The Medicinal Benefits of Lemon Balm

In this book excerpt, you’ll learn about the medicinal benefits of lemon balm, how to grow it, and its culinary uses. The healing benefits of lemon balm are legendary: it has a long history of use as a digestive and nervous system remedy. With its citrusy aroma and quilted lime-green leaves, lemon balm (Melissa officinalis) brightens our gardens and kitchens alike. This mint family medicinal is known as the “gladdening herb” for the uplifting qualities it brings to the spirit. The medicinal benefits of lemon balm as a relaxing remedy and pleasant tea are evident in the tea bag aisle of natural grocers.

The medicinal properties of lemon balm go back so far; these early uses are embedded in its name. The origin of the word balm is similarly telling: it is derived from balsam, a plant or application with healing or restorative qualities. The medicinal benefits of lemon balm have long been thought to impart vitality and bestow longevity. The Swiss alchemist Paracelsus called the herb “the elixir of life.” Children have a particular fondness for its sunny aroma and sour flavor. Bees are equally fond of the herb—so much so that the Greek word for bee, melissa, is another name for the plant.

The following article is a sneak peek excerpt from my debut book, The Healing Garden: Cultivating and Handcrafting Herbal Remedies. This book is a detailed herbal reference, decadent cookbook, and garden manual all in one. It is written for home gardeners and anyone looking to bring the therapeutic benefits of healing herbs into their garden, kitchen, and apothecary. You can purchase a copy wherever books are sold. You can find more details on the book and its accompanying bonuses here.

Medicinal Uses of Lemon Balm

Part Used: Leaves and flowering tops

Medicinal Preparations: Infusion, tincture, vinegar, honey, oxymel, infused oil, salve, pesto, finishing salts, compound butter, and condiment

Actions: Nervine, hypnotic, carminative, antiviral, antibacterial, antianxiety, antidepressant, antioxidant, and diaphoretic

Energetics: Cooling and slightly drying

Lemon balm is both soothing and uplifting. The tea is the best form for lemon balm’s medicinal benefits, specifically its nervine qualities, as the herb’s essential oils gently waft over the imbiber from the teacup. It is a gentle sedative, on par with mint (Mentha spp.), linden (Tilia spp.), and chamomile (Matricaria recutita), and safe for children or those with chronic illness. Lemon balm assuages tension headaches, anxiety, insomnia, restlessness, and panic attacks. Combine it with milky oats (Avena sativa), ashwagandha (Withania somnifera), and skullcap (Scutellaria lateriflora) as a tonic herb for stress.

As a carminative, lemon balm soothes intestinal gas and bloating, especially when stress-related. Fennel (Foeniculum vulgare), mint (Mentha spp.), and catnip (Nepeta cataria) are all fine companions for lemon balm in a digestive tea suitable for all ages. When breastfeeding, you can sip on the tea to help calm restless babies and mollify colic: the herb’s healing qualities pass into breast milk.

Lemon balm and lavender (Lavandula angustifolia) both play a starring role in the centuries-old herbal toner known as Queen of Hungary’s Water. This garden cosmetic also features rose (Rosa spp.), calendula (Calendula officinalis), rosemary (Salvia rosmarinus), sage (Salvia officinalis), elderflower (Sambucus nigra var. canadensis), and comfrey (Symphytum officinale) infused in a base of vinegar or witch hazel (Hamamelis virginiana) extract. Lemon balm lends its topical medicinal uses as an antioxidant and antimicrobial to this formula. The fragrant elixir is an antioxidant and astringent toner—it is said to have kept the queen looking so sprightly that she attracted the attention of a suitor nearly 50 years her junior.

Precautions : Lemon balm may lower thyroid levels; consult a medical practitioner and use cautiously in hypothyroidism and with thyroid hormone replacement.

Culinary Uses of Lemon Balm

Lemon balm leaves have a sour and aromatic minty flavor. Like citrus, lemon balm comfortably saddles up to sweet and savory dishes alike. Add the tender fresh leaves to finishing salts, herbal vinegars, compound butters, salsas, and pestos (see my recipe here); or mince the leaves and add them to fruit salad, jam, cookies, scones, whipped cream, sorbet, or ice cream. In the summertime, add a few sprigs to a pitcher of water or a carafe of white wine and let infuse for one to two hours before enjoying.

How to Grow and Harvest Lemon Balm

ZONES: 4–10; full sun to partial shade

SOIL: pH 5–7.5; fertile soils with good drainage

SIZE: 1–2 feet tall; 1–2 feet wide

LIFESTYLE: Herbaceous perennial

It is scandalous to imagine an herb garden without lemon balm, considering its amicability and medicinal and culinary versatility. Cut back the flowering stems before they set seed, or the plant will self-sow and become weedy. Mulch to keep dirt from splashing up on the leaves and spreading soil-borne diseases.

If you live in a hot and humid climate, plant the herb in partial shade, and it will reward you with larger, more luscious leaves. If you live in a cooler region, lemon balm will grow buoyantly in full sun—its leaves may be smaller, but it will be highly aromatic. In the northern reaches of lemon balm’s range, wet soils can kill the plants over the winter. Be sure to create ample drainage to prevent this.

You can obtain several harvests by giving the plants a periodic haircut, leaving 6 inches of growth intact. Be careful not to pile up the harvest, as lemon balm is prone to oxidation and can turn an unsavory brown color. Hang in bundles or dry on screens. Lemon balm doesn’t keep as long as other dried herbs. Let its aroma guide you in determining when your stored lemon balm is no longer potent. For culinary use, such as pesto, the tender new growth in the spring is ideal.
