How is Patchouli Essential Oil extracted from the plant material?

Patchouli essential oil is extracted from the leaves of the patchouli plant, scientifically known as Pogostemon cablin, through a process called steam distillation. The leaves of the plant are first dried and then crushed or shredded to release the essential oil. The crushed plant material is then placed in a distillation chamber, and steam is introduced, causing the oil molecules to separate from the leaf material. The steam, carrying the essential oil, is then condensed back into a liquid and collected separately. The resulting liquid is patchouli essential oil, known for its exotic, earthy scent and numerous therapeutic properties.
