What is Lemon Balm?

Its leaves have a delicate, refreshing lemon scent and flavor with a hint of mint. While it shares many characteristics with other mints, such as its square stems and tendency to spread, its distinct aroma and slightly rougher leaf texture set it apart. For centuries, lemon balm has been cultivated not only for its pleasant taste but also for its therapeutic properties, which include aiding digestion and promoting relaxation.

Nutritional and Health Benefits

Beyond its uses in cooking, lemon balm is known for several potential health benefits, largely attributed to its antioxidant-rich compounds like flavonoids and phenolic acids, including rosmarinic acid.

Key benefits include:

Improved Digestion: As a member of the mint family, lemon balm can aid the digestive system. It helps reduce bloating, stomach cramps, and indigestion.

Improved Sleep: By reducing anxiety and promoting relaxation, lemon balm can help with insomnia and improve overall sleep quality.
Antiviral Action: Lemon balm has antiviral properties, and topical application of extracts has been shown to reduce healing time and severity of cold sores caused by the herpes simplex virus.
Enhanced Cognitive Function: Some research indicates that lemon balm may have a positive impact on cognitive performance, including memory, learning, and mood.

Culinary Uses for Lemon Balm

Lemon balm's mild, citrusy flavor makes it a versatile ingredient in both sweet and savory dishes. Its delicate taste is best when the leaves are fresh, as the flavor diminishes significantly when dried.

Common culinary uses include:

Teas and Infusions: One of the most popular uses is steeping fresh or dried leaves in hot water to create a soothing, flavorful tea.
Desserts: Mince fresh leaves to add a unique flavor to ice cream, sorbet, fruit salad, or cookies.
Savory Dishes: Chop the leaves and add them to sauces for fish or chicken, mix them into herbed butter, or sprinkle them over roasted vegetables.
Drinks: Infuse sprigs of lemon balm into water, lemonade, or cocktails for a refreshing, aromatic twist.
Vinaigrettes and Dressings: Mix chopped lemon balm into herbal vinegars or salad dressings for a bright, zesty flavor.
