Botanical Overview
Ceylon Citronella (Cymbopogon nardus) is a flowering plant in the Poaceae family. Traditional medicine systems have documented several valuable applications for this species, supported by its observed therapeutic effects. The grass family (Poaceae) includes annual and perennial herbs with hollow, jointed stems and narrow leaves with parallel venation. The flowers are reduced and arranged in spikelets, and the fruits are grains (caryopses). This family provides the majority of the world’s food calories through cereals.

General Description
C. nardus cannot be eaten because of its unpalatable nature and is an invasive species that renders pastureland useless, since cattle will starve even in its abundance.
Family Context
The Poaceae family is very large and globally distributed. Notable medicinal members include:
- Adlay — 54 documented uses
- Corn — 51 documented uses
- Rice — 47 documented uses
- West Indian Lemongrass — 43 documented uses
Geographic Distribution
Ceylon Citronella has been recorded in 10 countries and territories worldwide, including Brazil, Congo (DRC), Indonesia, India, Kenya, and others.
Traditional Uses
Ceylon Citronella has been traditionally used for digestive health, pain and inflammation, and nervous system disorders, among other applications.
Digestive health.
- Carminative
- Dyspepsia
For digestive complaints, the herb is typically prepared as a tea or decoction taken before meals. The bitter compounds stimulate digestive secretions and improve nutrient absorption. Some traditions use the powdered root or leaves in small doses as a stomachic tonic.
Pain and inflammation.
- Ache(Head)
- Anodyne
- Neuralgia
- Rheumatism
- Pain
For pain and inflammation, preparations are applied both topically as compresses and taken internally. A warm poultice draws blood to the area and promotes healing, while internal preparations address systemic inflammation.
Nervous system disorders.
- Spasm
Nervous system support involves taking the herb as a warm tea, often in the evening or before bed. The calming compounds interact with neurotransmitter systems to promote relaxation and restful sleep.
