Melissa officinalis

Common Names: Lemon balm, bee balm, sweet balm, Melissa, garden balm

🧭 Description & Habitat

Lemon balm is a bushy, perennial herb in the mint family (Lamiaceae), growing up to 70 cm tall with crinkled, ovate leaves that emit a bright lemony scent when crushed. It produces small white or pale-yellow flowers that attract bees. Native to southern Europe and the Mediterranean, it’s now naturalised across temperate regions of the world. Prefers well-drained soil, full sun to partial shade, and is often found in gardens, hedgerows, and roadsides.

📜 History & Ethnobotany

Lemon balm has been used medicinally for over 2,000 years. In Classical Greece, it was associated with the goddess Artemis and used for "nervous disorders." The Romans introduced it throughout Europe. Medieval physicians, including Avicenna and Paracelsus, praised it as a remedy for melancholy and as a "tonic for the heart and mind." It was a key component of Carmelite water (a monastic tonic wine) and is still used in European herbal traditions for anxiety, digestion, and insomnia.
