Lemongrass (Cymbopogon citratus): The Citrus Digestive Herb

Lemongrass — Cymbopogon citratus — is a tall, tropical grass native to South-East Asia and widely used in both the kitchens and the medicine traditions of South and South-East Asia, the Caribbean, and West Africa. Its fresh, intensely lemony scent — derived from the high citral content of its essential oil — is immediately recognisable, and the medicinal use of this aromatic grass spans digestive support, antimicrobial activity, anti-inflammatory joint support, and nervous system calming. As both a food and a medicine, Lemongrass exemplifies the dietary medicine principle — where regular culinary use provides ongoing, gentle therapeutic benefit.

At Herba Naturalle, Lemongrass is listed in the comprehensive herb index as an aromatic digestive and anti-inflammatory herb.

Active Compounds

• Citral (neral and geranial, 65–80% of essential oil) — the primary active compounds; antimicrobial, antifungal, anti-inflammatory, antioxidant, and sedative
• Geraniol and citronellol — antifungal and insect-repelling volatile compounds
• Quercetin and luteolin — flavonoids with anti-inflammatory and antioxidant activity
• Chlorogenic acid — antioxidant and anti-inflammatory

Clinical Applications

Digestive Support

Lemongrass is a gentle carminative and digestive antispasmodic — relieving flatulence, bloating, and intestinal cramping through its volatile oil content. Used throughout South-East Asia as a post-meal digestive drink and as a remedy for gastritis, nausea, and functional dyspepsia. Complementary to the Digestive Reset Bundle.

Antimicrobial and Antifungal

Citral demonstrates significant broad-spectrum antimicrobial and antifungal activity — relevant in gut dysbiosis, fungal skin infections, and as a supportive antimicrobial in respiratory infections. The Berberis Plus provides more targeted gut antimicrobial support.

Fever and Infection

Traditional use as a fever herb across West Africa and South-East Asia — the diaphoretic and anti-inflammatory effects support fever resolution. Relevant to the Stop the Inflammation Pandemic: Breathe Easy context.

Joint Pain and Anti-Inflammatory

Clinical studies show meaningful reductions in knee osteoarthritis pain with topical Lemongrass oil — the anti-inflammatory citral compounds reduce local inflammatory signalling. Relevant to Inflammation in Muscles and Joints.

Nervous System

The volatile oil compounds have mild anxiolytic effects — Lemongrass tea is used throughout South-East Asia as a calming evening drink.
