Lemon balm (Melissa officinalis) is best known as a calming herb, traditionally used in teas and supplements to support relaxation and restful sleep. Yet this fragrant, lemon-scented plant offers benefits extending far beyond its soothing properties. Cultivated on a significant scale for pharmaceutical and cosmetic industries, lemon balm represents one of the most versatile herbs in traditional European herbalism.
Composition and Properties
Lemon balm is valued in both pharmaceutical and cosmetic applications. The pharmaceutical industry primarily uses the herb (aerial parts), while leaves form the basis of calming herbal teas.
For optimal potency, both herb and leaves should be harvested at the beginning of flowering, when beneficial compound concentrations peak.
The characteristic lemon aroma comes from the essential oil, which contains geranial, citral, geraniol, linalool, and citronellal. The herb also contains phenolic acids (chlorogenic, rosmarinic, caffeic, and ferulic acids), triterpenes (oleanolic and ursolic acids), and flavonoids (luteolin, quercetin, kaempferol, apigenin).
Additionally, lemon balm provides vitamin C and mineral salts. This rich composition makes it valuable for both calming support and general wellness.
Topical Applications
Several compounds in lemon balm have been studied for antimicrobial properties. Tannins and phenolic acids show activity in laboratory research, leading to lemon balm's inclusion in various topical preparations.
Lemon balm-based ointments and creams are available for skin comfort. The essential oil can be applied topically but may cause sensitivity in some individuals, potentially causing redness or itching. Patch testing before broader use is advisable.
Lemon balm infusions have been traditionally used as mouth rinses for oral comfort, supporting gum health and freshening breath.
For insect bites and stings, lemon balm oil applied to a cool compress may help soothe the affected area, providing comfort and supporting the skin's natural response.
Relaxation and Sleep Support
Lemon balm's most celebrated application is for relaxation and sleep support. Available as dried herb for infusions and as liquid concentrates, it has been traditionally used during periods of nervous tension, stress, or restlessness.
The herb supports relaxation and may help ease the transition to sleep. Traditional use includes support during times of low mood or nervous tension.
Quality consideration: Commercially available dried lemon balm varies considerably in quality. Products lacking essential oil content may be less effective. Concentrated extracts or home-grown lemon balm often provide better results than low-quality dried preparations.
The calming properties extend to supporting comfortable feelings in the chest area during stress and may help ease tension-related head discomfort.
Digestive Support
Lemon balm infusions have a long tradition of use for digestive comfort. The herb may support digestive secretions, helping promote comfortable digestion and appetite.
A cup of lemon balm tea after a heavy meal is a traditional approach to digestive comfort. The herb has relaxing properties that may help ease occasional digestive tension and discomfort.
Traditional use also includes support for liver and gallbladder comfort, contributing to the herb's reputation as a gentle digestive aid.
Cognitive Support
Less widely known is lemon balm's traditional use for cognitive function. Research has explored the herb's potential to support memory and concentration.
Some studies have investigated lemon balm's effects on cognitive function, with promising results regarding mental clarity and focus. Regular consumption of lemon balm tea has been associated with cognitive wellness in traditional use.
Women's Wellness
Traditional herbalism includes lemon balm among herbs used for women's comfort during the menstrual cycle. The herb's relaxing properties may help ease monthly discomfort and support overall wellbeing during this time.
Available Forms
Lemon balm supplements and preparations come in various formats:
Dried herb for preparing infusions remains the most traditional method. Quality varies significantly; look for aromatic products with visible essential oil presence.
Liquid concentrates and tinctures offer more consistent potency than variable-quality dried herbs. These are easily absorbed and convenient to use.
Capsules and tablets containing lemon balm extract provide standardised dosing and suit those who prefer not to prepare teas.
Essential oil is used topically (always diluted) or in aromatherapy. It should not be consumed orally without professional guidance.
Combination products often pair lemon balm with other calming herbs like valerian, passionflower, or chamomile for enhanced relaxation support.
Safety and Considerations
Lemon balm is generally considered safe with a long history of traditional use. However, some considerations apply.
Pregnancy and breastfeeding: Opinions vary on lemon balm use during pregnancy. Some sources advise caution, suggesting the herb might affect uterine activity. During breastfeeding, lemon balm compounds may pass into milk. Notably, many children's calming teas include lemon balm, suggesting general safety, but pregnant and nursing women should consult healthcare providers.
Allergic reactions: While rare with internal use, allergic reactions are more common with topical application of essential oil. If sensitivity occurs, discontinue use.
Medication interactions: Those taking sedative medications or thyroid medications should consult healthcare providers before using concentrated lemon balm preparations.
Quality matters: Low-quality dried lemon balm lacking essential oils may provide little benefit. Choosing quality preparations ensures meaningful support.
No significant side effects have been documented from traditional tea consumption at normal amounts. The herb's safety profile contributes to its widespread use in calming preparations.
