Beyond the Bottle: Understanding Essential Oils

by Petra Ratajc

Do you ever wonder if judging an essential oil’s quality or purity must involve some kind of superpower? Biologist Petra Ratajc is going to uncloak this mystery and pass this specialized ability on to you.

This four-part online certification course is a deep dive into how essential oils are made from the soil up. This is the complete journey from cultivation to cracking the lid on the bottle in your hand, with highlights on production, sustainability and quality control.

What is a flower wax? Should you grow your own lavender for home distillation? How do you really know what you’re getting when buying essential oils? How do you know if an essential oil has been adulterated, or has oxidized? And how can you make sensible, sustainable choices?

In this groundbreaking course, you’ll no longer be at the mercy of marketing that may not be accurate, or doesn’t address what you really need to know. Instead, you’ll learn about analyzing essential oils by decoding their growing conditions and plant biology, as well as their composition.
