Natural Essential Oils are mainly extracted from plant material using steam distillation which is a default extraction method of any oil. When we put the plant material into copper still (a big copper pot used to boil the plant material in Steam Distillation process) and start burning the furnace, the whole plant material break drown and steam starts uplifting after around 200 degree temperatures. This steam contains the molecules of that plant and according to its evaporating level they travel along with water vapor and collect into receiver. Further after boiling 3-4 hours, we make the furnace cool and wait until everything to cool down. The receiver contains the volatile essential oil of that particular plant material. At last we filter the oil from water.
