Essential oils are so small in molecular size that they can quickly penetrate the tissues of the skin, are lipid soluble and capable of penetrating cell membranes, even if the membranes have hardened because of oxygen deficiency. According to Jean Valnet, M.D. essential oils can affect every cell in the body within 20 minutes.
Essential oils have a bio-electrical frequency that is several times greater than the frequency of herbs, food, even the human body, and are made up of the same elements as the human body, which are hydrogen, nitrogen, oxygen, carbon and sulfur. The oils also contain amino acid which are the building blocks of protein.
