How to extract essential oil at home? What are the methods?

1. Distillation is the earliest extraction method. With the change of the times, the equipment used has been obviously improved, but the principle is basically the same: put the aromatic plants into a distillation container, and then introduce high-temperature steam into it (or boil the spices with water). At this time, the essential oil containing aromatic components in plants will diffuse into the steam to form a boiling substance of oil and water; After that, the boiling substance is cooled, and the oil is insoluble in water and separated from water to form the required essential oil.

Distillation is very convenient and does not need to use chemical solvents, so it is still widely used now. Rose, lavender, rosemary, geranium, etc. This method is mostly used.

3. Squeezing method (squeezing method): by cutting, crushing and squeezing. Plant water and essential oil containing aromatic components are separated from raw materials to obtain a mixture of water and oil, and then the oil and water are separated by centrifugation, filtration and other methods to obtain essential oil.
