Lemon Balm: Melissa Officinalis

A Nurturing Herb for Calm, Digestion & Nervous System Support

Lemon balm (Melissa officinalis) is a gentle yet powerful herb traditionally used in naturopathic and herbal medicine to support the nervous system, digestion, and overall wellbeing. With its uplifting citrus aroma and calming properties, it has long been valued as a restorative herb for both mind and body.

Lemon balm is a perennial herb from the mint family (Lamiaceae) super easy herb to grow for beginner gardeners I always have it growing in mine, but you know what a mint plant is like- don’t plant it directly into your garden bed unless you want the entire garden to be lemon balm! Lemon balm is characterised by soft, heart-shaped green leaves with a super yummy lemon scent when crushed. It typically grows 30–90 cm tall and produces small white or pale yellow flowers. Native to the Mediterranean and parts of Western Asia, it is now grown worldwide.

Lemon balm has been used for centuries in traditional herbal systems, including Greek, Roman, and medieval European medicine. Historically, it was prescribed for:

• Menstrual irregularities

It was often referred to as a “heart tonic” and mood-lifting herb, used to “gladden the spirit.”
