Are the types and uses of essential oils different due to different extraction methods? How different, please specify

Generally speaking, the extraction process of essential oils is determined by the nature of the plant itself, such as citrus essential oils can not be heated and high oil yield, most of the cold-pressing method, the only Lime essential oils with distillation to get the quality of better than with the effect of the pressing method, so it is different; most of the essential oils, such as essential oils such as flowers, most of the distillation method, but jasmine flowers are more delicate, with the distillation method of heating can not be very well extracted Essential oil, so now more solvent extraction method to get the net oil, but because of the solvent residue, can not be used as aromatherapy; the best method of extracting jasmine essential oil is the supercritical carbon dioxide extraction method, to get the best quality of essential oils, the most pure aroma, the best results, such as the "Kainai" jasmine that is extracted using this method, given the complexity of the extraction process and the requirements for equipment. The extraction process is complex and the equipment requirements are high, so the price is relatively high.

So it's not so much the extraction process that makes a difference, but rather the fact that different essential oils need to be extracted in the most appropriate way in order to get the best quality. The best extraction process is supercritical extraction, but many oils are still extracted using traditional extraction methods because they are too expensive.

Each single essential oil has a different effect depending on the ingredients it contains. I won't go into detail here because there are too many varieties of essential oils.

The use of essential oils is very diverse, but in addition to lavender and tea tree, which can be used directly in small quantities, the other essential oils need to be blended with carrier oils for proper use. The so-called pure essential oil is not diluted by the base oil essential oils, divided into a single essential oil (extracted from a single plant) and compound pure essential oils (by two or more than two single essential oils mixed) two, can not be directly in contact with the skin, you can dilute the base oil to do the massage, but also can be used to point the aromatherapy lamps, put into the humidifier, soak the bath, foot bath, and so on. Diluted essential oils with carrier oils are called compound massage oils, and are generally only used for massage, but the effects of different formulas are completely different.

The concept of aromatherapy oils is not really accurate, but according to the industry, it may mean compound massage oils. There are also some flavors or compound massage oils masquerading as pure essential oils, you need to know how to identify them!
