How are essential oils made?

Essential oils are usually extracted by distillation, often by steam. Other processes include expression, solvent extraction, sputtering, absolute oil extraction, resin tapping, wax embedding, and cold pressing. Essential oils are basically plant extracts. They are made by steaming or pressing several parts of a plant (flowers, bark, leaves or fruits) to capture the compounds that produce the fragrance.

It may take several kilos from a plant to produce a single bottle of essential oil. In addition to creating aroma, essential oils also perform other functions in plants. They are essentially the liquefied version of a plant, and they allow their beneficial compounds to reach the bloodstream faster than they would simply by consuming the plant. Steam distillation is the most popular method for extracting and isolating essential oils from plants for use in natural products.

The term is generally preferred, since it produces an essential oil with a superior odor compared to distillation. Therefore, the CO2 extraction process could produce higher quality oils that have not been altered by the application of high heat, unlike the steam distillation process. This method uses food-grade solvents such as hexane and ethanol to isolate essential oils from plant material. Now, as the pendulum swings from the recipe book to the energy of the plants, it's a good time to make sure you understand what essential oils are, how they are made, and how to use them safely and effectively.

The CO2 returns to natural pressure and evaporates back to its gaseous state, while what is left is the resulting oil. Recall that freshly distilled essential oil does not always have a pleasant smell, because it needs to mature for a few weeks, in which it must be allowed to mature. There is evidence to support the use of lavender essential oil as an analgesic (analgesic), anti-inflammatory and topical antibiotic, so it is very helpful to keep it close to burns and insect bites. The oil and juice that are produced still contain fruit solids, such as peel, and must be centrifuged to filter solids from liquids.

The essential oil produced is a very delicate substance that can easily change and become rancid, thus losing its natural aroma and developing substances that could also be harmful. It is best suited for plant materials that produce low amounts of essential oil, which are largely resinous, or that are delicate aromatics that cannot withstand the pressure and distress of steam distillation. This term refers to the use of essential oils to improve the quality and feeling of health and well-being on a physical, emotional and mental level. These absolutes are very aromatic and tend to be more viscous (some are very resinous and difficult to work with) and dark in color compared to essential oils obtained by cold pressing or distillation.
