Solvent extraction: In this method, the oil is extracted from sensitive plant sections using either ethanol or hexane solvent.
The CO2 extraction method uses carbon dioxide to extract oil at low temperatures and high pressures. The carbon dioxide acts as a fluid, similar to a solvent, to extract the oil; when the pressure is raised, the CO2 evaporates and releases the oil.
Oils that have been derived from CO2 include chamomile, ginger, and frankincense.
The infused method involves soaking the plant material in a carrier oil, such as olive or jojoba oil, to extract the aromatic chemicals. The essential oils are not precisely these.
