Lemon Grass
Cymbopogon citratus
Family: Gramineae | Parts Used: Leaves
Lemon Grass is a citrus-scented herb with a fresh, bright aroma, used traditionally for fevers, colds, indigestion, and respiratory complaints. Its essential oil contains citral, geraniol, and related compounds that contribute to its febrifuge, carminative, and expectorant actions. In Caribbean and Ayurvedic traditions it is also used in spiritual baths and cleansing preparations, and the essential oil is a well-known natural insect repellent.
Traditional Uses
- Colds, flu, and fevers
- Indigestion and digestive support
- Respiratory support; used as an expectorant
- Gentle detoxification and blood purification
- Natural insect repellent (essential oil)

Spiritual & Folk Uses
In Caribbean folk practice, lemon grass is traditionally used in spiritual baths and floor washes to clear negative energy. The essential oil is also used for warding off insects, a practical application that blends with its cleansing associations across multiple traditions.
Bonnie's Notes
I reach for lemon grass most often in spiritual baths and cleansing preparations. The essential oil is one I keep on hand specifically for insect repellent, especially through the warmer months.
