Overview

Lemon balm (Melissa officinalis), a member of the mint family, has long been considered a "calming" herb. It has been used since the Middle Ages to reduce stress and anxiety, promote sleep, improve appetite, and ease pain and discomfort associated with digestion (including flatulence and bloating as well as colic). Even before the Middle Ages, lemon balm was steeped in wine to lift the spirits, help heal wounds, and treat venomous insect bites and stings. Today, lemon balm is often combined with other calming, soothing herbs, such as valerian, to enhance the overall relaxing effect.

Lemon Balm for Anxiety and Insomnia
Several studies have found that lemon balm combined with other calming herbs (such as valerian) helps reduce anxiety and promote sleep. Few studies have investigated the safety and effectiveness of oral lemon balm alone, however. For example, in one recent study of people with minor sleep disorders, those who ingested an herbal combination of valerian and lemon balm reported sleeping much better than those who ingested placebo pills. It is not clear from these studies, however, whether lemon balm itself (or the combined action of lemon balm and valerian) is responsible for these sleep-inducing effects.

Herpes
Some studies suggest that topical ointments containing lemon balm may help heal lip sores associated with herpes simplex virus (HSV). In one study of 116 people with HSV, those who applied lemon balm cream to their lip sores experienced significant improvement in redness and swelling after only two days. Although other symptoms, (such as pain and scabbing) did not improve, both the patients and their physicians reported that the lemon balm ointment was highly effective. Several animal studies also support the value of topical lemon balm for herpes lesions.

Other including Lemon Balm for ADHD
Although few rigorous scientific studies have been conducted on lemon balm, many professional herbalists suggest that this herb is beneficial for a variety of health problems including Alzheimer's disease, attention deficit/hyperactivity disorder (ADHD), indigestion, insomnia, and hyperthyroidism. Experimental laboratory studies also suggest that lemon balm has antioxidant and anti-HIV properties, but further studies are needed to confirm these findings.

Plant Description

Lemon balm is native to Europe but is now grown all over the world. It is grown not only in herb gardens, but also in crops for medicine, cosmetics, and furniture polish manufacturing. The plant grows up to two feet in height, sometimes higher if left not maintained. In the spring and summer, clusters of small, light yellow flowers grow where the leaves meet the stem. The leaves are very deeply wrinkled and range from dark green to yellowish green in color, depending on the soil and climate. If you rub your fingers on them, your fingers will smell tart and sweet, like lemons. The leaves are similar in shape to mint leaves, and in fact, come from the same plant family.

What's It Made Of?

Lemon balm preparations are made from the leaves of the plant. Essential oils made from lemon balm leaves contain plant chemicals called terpenes, which play at least some role in the herb's relaxing and antiviral effects. Lemon balm also contains substances called tannins, which are thought to cause many of the herb's antiviral effects. Lemon balm also contains eugenol, which calms muscle spasms, numbs tissues, and kills bacteria.

Available Forms

Lemon balm is available as a dried leaf that can be bought in bulk. It is also sold as tea, and in capsules, extracts, tinctures, and oil. The creams used in Europe, which contain high levels of lemon balm, are not currently available in the United States. On the other hand, teas can be applied to the skin with cotton balls.

How to Take It

Pediatric

Lemon balm may be used topically in children to treat cold sores. The dosage would be the same as the recommendations for use in adults.

For internal use, adjust the recommended adult dose to account for the child's weight. Most herbal dosages for adults are calculated on the basis of a 150 lb (70 kg) adult. Therefore, if the child weighs 50 lb (20 to 25 kg), the appropriate dose of lemon balm for this child would be 1/3 of the adult dosage.

Adult

For difficulty sleeping, or to reduce stomach complaints, flatulence, or bloating, choose from the following:

• Tea: 1.5 to 4.5 grams of lemon balm herb, several times daily
• Tincture: 2 to 3 mL (40 to 90 drops), 3 times daily, or the equivalent in fluid extract or encapsulated form

For cold sores or herpes sores, steep 2 to 4 tsp of crushed leaf in 1 cup boiling water for 10 to 15 minutes. Cool. Apply tea with cotton balls to the sores throughout the day.

Precautions

The use of herbs is a time-honored approach to strengthening the body and treating disease. Herbs, however, contain active substances that can trigger side effects and interact with other herbs, supplements, or medications. For these reasons, herbs should be taken with care, under the supervision of a practitioner knowledgeable in the field of botanical medicine.

No side effects or symptoms of toxicity have been reported with lemon balm use, but this herb should not be used by pregnant or breastfeeding women.

Possible Interactions

Sedatives, Thyroid medications
Although it has not yet been demonstrated in clinical studies, lemon balm may interfere with sedatives and thyroid medications. If you are taking sedatives (for sleep disorders or anxiety) or medications to regulate your thyroid, you should consult a healthcare practitioner before taking lemon balm.
