Hey there!
Welcome to our blog series dedicated to the artful science of aromatherapy and essential oils. Art and science, you ask. Yes, there is the art, the intuitive, creative aspect of using essential oils, and the science rooted in organic chemistry. At their essence, essential oils are volatile (meaning they evaporate quickly) compounds (having many chemicals.)
Whether you’re a complete newbie or a seasoned pro, we’re here to share some wonderful insights into these incredible oils. Our series is full of fun and engaging content that will guide you through all the ins and outs of essential oils to help you gain knowledge and confidence. The subject matter is broken down into digestible bite-sized pieces. So, if you need to explore the material on dilution, you won’t have to wade through a bunch of information to get what you need. We will explore some of the chemistry that you might want to consider, the extraction methods (this matters), and other topics that will aid you. Our goal is to help you have the assurance you need so that you can use essential oils in your health and wellness pursuits. They are powerful allies in your health and wellness toolbox.
So, get ready to learn and have fun with us as we explore the fascinating world of essential oils together!
What Are Essential Oils?
Plants, trees, and shrubs contain oils, which are extracted. These form a concentrated substance we call essential oils. The oils acquire the plant’s essence, aroma, and therapeutic properties through various methods of extraction, though the most common is distillation or cold pressing. Each essential oil contains a complex mixture of chemical constituents, which gives it unique characteristics, aromas, and health benefits.
A single oil may contain 50 to 100 chemicals or more that act synergistically to provide benefits that are more powerful than either alone. Lavender (Lavandula angustifolia), for example, contains both linalool and linalyl acetate. These two chemicals have complementary effects on the nervous system. Linalool is a terpene alcohol with sedative, anti-inflammatory, and analgesic properties. Linalyl acetate is an ester with relaxing, antispasmodic, and anti-anxiety properties. These two chemicals working together contribute to Lavender’s therapeutic benefit.
Many parts of the plants, trees, and shrubs are used, including flowers, stems, roots, bark, seeds, and peels. These are used in varying quantities to extract essential oils. For example, to make 1 ounce of rose essential oil requires 625 pounds of rose petals, while sweet orange takes ~75 pounds of peel. Rosemary is extracted from the leaves and flowers of the Rosmarinus officinalis shrub, while citrus oils are extracted from the fruit’s peel. Neroli and Petitgrain (Citrus aurantium var. Amara) are both extracted from the bitter orange tree and have the same Latin name, but Neroli is extracted from the flowers while Petitgrain is extracted from the leaves and twigs. Though similar, they have different chemical makeups.
Factors affecting the chemical makeup include the species and variety of the plant (tree or shrub), environmental conditions, location, harvesting, and extraction method. While these affect the chemical composition of the oil, the factors that you need to consider when choosing an oil are examined in <Choosing the best Oil>, which considers things like the Latin name, GCMS testing, country of harvesting, and other factors that affect the makeup and quality of the oil.
The Chemistry Behind Essential Oils
At the heart of an essential oil’s therapeutic properties lies its chemistry. Comprised of fifty to several hundred chemical compounds, essential oils are complex. Some of the more commonly known chemicals are terpenes, esters, alcohols, aldehydes, and ketones. These molecules interact with the body in myriad ways, influencing physical health, emotional well-being, and cognitive function. Chemistry is a complex area of study. We aim to give you a working knowledge of the chemical constituents commonly used and an awareness of the chemical underpinning of essential oils. So head on over to <Chemistry in Brief> and get started.
Distillation Methods
Steam distillation is the most commonly used extraction method for many essential oils. It is a process that involves passing steam through plant material to vaporize the volatile compounds. These vapors are then condensed back into liquid form. Other methods include cold pressing, mainly used for citrus oils, and solvent extraction, which is often employed for very delicate plant materials that cannot withstand the heat of distillation.

A Brief History of Modern Usage
Evidence dating back thousands of years suggests the use of aromatic plants. In India, for example, the use of marigolds was prolific, and while there is no direct historical evidence, some have suggested that the ability to count and record the number of flowers and track how many each temple received contributed to the development of math. Ancient civilizations used them for embalming, religious ceremonies, and health care. In modern times, using essential oils has evolved into a sophisticated branch of herbal medicine known as aromatherapy. Today, essential oils are used for various purposes, from natural health care and holistic healing to enhancing emotional well-being and creating natural perfumes.
