How Are Essential Oils Extracted?

  • 3 min read

Essential oils have become increasingly popular among buyers for their various benefits and uses. 

From aromatherapy to skincare, these potent oils offer a natural and aromatic way to enhance well-being. 

But have you ever wondered how essential oils are extracted? 

In this article, we will delve into the fascinating world of essential oil extraction, exploring different methods used to obtain these precious oils. 

Understanding the extraction process can deepen your appreciation for the quality and efficacy of the essential oils you purchase.

  • Steam Distillation

  • Steam distillation is the most common method used to extract essential oils from plants. In this process, steam is passed through plant material, causing the release of volatile compounds. The steam carries these aromatic compounds through a system of tubes, where it condenses back into water. The oil and water are then separated, resulting in the extraction of essential oil. This method is suitable for plants that contain essential oil in their leaves, flowers, or stems.

  • Cold-Press Extraction

  • Cold-press extraction is primarily used for obtaining essential oils from citrus fruits like oranges, lemons, and grapefruits. In this method, the peel of the fruit is mechanically pressed to release the essential oil. The oil-rich glands in the peel rupture, allowing the oil to be collected. Cold-press extraction is a simple and efficient method that preserves the natural aroma of the citrus oils.

  • Solvent Extraction

  • Solvent extraction is employed for plants that contain delicate or heat-sensitive aromatic compounds. In this method, a solvent, typically hexane, is used to dissolve the essential oil from the plant material. The solvent is then evaporated, leaving behind the concentrated essential oil. This process is more complex and requires additional steps to ensure the removal of residual solvents. It is commonly used for extracting oils from flowers like jasmine and rose.

  • CO2 Extraction

  • CO2 extraction is a more advanced method that utilizes carbon dioxide in its supercritical state to extract essential oils. In this process, carbon dioxide is pressurized until it becomes a liquid and acts as a solvent to extract the aromatic compounds from the plant material. The CO2 is then returned to its gaseous state, leaving behind a pure and high-quality essential oil. CO2 extraction is known for its ability to yield oils that closely resemble the natural plant constituents.

  • Distillation by Expression

  • Distillation by expression, also known as expression or enfleurage, is a traditional method used for extracting oils from delicate flowers such as jasmine or tuberose. In this process, plant material is soaked in an oil or fat to absorb the aromatic compounds. The oil or fat is then washed with alcohol to separate the essential oil. While this method is less commonly used today, it has historical significance in the extraction of certain floral oils.


    The extraction of essential oils is a meticulous and intricate process that involves different techniques tailored to each plant's unique characteristics. Whether through steam distillation, cold-press extraction, solvent extraction, CO2 extraction, or distillation by expression, each method plays a crucial role in capturing the aromatic compounds that make essential oils so valuable.

    By understanding the extraction process, buyers can appreciate the craftsmanship and care involved in producing high-quality essential oils. The next time you use an essential oil, take a moment to consider the artistry behind its extraction and the natural essence it brings to your well-being.
