  • Citronella oil is one of the essential oils obtained from the leaves and stems of different species of Cymbopogon. The oil is used extensively as a source of perfumery chemicals such as citronellal, citronellol and geraniol. These chemicals find extensive use in soap, perfumery, cosmetic and flavouring industries throughout the world.

    Citronella oil is also a renowned plant-based insect repellent, and has been registered for this use in the United States since 1948. The EPA considers oil of citronella as a biopesticide with a non-toxic mode of action. Research also shows that citronella oil has strong antifungal properties,and effective in calming barking dogs.
