Extraction Methods
Explore the various methods used to extract essential oils from plants.
Essential oils are obtained through various extraction methods, each designed to capture the unique aromatic and therapeutic components of the plant. The extraction process is crucial as it determines the purity, potency, and aroma of the resulting essential oil.
From steam distillation to cold pressing, these methods ensure that the essence of the plant is preserved, allowing the essential oil to deliver its maximum benefits. Understanding these methods can enhance your appreciation of the oils and help you choose the best options for your needs.
Steam Distillation
Steam distillation is the most common method for extracting essential oils, using steam to vaporize the plant material.
Cold Pressing
Cold pressing is a method used mainly for citrus oils, where the oil is extracted by pressing the plant material without using heat.
Solvent Extraction
Solvent extraction uses solvents like hexane to extract essential oils from delicate plant materials, producing a "concrete" and then a "absolute".
CO2 Extraction
CO2 extraction uses supercritical carbon dioxide as a solvent to extract essential oils, producing high-quality oils with a broad range of aromatic compounds.
Hydro Distillation
Hydro distillation is a variant of steam distillation where the plant material is directly immersed in water, and the water is then boiled.
Enfleurage
Enfleurage is an ancient method where flower petals are placed on a layer of fat to absorb their fragrance. This process is repeated until the fat is saturated with essential oil.
