with Marco Valussi, BSc (Hons) Herbal Medicine and Benoit Roger, PhD
Integrating Knowledge into Power
There’s no substitute for knowledge and competency—the ability to evaluate and contextualize information. Without it, you have to trust the information you are given, with no way to actually use it creatively. With essential oils, the situation is even more critical, because there is often a lack of information on efficacy and safety.
Shape the Future
Few are willing to lead with a science-backed approach, and this is your time to shine. Taking this step signifies that you've undergone significant instruction, you understand both the pharmacology and therapeutic side of aromatherapy, and you're willing to guide others as a leading aromatherapy practitioner.
Elevate Your Expertise
This 5-module program explores the science, critical approaches, and methodology behind essential oil research. You’ll be introduced to the pharmacology of aromatic plants so you can interpret their therapeutic potentials. Apply pharmacological concepts to deepen your understanding of the properties and effects of essential oils on the human body, and understand the chemistry behind extraction, distillation, and quality of aromatic extracts.
