The pressure is then reduced, allowing the CO2 to evaporate, leaving behind a pure, high-quality oil that is often more expensive but exceptionally aromatic. Alternatively, expression, also known as cold pressing, is a mechanical process primarily used for citrus peels like oranges and lemons.

This commitment to integrity is what separates genuine therapeutic-grade oils from inexpensive imitations. The steam vaporizes the volatile aromatic compounds, and the resulting vapor mixture is then condensed back into a liquid.
This condensate is collected in a separator where the oil and water naturally separate due to their immiscibility. Understanding how are essential oils made reveals a world of specialized techniques, each designed to coax these potent molecules from botanical matter while preserving their integrity.

Trained professionals assess the oil using organoleptic testing, evaluating its color, viscosity, and, most importantly, its aroma. When pressurized CO2 passes through the plant material, it acts as a solvent, pulling out the essential oils.
