Testimonials

This was the first time I felt I could grasp any part of chemistry, so many, many thanks! 3D models were crucial for understanding concepts. Really helpful to apply to EO deeper understanding and chemical constituents I see again and again. Only thing I’d like is to see a 3D tinker toy demo of a chemical reaction in action between molecules, to see exactly how electrons are exchanged, shared, lost, double bonds are broken, etc. (maybe two people needed for the interactive exercise!)

I would just like to thank Robert and Hana for making EO training available to all.

I appreciated the passion that was put into the course. I stumbled across this by chance and I am so thankful I did. This has expanded my passion and knowledge about formulations. It has enhanced my learning about essential oils. I just want to thank you for offering this course and all that you do. I feel so confident having your institute as my education platform. I am a beginner but feel confident with your amazing education that it wont be long before I am a pro!!

I found it to be inspiring! Whilst being very informative and in depth, I was constantly engaged and wanted to do more. I am a level 3 Aromatherapist in the UK and doing this course made me appreciate how much more there is to learn and know and makes me want to learn more and more! It is such a huge subject and there is a lot of misinformation around. The teaching level here makes me confident that I am being given the correct information and learning at the highest level. Thank you. I am looking forward to the next course.

Good introduction to essential oils. Enjoyed learning about the growth of plants, distillation, and evaluation of the oils. Information was presented efficiently and clearly.
