Everything is chemistry. Every cell, organ, and tissue in the body performs its function using enzymes, receptors, and other proteins, which work together to break down, build up, and rearrange the chemical bonds in biological molecules. Essential oils also operate under the principles of chemistry. In fact, the chemical makeup of essential oils is what gives them the ability to affect the body’s systems.

The doTERRA Oil Chemistry Handbook is a reference that will give you the information and the intellectual tools you need in order to understand how to use essential oils effectively based on their chemical properties. By understanding the fundamentals of oil chemistry, you can begin to classify oils by their chemical properties. This will help you learn which oils might have applications in different daily life contexts and how they work.
