Overview
Lemon balm has been cultivated for over 2,000 years. The name "Melissa" comes from the Greek word for honeybee, as the plant is highly attractive to bees. In medieval times, it was used to treat melancholy and was considered a valuable medicinal herb by famous physicians like Paracelsus and Avicenna.
The leaves have a pleasant lemon scent due to citral and other volatile oils. It is one of the gentlest nervine herbs, suitable for children and the elderly, and can be enjoyed as a daily tea without concern. Its calming effects are subtle but effective, especially for stress-related digestive issues.
How It Works
Lemon balm works primarily through the GABA system, inhibiting the enzyme that breaks down GABA and allowing more of this calming neurotransmitter to remain active. It also appears to have effects on acetylcholine receptors, which may explain some of its cognitive benefits.
The rosmarinic acid in lemon balm has antiviral properties, particularly against herpes simplex virus, which is why it is traditionally used for cold sores. It also has mild antispasmodic effects on the digestive tract, relieving cramping and nervous stomach.
What It's Used For
