What Are Star Ratings?
Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
3 Stars Reliable and relatively consistent scientific data showing a substantial health benefit.
2 Stars Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
1 Star For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
This supplement has been used in connection with the following health conditions:
Traditional Use (May Not Be Supported by Scientific Studies)
Charlemagne once ordered lemon balm planted in every monastery garden because of its beauty.1 It has been used traditionally by herbalists to treat gas, sleeping difficulties, and heart problems. In addition, topical applications to the temples were sometimes used by herbalists for insomnia or nerve pain.
How It Works
How It Works
The terpenes, part of the pleasant smelling volatile oil from lemon balm, are thought to produce this herb’s relaxing and gas-relieving (carminative) effects. Flavonoids , phenolic acids, and other compounds appear to be responsible for lemon balm’s anti-herpes and thyroid-regulating actions. Test tube studies have found that lemon balm blocks attachment of antibodies to the thyroid cells that cause Grave’s disease (hyperthyroidism).13 The brain’s signal to the thyroid (thyroid-stimulating hormone or TSH) is also blocked from further stimulating the excessively active thyroid gland in this disease. However, clinical trials proving lemon balm’s effectiveness in treating Grave’s disease are lacking.
One small preliminary trial studying sleep quality compared the effect of a combination product containing an extract of lemon balm (Melissa officinalis) and an extract of valerian root with that of the sleeping drug triazolam (Halcion). The effectiveness of the herbal combination was similar to that of Halcion, as determined by the ability to fall asleep and the quality of sleep.14 Another trial also found that the same combination of valerian and lemon balm, taken over a two-week period, is effective in improving quality of sleep.15
According to double-blind research, topical use of a concentrated lemon balm extract speeds healing time of herpes simplex virus sores ( cold sores ) on the mouth.16 , 17
How to Use It
The German Commission E monograph suggests 1.5 to 4.5 grams of lemon balm in a tea several times daily.18 The herb can be steeped for ten to fifteen minutes in 150 ml of boiling water to make the tea. Tincture can also be used at 2 to 3 ml three times per day. Concentrated extracts, 160 to 200 mg 30 minutes to one hour before bed, are sometimes recommended for insomnia . Highly concentrated topical extract ointments for herpes can be applied three to four times per day to lesions.
Lemon balm is frequently combined with other medicinal plants. For example, peppermint and lemon balm together are effective for calming upset stomach . Valerian is often combined with lemon balm for insomnia. Bugleweed (Lycopus virginicus) and lemon balm have been used together for Graves’ disease.
