herbs and spices including sage, coriander, angelica, chamomile and yellow gentian all distilled in alcohol. Cardinal Richelieu is said to have taken it regularly for his migraines, and the ladies of the court of Louis XIV carried it with them everywhere to help with ease stomach aches, digestive troubles, shocks, nerves, and sudden cold. Today it is still one of the ingredients found in the French herbal liqueurs Benedictine and Chartreuse, as well as many other liqueurs, cordials and digestive drinks.

Hilda Leyel (1880-1957), founder of the Society of Herbalists included a recipe for a ‘Compound Spirit of Balm’ in her book ‘Herbal Delights’, Faber & Faber Limited, 1937 which she said had a cordial and balsamic effect on the heart. ‘Take of the fresh leaves of balm, 8 ounces; lemon peel bruised, 4 ounces; nutmegs and caraway seeds, of each, 2 ounces; cloves, cinnamon and angelica root, of each, 1 ounce. Distil all together with a quart of brandy. It must be well preserved in bottles with ground glass stoppers.

A variety of 17th century writers and herbalists praised the properties of Lemon Balm, John Evelyn, English writer and author of ‘Acetaria: A Discourse of Sallets’ first published in 1699, wrote that ‘Balm is sovereign for the brain, strengthening the memory and powerfully chasing away melancholy’. John Gerard in his herbal wrote 'the juice of Balm glueth together greene wounds’ and Nicholas Culpeper recommended that women should drink the syrup ‘to relieve the weak stomachs and sick bodies’, echoing its use as a soothing and nourishing tonic.

The 20th century physician and writer Dr W. T. Fernie wrote ‘Tea made of our garden balm, by virtue of the volatile oil, will prove restorative, and will promote perspiration if taken hot on the access of a cold or of influenza; also, if used in like manner, it will help effectively to bring on the delayed monthly flow with women. But an infusion of the plant made with cold water, acts better as a remedy for hysterical headache, and as a general nervine stimulant because the volatile aromatic virtues are not dispelled by heat.

Into the 21st century the popularity of this herb as a medicinal and culinary ingredient continues, in 2007 the American Herb Society celebrated the herb making it their herb of the year and in Europe clinical studies are being carried out as to the effects that lemon balm can have on Alzheimer’s disease and dementia.

Making Use of Lemon Balm



I use lemon balm for making cakes, salad dressings and adding to stuffing, I also make tinctures, and soothing teas and cold sore salves (see recipe below), as a tea it’s good for mild cases of indigestion when I want something different to peppermint, and a warm infusion of lemon balm is brilliant at easing toothache, it contains eugenol the compound found in Cloves which helps to calm muscles and soothe tissues.

Lemon balm tea is a soothing caffeine free tea substitute that has a pleasant, sweetly, mild minty, citrus flavour and a delightful aroma, ideal as a pre bedtime drink. To make a mug of lemon balm tea add 1-2g of dried lemon balm tea to a teapot or infuser (or use 1-2 tablespoons of fresh) - depending on how strong you like your tea – and pour over enough fresh boiling water as required. Strain into a mug, sweeten with preferred sweetener e.g. honey and serve. Serve without milk, lemon balm tea can also be served chilled like ice tea.

In the kitchen lemon balm works well with sweet and savoury dishes, use it to make herbal vinegar, or why not add the fresh leaves to a homemade strawberry cheesecake? You can also make and excellent pesto with it nut mixing 125ml extra virgin olive oil, 3 crushed garlic cloves, a little freshly ground black pepper and 1 handful (or two) of fresh lemon balm and blitz in a blender to combine, its is superb served alongside pasta, fish or chicken. Lemon Balm leaf can also be added to scented sachets and pot pourri to help deter moths.

Lemon Balm Tincture can be dabbed on to insect bites and cold sores and added to soaps, creams, lotions, balms and salves for the skin where anti-viral and anti-bacterial properties are required, it can also be added to shampoos, and bath/shower preparations. A decoction of lemon balm can be added to lotions, shampoos, creams and soaps for the skin and hair. Dried lemon balm has insect repellent properties and can be added to sachets to help deter moths and flying insects. It can also be drunk as a soothing tisane and digestive, powdered it can be added to foot powders for athlete’s foot.

Did you know that the oil extracted from Melissa is often mixed with other citrus oils to make creams and sprays for deterring insects such as mosquitoes? The oil contains citronellal a monoterpenoid that gives citronella oil its lemony scent. Citronellal is a natural plant-based insect repellent which also has anti-fungal properties, the chemical is also found in lemongrass, lemon eucalyptus and kaffir lime leaves.

Possible Interactions


A few years ago someone told me that I shouldn't partake of Lemon Balm because I have an Under-active Thyroid condition. I asked where the person telling me that Lemon Balm wasn't safe for my condition had got their information and they didn't know, they'd just been told by someone. I finally tracked the info down to a report done by the University of Maryland where they state under their ’Possible Interactions with: Lemon Balm’ entry that: -

"Sedatives, thyroid medications. Although there is no scientific evidence of this, Lemon Balm may interact with sedatives and thyroid medications. If you are taking sedatives (for insomnia or anxiety) or medications to regulate your thyroid, ask your doctor before taking Lemon Balm".

Lemon Balm Cold Sore Salve


When I get stressed I sometimes suffer from cold sores, I get them about twice a year now, but as a teenager it used to be 6-8 times a year. I originally found a recipe in James Wong’s Grow Your Own Drugs book, his recipe contained Lemon Balm, Wheatgerm Oil (as a preservative), Olive Oil, Honey, Beeswax and Tea Tree Oil, but I wanted to have a more potent Cold Sore Salve to hand.

I did some research and discovered that Lavender oil can be used for cold sores and St John’s Wort can help sooth nerve pain, so adding that to a salve would be a useful addition for treating cold sores when they're just starting and when they're at their painful stage. Olive Oil acts as a moisturiser which is good when the skin starts to crack and when the 'blister' is drying out to help the skin cells regenerate.

Lemon Balm has brilliant anti-viral and anti-bacterial qualities and is well known for being a useful herb for treating the Herpes Simplex (Cold Sore) virus. The honey is wonderfully moisturising and anti-bacterial to boot, the tea tree oil has anti-viral properties and it's incredibly healing.

Ingredients:

21g Dried Lemon Balm
3 Tbsp. Wheatgerm Oil
65ml St John's Wort Infused Oil
50ml Extra Virgin Olive Oil
1 Tbsp. Manuka Honey
1 Tbsp. Beeswax
3 Drops Melissa Essential Oil
3 Drops Lavender Essential Oil
2 Drops Tea Tree Essential Oil

Method: First split the dried lemon balm in to 3 x 7g portions, then using a double boiler add 7g of the Lemon Balm along with the Wheatgerm and St John’s Wort oils to the top pan and let it heat gently for 10 minutes, or until it starts to bubble. Once it does, take it off the heat and allow to cool.

Strain the Lemon Balm infused oil through a muslin-lined sieve or colander into a bowl, make sure you squeeze all the infused oil out. Discard the spent Lemon Balm.

Repeat this process two more times using the remaining 2 x 7g portions of Lemon Balm in the oil you've already infused.

Once you've infused all the Lemon Balm in the oil put the pan back on top of your double boiler and heat it up gently, whilst still warm add the Manuka honey, beeswax and the essential oils and stir together well.

Pour your Lemon Balm Salve into small sterilised jars; it will set in around 10-15 minutes depending on the room temperature. Use the salve at the first sign of a cold sore when you start to get that 'tingly' feeling and during the period that the cold sore lasts for. The Salve will keep for up to 1 year.

N.B. Use pure Vitamin E or Olive oil if you have an allergy to Wheat.
