Advanced Graduate Program

Understanding The Practical Applications of Essential Oil Chemistry

Take your knowledge of essential oils to the next level!

The 125-hour Advanced Graduate Program is designed for Certified Aromatherapists who wish to continue their Aromatherapy studies online, deepen their understanding of the science of essential oils, and create therapeutic blends firmly grounded in chemistry and solid research.

During this professional level program, we'll take an in-depth look at 27 different essential oils and specific essential oil components. You'll learn about their molecular structures and therapeutic behaviors in language that's down to earth and makes learning the chemistry very practical.

Andrea has compiled scientific research on 48 major essential oil components into a user-friendly, searchable database (called the Aromahead Component Database). Membership to the database is usually $300, with a yearly renewal of $75, but you receive FREE lifetime membership when you register for the AGP! With the information in the AGP and the database, you'll be able to identify the medicinal actions of a particular oil or component quickly, and enhance your therapeutic blending skills.

Course Overview

Enrollment in the AGP includes FREE lifetime membership to an advanced database of researched essential oil components and their therapeutic properties (the Aromahead Component Database), developed by Andrea Butje and edited by Robert Tisserand.

In the AGP, you'll study less common essential oils sourced from plants grown and distilled in Madagascar, India, and Nepal (as well as several other countries). You'll also be guided through a detailed study and review of the chemical families.

When you complete the course, you'll be well versed in the most practical, scientific aspects of essential oil chemistry.

You will have mastered innovative blending techniques that take your skills as an Aromatherapist to a high level.

Goals and Objectives

  • Deepen your knowledge of essential oil chemistry, especially for oils that are less well known. This will also deepen your relationship with the oils, so that blending from a chemical component perspective comes easily.
  • Choose how to approach your blends for each unique person and situation by becoming well versed in eight advanced blending techniques:
    1. Blending from a single component perspective
    2. Blending from a multiple component perspective
    3. Blending within one chemical family
    4. Blending between several chemical families
    5. Blending with multiple oils that have two or more of the same components, in similar and significant percentages
    6. Blending from a plant family perspective (to take advantage of the synergy between botanical families)
    7. Blending from a plant part perspective (to address emotional balance)
    8. Blending from a country of origin perspective (which taps into an interesting look at oils sourced from the same country)
  • Expand your understanding of how to use GC/MS reports (Gas Chromatography/Mass Spectrometry), and how they relate to the therapeutic properties of essential oils.
  • Use the blending activities and chemical family worksheets to reinforce your knowledge of essential oil chemistry, so that you can immediately apply it to your blending.

This is an advanced course designed for Certified Aromatherapists.

Once you have enrolled in the AGP, you may begin your class right away. Students study at their own pace, supported by the instructors and the community on the Aromahead forum. Most students finish this course between 2-3 months, but there is no required time frame for completion.

This is an exciting, independent, self-study program. When questions arise while you're learning, you can ask both the Aromahead Institute's team and our graduates on the Aromahead forum. The forum is an active, engaged online community where Aromahead students and graduates come together to chat about Aromatherapy, share experiences, and answer questions.

Andrea and the Aromahead team will also provide in-depth personal feedback and support for your case studies so that you can take your blending skills to a new level of expertise.

- Patti Gelini

Certified Aromatherapist

I loved how essential oil chemistry and the chemical components are taught so well and that it was easy to grasp without a beginning knowledge of chemistry. It feels meaningful to know how essential oils work and now I can explain it. I enjoyed analzing the components and using the Aromahead Component Database.

- Eiko Thiele

Certified Aromatherapist

I loved extending my aromatherapy knowledge to include blending with lesser known, but powerful, essential oils as well as blending with carriers, hydrosols, and other mediums to create a broad spectrum of products that are relevant for my clients.

My understanding of chemical families grew by leaps and bounds as a result of the course — it added a whole other dimension to my blending to have a fundamental understanding of the chemical families and the key components found within them. The class helped me to deepen my understanding of the chemistry and science of aromatherapy so I can offer more compelling custom blends for my clients.

- Kristina Bauer

Certified Aromatherapist

In 2010 I had been practicing aromatherapy for nearly 20 years and knew it was time to deepen my knowledge of essential oiils. The Aromahead Advanced Graduate Program was perfect! Andrea's step-by-step method of teaching helped clarify my questions on chemistry, and I made friends with some fabulous new essential oils and carriers. Every class I take with Andrea Butje makes me a better Clinical Aromatherapist and Educator!

Aromatic Wisdom Institute


Aromahead Institute's 235-hour Aromatherapy Certification Program, or another school's 200-hour Aromatherapy Certification program is required.


Supplies are not included in the tuition.

We have designed a fully-stocked kit of essential oils, carriers, and bottles, sold through Aromatics International. The kit includes everything you'll need to make the recipes in this course, but it's not a mandatory purchase.

If you have your own essential oils and supplies, feel free to use them.

Many students choose to begin the class, and then decide which recipes they want to make. This allows them to purchase their oils and supplies over time, as they make their way through the course (instead of buying the whole kit up front).

Advanced Graduate Program Kit

Important Note: Purchasing the kit is optional. If you have your own essential oils and supplies you may use them.
