The distillation apparatus, commonly called a ‘still’, consists of a vessel for plant material and water, a condenser to cool and condense the vapour produced and a method of collection, or ‘receiver’. Material from the appropriate part of the plant for extraction is immersed in water in the distillation vessel. This is then heated to boiling point and the steam (water vapour) carries out the volatile oils. The water safeguards some components by preventing overheating as the temperature will not exceed 100 °C (the boiling point of water at normal pressure). However, the distillation can be a long process and the water may damage some other compounds.
