Essential oils are highly concentrated natural plant extracts; a drop or two can produce significant results. An entire plant, when distilled, might produce only a single drop of essential oil. That is why their potency is far greater than dried herbs. Pressing or distillation extracts the subtle, volatile liquids from plants, shrubs, flowers, trees, roots, bushes, and seeds, that make up essential oils.

Essential oils are the life-blood of the plant, protecting it from bacterial and viral infections, cleansing breaks in its tissue and delivering oxygen and nutrients into the cells. In essence, they act as the immune system of the plant. That is why they are so essential to the plant -- without them, plants could not survive.

In the human body, they have a similar action -- such as transporting valuable nutrients to the cells; increasing oxygen intake, and digesting toxic waste in the blood. This is because the three primary elements - carbon, hydrogen and oxygen-are common to both human beings and essential oils. This shared chemistry makes essential oils one of the most compatible of all plant substances with human biochemistry.

Not only that, but the lipid-soluble structure of essential oils and the fact that they have a protein-like structure similar to human cells and tissues makes them even more compatible with human tissue.

Essential oils are very different from vegetable oils (also called fatty oils), such as corn oil, olive oil, peanut oil, etc. Fatty oils are produced by pressing nuts or seeds. They are quite greasy, are not antimicrobial nor help transport oxygen, and will go rancid over time. Essential oils, however, are not greasy nor do they clog the pores like vegetable oils can.
