Picture of the EO Chem Oil Kit

The full chemistry of essential oils course comes with a 49 sample chemical kit in a convenient wooden box, course notes in a booklet, video access, quizzes and final test.

No extra book is required or included for this course.

This course is meant for those who have had some chemistry background or else are willing to do some self-study on their own to understand the fundamentals of very basic organic chemistry.


PREREQUISITE: All students must view the seven short videos in the following YouTube playlist: "Basic Organic Chemistry Primer"

Lecture Text Course Notes

If you have not watched the primer videos in the link above then DO NOT TAKE THIS COURSE. There will be no refunds so be sure that you are certain that this course is for you. The course can be started at any time, you only need to finish it within 12 weeks of receiving your kit in order to receive your certificate. Of course you can take as long as you want if you don't care about getting the EOU certificate. Thanks for your interest in the Chemistry of Essential Oils.

Course Content

The Chemistry of Essential Oils (part 1) will be concerned with the relevant chemistry concerning the naturally derived plant oils known as essential oils. Essential oils make up multi billion dollar industry mainly revolving around fragrances and flavors with growing interests in other areas for their medicinal properties.

The chemical constituents, methods of production, as well as uses in the above areas will be discussed. In addition to understanding lecture material students will be required to smell various essential oils and aroma chemicals and be able to identify them based on odor. The course is ideal introduction to anyone pursuing a career in the fragrance, flavor and cosmetic industries as well as for aromatherapy, alternative healing, and massage therapy.


There will be one exam graded by Dr. Pappas to determine pass/fail for the course. During the course there will also be 4 quizzes which the student will grade himself after being given access to the video discussion of the keys.

% Letter Description
90 - 100% A Completion with Highest Distinction
80 - 89% B Completion with High Distinction
70 - 79% C Completion with Distinction
60 - 69% D Completion
0 - 59% F No Certificate Given


If the student wishes to correlate his percent score on the exam with the grading system we use at Indiana University Southeast the grading scale below can be used for comparison. A score of 60% or better on the exam must be achieve to obtain a certificate of completion. There will be different certificate levels available, ranging from “Completion with High Distinction” to simply “Completion”, corresponding to the 4 levels of passing.

The Chemistry of Essential Oils Booklet is comprised of 44 pages of information concerning the Chemistry of Essential Oils. Whether you have a background in chemistry or not, this booklet will help you to understand the fascinating chemistry of essential oils.

Essential Oils are made up of organic molecules and can further be classified as terpenes, alcohols, esters, aldehydes, ketones, phenols, etc... By understanding the different compound classes, and what oils they appear in, you can determine the expected therapeutic properties of any particular oil.

The booklet comes in a concise 5" x 8" handy format, in full color.
