Citronella oil, with its distinctive lemony aroma, is much more than just a summertime staple for keeping mosquitoes at bay. This essential oil, derived from various species of Cymbopogon grass, boasts a rich history and a wide range of applications, from aromatherapy to industrial uses. This article delves into the diverse world of citronella oil, exploring its varieties, practical uses, purported benefits, and essential safety considerations.
The name "citronella" often evokes images of the familiar patio candles, but the botanical reality is more nuanced. Citronella oil is extracted primarily from two species of Cymbopogon grass: Cymbopogon nardus and Cymbopogon winterianus.
While both are sources of fragrant oil, their composition and characteristics differ slightly, leading to subtle variations in their properties.
The specific chemical composition of these oils can vary based on factors like climate, soil conditions, and the extraction method used, contributing to the overall character of the final product.
The primary active components contributing to the scent and properties of citronella oil include:
