Advanced Graduate Program
Continue to hone your skill by learning advanced chemistry that supports therapeutic blending. You’ll practice using GC/MS reports as a decision-making tool, learn a variety of advanced blending techniques, and gain familiarity with a number of lesser-known essential oils.

Inside the course
Welcome & Orientation
12 lessons
Meet your instructors, gather your supplies, and learn your way around the Component Database before the chemistry begins. The safety information in this orientation is the foundation for every blend you make in the program.
Module 1: Basic Chemistry and Monoterpenes
21 lessons
Begin with the atoms themselves: how carbon, hydrogen, and oxygen bond to build the components in your oils. Then meet the monoterpenes, practice reading a GC/MS report, and blend with d-limonene, the pinenes, and beta-myrcene.
Module 2: Isomers, Sesquiterpenes and Carriers
11 lessons
Isomers explain how two molecules with the same formula can act so differently, and the sesquiterpenes show how a heavier molecule shapes shelf life and therapeutic action. Carrier oils and butters complete the module, and you finish by making a skin healing butter of your own.
Module 3: Monoterpenols and Sesquiterpenols
16 lessons
The alcohols come next: monoterpenols such as linalool and geraniol, and sesquiterpenols such as carotol, the molecule that leads cultivated carrot seed oil. You will learn to read a functional group, blend a hand gel and a salt scrub, and find your way through published research.
Module 4: Phenols and Ethers
12 lessons
Phenols such as thymol and carvacrol, and ethers such as methyl eugenol, are among the most potent molecules on your shelf. This module shows you how to choose a concentration/dilution for them and puts them to work in a cold and flu lotion.
Module 5: Aldehydes, Ketones and Esters
21 lessons
Aldehydes, ketones, and esters each carry their own safety considerations, and May Chang, Eucalyptus dives, and Petitgrain show you each family in a bottle. Along the way you will learn how preservatives, antioxidants, and dispersants keep a water-based blend stable, and practice blending several oils at once.
Module 6: Oxides, Plant Families and Plant Parts
13 lessons
The oxides, led by 1,8-cineole in Myrtle, Saro, and Niaouli, are the family most often reached for in respiratory blends, and this module includes our guidance on using them with children. From there you step back to see the whole shelf: component structures, plant families, and plant parts as three more ways to choose an oil.
Module 7: Hydrolats
9 lessons
Seven hydrosols for clinical and hospice care, from the still to the client's room: how a hydrosol is made and kept, and where each one belongs on the skin, in the mouth, and in the air.
Module 8: The Clinical Lessons
23 lessons
Aromatherapy beside the medical team: the hospital, the medication review, pregnancy and birth, children, care homes, cancer treatment and hospice, with recipes built on this course's own oils.
Your Case Studies
8 lessons
Everything you need for your six client case studies is here: the guidelines, the intake and report forms, the safety guidelines and release form, and a complete worked example from one client's intake through three reports.
Assessments
6 lessons
The final exam draws on every module. Pass it, complete your case studies, and your certificate follows, along with a short survey and a look at where your studies can lead next.
