Citronella Essential Oil:
Citronella is a type of grass. It is used as a culinary and medical herb due to its lemony fragrance. The citronella oil is distilled from the leaves of citronella grass.
Distilling an essential oil is both an art and science. In this method, the steam is used to rupture the membranes of the source to release the oils. The steam with the oil compounds is then collected in a condenser where the oil is separated from the water vapour to form pure essential oil.
