Nomenclature of essential oils
AFNOR standard of essential oil
Only an essential oil obtained by the distillation of a botanically defined plant in a alambic using low-pressure water vapour corresponds to the AFNOR standard (AFNOR NF - T75.006 - 10/87)
The product, obtained by mechanical expression on citrus should be called petrol and not essential oil.
There is a nomenclature specific to essential oils that will allow you to identify in a certain way essential oil which you are looking for:
- The Latin name
The French name is insufficient to recognize it. For example, there are several kinds of lavender essential oils. The properties can vary from one way to another. Always refer to the Latin name that has been prescribed by a naturopath.
- The chmotype
The chmotype allows to identify the majority biochemical components of a essential oil. For more information, see our lexicon on essential oils.
- The extraction process
Apart from some plant species such as citrus fruit extracted by cold expression, most essential oils are obtained by distillation. But there are several distillation techniques. To improve yield, some producers use solvents or other essential oils, which destroys certain substances originally present in plants. We advise you to choose pure and natural "AB" (Biological agriculture) oils, which attests that oils are obtained by distillation process at controlled temperature and at low pressure.
- The origin of extraction
We can extract the essences from different parts of the plant: flower, leaf, root, seed... This origin is not anodine. It is generally recognized different properties depending on the source of gasoline.
