Product Abstract
Citronella oil comes from the Asian grass plant known as Cymbopogon nardus. It’s most commonly used as a natural fragrant oil, in insect repellents, as well as in beauty, household and perfume products.
According to dozens of clinical studies, pure citronella oil is an antiseptic, antimicrobial and antifungal treatment. The most popular use for citronella is as a constituent in homemade or commercially sold insect repellents, since it naturally repels mosquitos and other bugs. The U.S. Environmental Protection Agency considers citronella to be a “biopesticide” that has a nontoxic mode of action against insects.

The oil is used extensively as a source of perfumery chemicals such as citronellal, and geraniol.
