Java Citronella
Constituents
This species is very closely related to Ceylon citronella (Cymbopogon nardus), and the two species have sometimes been treated as different forms of the same species, as Cymbopogon nardus mahapengiri (this species) and Cymbopogon nardus lenabatu (Ceylon citronella).
The plant is often cultivated, mainly in Java and other parts of southeast Asia, for the essential oil contained in its leaves. This oil is widely used in the perfumery industry. This species yields up to twice as much essential oil as the related Cymbopogon nardus (which is grown mainly in Sri Lanka), and the oil is of better quality.
Medicinal: Poultices of the leaves are used to treat minor cuts and bruises.
Extracts (the essential oil or a tea?) are used as a vermifuge and treatment for internal disorders.. They are mildly astringent and stomachic[
