[span class=alert]This section is a list of chemical entities identified in this dietary supplement to possess pharmacological activity. This list does not imply that other, yet unidentified, constituents do not influence the pharmacological activity of this dietary supplement nor does it imply that any one constituent possesses greater influence on the overall pharmacological effect of this dietary supplement.[/span]


Melissa, or lemon balm, is a member of the Lamiaceae family, which includes thyme (Thymus vulgaris), mint (Mentha sp.) and rosemary (Rosmarinus officinalis). Melissa is commonly used in Europe as a tea, liquid extract, and a topical preparation. Traditionally, melissa preparations were used as a carminative, diaphoretic, febrifuge, and as a calming agent for children. Ancient Greeks and Romans used melissa in surgical dressings for wounds and in preparations to treat venomous bites and stings such as with dogs and scorpions, as described in the writings of Dioscorides and Pliny the Elder. Old European medicinal herbal texts list melissa as an agent for memory-improvement, which was recently supported by the findings that melissa reportedly has cholinergic activity.(3),(4),(5)

Toxicities & Precautions


Melissa has been reported safe in recommended dosages.

If used topically and condition worsens or does not improve in 7 days, consult a physician.



There have been several reports of melissa topical extract (70:1w/v) being useful in the treatment of herpes labialis.(6),(7),(8),(9) A double-blind, placebo-controlled, randomized trial was carried out with the aim of proving the efficacy of standardized melissa cream for the therapy of herpes simplex labialis.(10) In addition to shortening the healing period, melissa extract aided in the prevention of spreading the infection and had an effect on typical symptoms of herpes like itching, tingling, burning, stabbing, swelling, tautness, and erythema. The authors concluded that the different mechanism of antiviral action of melissa extract rules out the development of resistance of the herpes virus. Some indication exists that the intervals between periods with herpes might be prolonged with melissa cream treatment. Another study reported virucidal and antiviral effects of melissa extracts with respect to Herpes simplex virus type 1 (HSV-1).(11) Of interest is that melissa has also been reported to have anti-HIV-1 activity in vitro.(12),(20)


Melissa traditionally has been used as a nervine, or agent that supports the nervous system and aids in decreasing stress along with improving sleep.(16) The German Commission E approves the internal use of melissa for nervous sleeping disorders and functional gastrointestinal complaints.(17) Mechanism of anti-anxiety activity includes binding to GABA receptors.(21)

Several human studies report that combinations of Melissa and other sedating herbs (such as valerian and hops) are effective in decreasing stress and anxiety in children and adults.(22)

Other Uses

Melissa is traditionally used to support cognitive function. Laboratory and human studies support this use, with acute administration of Melissa being found to improve memory performance in healthy young and elderly cohorts and also decreasing cognitive decline in individuals with Alzheimer's disease.(23) Melissa has been reported to bind directly to both nicotinic and muscarinic receptors in human brain tissue.(24)

The constituent rosmarinic acid (also found in oregano and other herbs such as Holy basil and rosemary) has been reported in vitro to have cyclooxygenase 2 (COX-2) inhibiting properties comparable to ibuprofen, naproxen, and aspirin at 10-, 100-, and 1000-microM concentrations, respectively.(18)

Melissa also has reported antibacterial and antifungal activity in vitro.(13) Melissa was reported to have antioxidant effects in vitro, most likely based on flavonoid content (rosmarinic acid).(14),(15)

Freeze-dried extracts (FDE) of melissa as well as products of the oxidation of certain of its constituents, have been reported to exert antithyrotropic activity in laboratory animals.(19) The authors suggest that the active principles in those FDE and their oxidized constituents with antithyrotropic activity could potentially interact with the pathogenically important components of Graves-IgG to inhibit their ability to bind to the TSH receptor and activate the thyroid, as they do with TSH.
