Citronella oil is extracted from Cymbopogon nardus (also known as Andropogon nardus) and is of the Graminae (Poaceae) family.
Although this essential oil has been typecast as an insect repellant (especially for malaria carrying mosquitoes), it also has great benefit in clearing the mind, refreshing rooms and for softening skin, while combating oily skin and sweaty feet.

Citronella oil is extracted from a hardy grass, native to Sri Lanka and Java. This aromatic perennial grows about 1meter (3 feet) high and is a popular ingredient in wax candles, as an insect repellant, and is also widely used in perfumes, soaps, skin lotions and deodorants.
Citronella oil is extracted by the steam distillation of finely chopped fresh, dried or part-dried grass.
