Commonly called by its Latin first name, Melissa, lemon balm is a native of southern Europe, often planted in gardens to attract bees. Its leaves give off a delicate lemon odor when bruised.

Medical authorities of ancient Greece and Rome mentioned topical lemon balm as a treatment for wounds. The herb was, and in some cases still is, used orally as a treatment for generalized anxiety, influenza, insomnia, depression, panic disorder and nervous stomach.

Effect of Lemon Balm on Generalized Anxiety Disorder

Though the exact reasons are unknown, lemon balm (Melissa) has been show to have anti-anxiety affects in addition to its antiviral and antidepressant properties as well.

Research Evidence on Lemon Balm

Several small double-blind studies by a single research group have found preliminary evidence that oral use of lemon balm (Melissa officinalis) may reduce anxiety levels.46,47 Like other anti-anxiety agents, it may also impair mental function to some degree. A combination of lemon balm and valerian has also been tested, with generally positive results.48

Side Effects and Warnings

#Safety Issues

Topical lemon balm is not associated with any significant side effects, although allergic reactions are always possible. Oral lemon balm is on the FDA's GRAS (generally recognized as safe) list. However, according to one study, lemon balm reduces alertness and impairs mental function; for this reason, individuals engaging in activities that require alertness, such as operating a motor vehicle, should avoid using lemon balm beforehand. ^[1] In addition, one animal study suggests that if lemon balm is taken at the same time as standard sedative drugs, excessive sedation might occur. ^[2]

#Interactions You Should Know About

If you are taking sedative medications, use of oral lemon balm might amplify the effect, potentially leading to excessive sedation.
