Lemon balm (Melissa officinalis) is an herb often used to treat anxiety and stress. A member of the mint family, lemon balm contains terpenes (chemicals thought to produce a relaxing effect).
Uses for Lemon Balm
Common health claims for lemon balm include the treatment and/or prevention of these conditions:
Benefits of Lemon Balm
To date, few scientific studies have focused on the health effects of lemon balm. However, findings from available research suggest that the herb shows promise in treatment of the following:
1) Cold Sores
Shown to possess antiviral properties, lemon balm has been found to promote the healing of cold sores (small, painful blisters caused by the herpes simplex virus-1) in several studies. In treatment of cold sores, lemon balm is typically applied topically (in the form of a cream or ointment).
Preliminary research indicates that topical application of lemon balm may also be useful in treatment of genital herpes (a condition caused by the herpes simplex virus-2).
2) Alzheimer's Disease
Lemon balm may benefit people with Alzheimer's disease, according to a 2003 study. For four months, 42 older adults with mild to moderate Alzheimer's disease took a daily dose of lemon balm or a placebo. At the end of the treatment period, those taking lemon balm showed a significantly better outcome on cognitive function. In addition, agitation (a problem prevalent among Alzheimer's patients) was found to be less common in the lemon balm group.
In a 2006 study of 24 healthy volunteers, scientists discovered that taking a combination of lemon balm and valerian helped reduce participants' anxiety levels during a stress-inducing lab experiment.
In a research review published in 2005, investigators found that lemon balm "may have some effect on sleep" but cautioned that "reports are too scanty to form any opinion about this."

How to Use Lemon Balm
Although lemon balm is generally considered safe, the herb may interact with sedatives and thyroid medications.
Given the lack of scientific support for lemon balm's health effects, it's important to consult your physician before using this herb in treatment of any health condition.
Lemon Balm Tea
Available in capsule and tincture form, lemon balm can also be consumed as a tea. When brewing lemon balm tea, make sure to keep the teapot or cup covered at all times in order to hold in the steam (thought to contain the herb's therapeutic aromatic oils).
