Origin: Java / Grass Citronella is an essential oil with a sharp grassy aroma used primarily as a natural pest repellent but is also known to be emotionally uplifting and stress reducing. It can be a skin irritant so best to use cautiously and highly diluted if using as a topical mosquito repellant. Pure essential oils are highly concentrated liquid extracts from plants. Aromatic selections of plant varieties include leaves, roots, seeds, stems, fruit, peel, buds, flowers, wood, bark, saps (resins) and herbs. The essential oils are released as an aromatic liquid during the process of distillation or expression. All our essential oils are ethically sourced and are premium grade, 100% natural, biodegradable substances of botanical origin.
