Essential Oils are nothing like typical oils such as vegetable, nut or seed oils. Although they share the word “oil” in their name, they are molecularly quite different. A vegetable based oil, like Almond, Avocado, Argan and Jojoba are the viscous lipid (fatty) substances that are produced after cold pressing the nuts, seeds and fruits.
An Essential Oil, on the other hand, is the volatile aromatic substance extracted from an aromatic plant, like Lavender. It is highly concentrated and molecularly complex, and contains the healing force, or “essence” of the plant, which has been estimated to be 75 to 100 times stronger than the dried plant material on its own.
To call these uniquely powerful and dynamically rich substances “oils” is slightly misleading, because a genuine and authentic Essential Oil does not feel “oily” or “greasy,” but rather evaporates quickly and feels dry to the touch. The reason why they are referred to as “oils” is due entirely to their lipophilic (fat loving) nature, meaning they are not water soluble.
Furthermore, all plants produce Essential Oils which are essential to their survival, however, not all aromatic components, can be picked up by scent. The human sense of smell is not as robust as animals or insects, and is therefore limited in the quantity and range of aromatic plants that we can smell.
Essential Oils never dissolve in water, or leave a greasy residue or film on clothing or on paper. They evaporate and volatilize quickly, and feel dry and light to the touch. They should always be kept out of direct sunlight, or direct heat, and should never be ingested (unless under the expert guidance of a qualified Aromatherapist).
