What exactly makes up an essential oil? Which atoms and molecules are most important to understand the chemistry of essential oils? Come join us for this beginner-friendly exploration of the chemistry of essential oils.
With her signature enthusiasm, Dr. Joy Bowles will introduce you to the world of organic chemistry.
As both a scientist and an experienced aromatherapist, she has a unique insight into how essential oils interact with our body on the cellular level, and will help you gain that insight through the amazing language of chemistry.
Understanding the molecular makeup of essential oils will help you make better therapeutic decisions, as well as accurate safety assessments. Don’t miss out on this unique opportunity to learn fundamental chemistry from the expert, and join us on our dedicated Tisserand Institute learning platform!

Aromatherapist and International Speaker
In 1991, Dr. Joy Bowles wrote the first course in essential oil chemistry in Australia. Her book The Chemistry of Aromatherapeutic Oils, published in 2003, is a standard text for aromatherapy courses around the world. This work moves step-by-step at the molecular level through 89 essential oils, along with techniques for applying the benefits of aromatherapy to the various body systems.
For her PhD, awarded in 2007, Dr. Joy investigated the effects of essential oils on cognitive function in dementia. After several years in primary healthcare, she’s returned to the field of essential oil chemistry, training practitioners on the evidence-based therapeutic effects of essential oils. Helping people understand the chemistry and pharmacology of essential oils is one of her life’s passions.
Lesson 1 - Chemical Structure & Analysis
- GC-MS analysis and examples of whole essential oils and their constituents
- Acids, lactones, furans, furanocoumarins, diterpenes, diketones, peroxides and sulfur compounds
- Differences in composition of steam-distilled essential oils, solvent-extracted absolutes, super- and sub-critical C02 extracts
- Effects of constituent concentration on essential oil properties
- Constituent profiles: bergapten and coumarin
Lesson 2 - Chemical Relationships
- Chemical names that sound similar but have different endings
- Close relationships that are not obvious from their common names, such as limonene and perillyl alcohol
- Why isomers matter, and molecules that have (and don’t have) optical isomers
- Constituent profiles: carvone isomers, carvacrol, and thymol
Lesson 3 - Chemical Changes
- Overview of chemical changes that occur over the lifecycle of an essential oil: within the plant, on distillation, through storage, and on application to the body
- Explanation of degradation and catalysis
- Processes involved in chemical changes, including hydrolysis, reduction, and oxidation
- Constituent profiles: menthol, citral, and citronellal
Lesson 4 - Chemical Messages
- Molecular features that might influence biological effect
- Synergy versus antagonism, and the challenges of predicting effect
- The risks of extrapolation from constituent to whole essential oil, and the need for good clinical studies
- Constituent profiles: eugenol and methyl salicylate
When You Complete the Course
Fundamental Chemistry Certification
Essential oils are powerful health and wellness tools, and as such need to be treated with the respect they deserve. Your Certificate of Completion will be evidence that you understand the fundamental principles of essential oil chemistry.
What previous students say about our courses:
Ready to get started?
Will there be notes for me to review?
I am a certified aromatherapist. Will I learn anything new?
I am new to essential oils. Is this course for me?
“The information presented is appropriate for all levels, and although I am just beginning my aromatherapy journey it all makes sense.”
Will there be assessments or exams? What kind?
Each weekly lesson is followed by a multiple choice quiz, and there is a summary test at the end of each course. Passing both the weekly quizzes and the final tests is a requirement for certification.
You will be given enough time to prepare for the test as well as three attempts to pass.
Will I be able to ask questions?
Absolutely! In addition to the live Q&A sessions, you can post your questions in the dedicated student forums where the tutor and the TI team will address them.
What if I cannot participate on a live session?
All of our live sessions are recorded and are posted on the learning platform within 24 hours so you can watch them, or rewatch as needed during the course.
How long will I have access to the recordings?
You will have access to all the videos for at least four weeks weeks after the last lesson. All the printable materials (notes, handouts, charts, etc.) are of course yours to keep for reference forever.
Do you offer continuing education credits?
Because we have students from all over the world and of many professions we are not able to offer credits for specific organizations – there are simply too many. However, we issue a confirmation of CE hours gained on the course that you can apply with your professional organization and will be happy to assist with any additional documentation.
At the moment, we are an Approved Continuing Education Provider with NAHA.
