Also known as "Indian verbena", Java citronella belongs to the Poaceae family. This plant is sterile, without flowering. As soon as the leaves are crushed, a distinctly lemony fragrance is released.
Before its introduction to Europe in the 19th century, the British and Dutch engaged in extensive maritime trade of it, as its fragrance was highly valued by the nobility. In exotic countries, Java citronella is still used today as a mosquito repellent; it is thus planted around homes.
From its long, narrow leaves with sharp edges, essential oil and hydrosol are extracted through steam distillation. This process involves carrying the aromatic molecules or volatile constituents (the essential oil) with the steam, then cooling this vapor which condenses in the essencier to produce the hydrosol. The latter is primarily composed ofgeraniol, citronellal, citral, geranial, neral, and alpha-thujene.
Unlike essential oil, there are no contraindications for the external use of lemongrass hydrosol. It can be used by pregnant and/or breastfeeding women as well as children. Sensitive to oxidation, it should be stored for 6 months after opening, preferably in the refrigerator. If you notice a change in appearance or smell, stop using your hydrosol.
