Melissa belongs to the Lamiaceae family and comes from the Mediterranean. Due to its characteristic citrus fragrance, it is also known under the name lemon balm. The leaves of balm contain a precious essential oil and Hildegard of Bingen recommended the herb as an “agent that invigorates the heart”. Due to the herb’s beneficial nature, balm was grown in monastery gardens during the Middle Ages and made into an alcoholic beverage, which served to relieve digestive disorders. Today, balm oil is used to calm nervous, anxious people and has shown itself to be effective in treating sleeping disorders.
