Les huiles végétales Vegetal oils, also known as Vegetable oils or plant oils, are extracted from oleaginous plants, i.e. plants whose nuts, fruits or seeds contain lipids. These oils contain many antioxidants, vitamins and fatty acids essential for the proper functioning of the body.
How are vegetal oils made?
There are many plant oils on the market but not all of them are of very good quality. In order to choose a better quality oil, it is important to look at how it is grown and extracted. In fact, it is the choice of extraction method that defines whether a vegetable oil is of the highest quality. There are several methods: cold pressing, hot pressing, maceration or solvent extraction. In order to obtain a very pure oil of maximum quality, extraction must be done by cold pressing or maceration for oils coming from plants.
Cold pressure extraction: In order to retain all its nutrients, nuts, seeds and dried fruit are sorted to retain only the best pieces. They are then passed through mechanical presses which crush the oleaginous fruit until a pure, high-quality oil is obtained that contains no foreign substances. The oil thus obtained is labelled "first cold-pressed oil".
Extraction by maceration: this method is reserved for plant oils obtained from a plant. In this case, the fruits, flowers or roots are used and placed for several weeks in a neutral vegetable oil (e.g. olive or sunflower oil). The oil thus obtained is filtered to preserve only the oily macerate.

Guide for the use of oils in aromatherapy
Most vegetable oils do not present any danger, but for safety reasons it is always advisable to be aware of possible contraindications before use.
It is also important to read the instructions for use of vegetable oils as some cannot be cooked and others are photo-sensitising and therefore cannot be exposed to the sun after application.
