How Essential Oils Are Being Extracted From Plants The essential oils that are often used in aromatherapy are often extracted from roots, leaves of plants, barks and flowers. The process of which essential oils are extracted from the said sources are called as distillation. The distillation process is a lengthy process but, this ensures the extraction of oil without affecting the quality. Distillation is basically the way of extracting the component required from the liquid through process of condensation and heating. As a matter of fact, there are different ways of distillation for essential oils and this includes: Water distillation – what is done here is pouring the water first in a container and other raw materials as well for boiling. The oil is separated from water since water and oil are insoluble substances. The separated oil is then stored in a container for further use.
The Best Advice on Oils I’ve found
While the process may sound simple, it’s actually a tedious one that is quite time consuming. This said method is helping in maintaining oil properties as the water prevents it from overheating and thus, it restricts evaporation of the beneficial components in it.

Steam + Water Distillation – steam as well as water together is pushing the oil out on plants and from that point, the essential oils are gathered which leaves the steam behind. Steam Distillation – for this process, the plant extracts are placed in a container and a lid is put on it so by that, the steam won’t evaporate. Extracts are steamed as long as it begins to release oil. It is important to have a controlled temperature while doing this method. The temperature should be set accordingly and it must be enough for extracts to release the oil and not burn it. After the steam process is done, the steam containing the essential oils are condensed by passing it in a specialized cooling system. The steam condensed will form liquids from where water is separated from the oil. Not just the process is cumbersome but at the same time, it only extracts little amount of oil. Hydro Diffusion – instead of the bottom, the steam is fed from top of the botanical material when doing this distillation process. Cohobation – when doing this method, it normally extracts rose oil. The process uses water distillation to make rose oil. The oil is being extracted and its components are named as phenyl ethyl alcohol are dissolved to distilled water and doesn’t form a part of extracted essential oils. Phenyl ethyl alcohol is distilled from water and added back to oil in proper proportion to form rose oil. Not to mention, the whole process is also daunting and lengthy.
