And the leaves of the tree are for the healing of the nations.
Essential oils are the unique, aromatic compounds found in plants. These natural extracts come from leaves, stems, roots, barks, flowers, fruits, and seeds. How do essential oils really work? What we perceive as the simple fragrances of plants, are actually the aromatic compounds which provide plants with protective, reproductive, and regenerative properties. People can also benefit from the chemical constituents of essential oils through aromatic, topical, and internal applications.
The Importance of Quality: Essential oil quality is directly affected by the geographic location of the plant, time of year the plant was harvested, and method of extraction. Pure, therapeutic-grade essential oils reflect the same properties of the plants from which they were derived and humans can benefit from the same protective, regenerating, and immune-strengthening properties. Therefore, it is important you only use pure, therapeutic-grade essential oils as they will exhibit the chemical constituents of the original plant, maintaining the integrity of the desired plant properties.
A Brief History: Essential oils have been used for centuries by many cultures around the world for a variety of purposes. Did you know that essential oils are referenced in both ancient Egyptian hieroglyphics and Chinese manuscripts? Additionally, essential oils have religious connections as they are mentioned throughout the Bible.

Extraction Methods: There are two main methods for essential oil extraction – steam distillation and cold expression.
- The primary method for essential oil extraction is steam distillation. Through this method, the plant material is placed in an extraction chamber and the chamber is infused with steam. The vaporized water and essential oil will exit the extraction chamber through a cooling system which separates the water (condensed from the steam) and the extracted essential oil. Steam distillation accounts for over 90% of essential oil extraction. This method is effective as essential oils are volatile and hydrophobic. Essentially, this means essential oils are easily evaporated and repel water.
- The other method, cold expression (or cold pressing), is utilized to extract essential oils from citrus peels and rinds. Citrus essential oils include Lemon, Wild Orange, Lime, Bergamot, Grapefruit, and Tangerine!
Okay, okay…I will wrap up my little science lesson. I believe it is critical you have an essential oil foundation before you begin using essential oils. Gaining some basic knowledge will be immensely beneficial as you begin incorporating your new “oily” friends into your life. However, if you do want to geek out on the science of it all, I highly recommend investing in this book. Modern Essentials dives into the nitty gritty details of the chemical constituents and how they work with the human body.
I know you are probably getting excited to learn about the many essential oils available and how they can enhance your life! Trust me, our exploration process will begin soon! But first – I want to make sure we really enhance our knowledge about holistic health and personal empowerment before we jump into playing with the oils.
