The species originates from southern Europe, Asia and some parts of North America. It has been extensively used in the Mediterranean regions of Turkey and Morocco as a popular digestive tea. Historically, lemon balm held multiple uses, including being a natural flavoring additive for foods, a cosmetic, an herbal tea and a highly-revered essential oil. The plant was also traditionally used as a memory-enhancing herb, a mild sedative, an anti-bacterial agent and a sleep aid. In fact, historical record shows its use goes back to the Middle Ages, where it was employed as a stress-reducer, sleep-aid and digestive promoter.
HERBAL PROPERTIES AND USES:
Even pre-Middle Ages, this member of the mint family was used to treat a variety of health conditions. Steeped in wine, lemon balm was used to treat wounds, insect bites and stings, as well as lift the mood. Current medical research is looking into the use of lemon balm as an anti-tumor, antimicrobial, antihistaminic, anti-bacterial, antispasmodic and antioxidant agent. Studies have found that it is an effective aid for herpes, and it holds potential applications for moderate Alzheimer's disease, mild mood disorders, the stimulation of the immune system, and overall improvements in cognitive function. Multiple studies show that a combination of lemon balm with valerian, hops, and chamomile is an effective remedy for insomnia and nervousness.
