LEMON BALM Overview Information
Lemon balm is a perennial herb from the mint family. The leaves, which have a mild lemon aroma, are used to make medicine. Lemon balm is used alone or as part of various multi-herb combination products.
Lemon balm is used for digestive problems, including upset stomach, bloating, intestinal gas (flatulence), vomiting, and colic; for pain, including menstrual cramps, headache and toothache; and for mental disorders, including hysteria and melancholia.
Many people believe lemon balm has calming effects so they take it for anxiety, sleep problems, and restlessness. Lemon balm is also used for Alzheimer's disease, attention deficit-hyperactivity disorder (ADHD), an autoimmune disease involving the thyroid (Graves' disease), swollen airways, rapid heartbeat due to nervousness, high blood pressure, sores, tumors, and insect bites.
Lemon balm is inhaled as aromatherapy for Alzheimer's disease.
Some people apply lemon balm to their skin to treat cold sores (herpes labialis).
In foods and beverages, the extract and oil of lemon balm are used for flavoring.
How does it work?
Lemon balm contains chemicals that seem to have a sedative, calming effect. It might also reduce the growth of some viruses.
Possibly Effective for:
- Alzheimer's disease. Taking a standardized extract of lemon balm by mouth daily for 4 months seems to reduce agitation and improve symptoms of mild to moderate Alzheimer's disease.
- Cold sores. Applying a lip balm containing 1% lemon balm extract seems to shorten healing time, prevent infection spread, and reduce symptoms of recurring cold sores.
- Colic in breast-fed infants. A clinical trial shows that breast-fed infants with colic who are given a specific multi-ingredient product containing fennel, lemon balm, and German chamomile (Colimil) twice daily for a week cry for a shorter period of time than other breast-fed infants with colic.
- Upset stomach (dyspepsia), when a specific combination of lemon balm and peppermint leaf, German chamomile, caraway, licorice, clown's mustard plant, celandine, angelica, and milk thistle (Iberogast, Medical Futures, Inc) is used. This combination seems to improve acid reflux (GERD), stomach pain, cramping, nausea, and vomiting.
- Improving the quality of sleep, when taken with valerian.
- Restlessness (dyssomnia). Early evidence suggests that 1-2 tablets once or twice daily of a specific combination product providing 80 mg of lemon balm leaf extract and 160 mg of valerian root extract (Euvegal forte, Schwabe Pharmaceuticals) might decrease symptoms in children under age 12 whose restlessness is so extreme that it needs medical attention.
- Loss of appetite.
- Stomach and intestinal discomfort with bloating and gas.
- Sleeping disorders.
- A thyroid condition called Graves' disease.
- Promoting menstrual flow.
- Female discomforts.
- Insect bites.
- Nervous stomach.
- Attention deficit-hyperactivity disorder (ADHD).
- Other conditions.
