Origin of the essential oils

Natural essential oils come from plants all over the world, but mainly of the warm climates, because most of them need a lot of sun and heat to be able to produce essential oils. They are formed in the oleaginous vesicles and they accumulate in diverse parts and organs of the plants: flowers, leaves, and seeds, skin of the fruits, roots, barks, marrow or woody stems. Some plants only need some heat to give its aroma, while in other parts it can be necessary to cut them, to press them or even to crush them.

If essential oils of plants are extracted that have been cultivated in a conventional way they can contain remains of fertilizers or pesticides that act as pollutants and can give allergic reactions or cause allergies. Therefore, it is important to always use oils of plants that are guaranteed biologically natural cultivations, that is to say organic, or a plant that has been cared for with natural means. Compared with those that have been grown with synthetic products or that have at some point been added any synthetic products in any phase of their growth. The best and most appreciated essential oils are those coming from wild plants.

The form of obtaining the essential oil of a plant depends on the part of the plant you are using to extract the oil. The most common method is the distillation with vapor, in a still; it makes the plants liberate their essences in boiling water or in the vapor of water.
