Citronella essential oil is most commonly known for its use as an insect repellent; however, citronella oil also has other properties and use in aromatherapy.

Citronella (Cymbopogon nardus) has been used to treat rheumatic pain in the practice of traditional Chinese medicine; in many cultures, the leaves of citronella have been used for both aromatic and medicinal properties including the treatment of fevers, menstrual difficulties, digestive problems, intestinal parasites and also as use as an insect repellent.

Although citronella essential oil is considered to be a non-irritant and non-toxic, it may cause dermatitis in some cases; the use of citronella should be avoided during pregnancy. As is the advice when using any essential oils, a qualified aromatherapist should be consulted if unfamiliar with the use of essential oils and aromatherapy.
