Since 1985,  the Pacific Institute of Aromatherapy has offered high-level study materials, examination and certification by correspondence to enthusiasts all over the world.

The Aromatherapy Course is authored by Kurt Schnaubelt, PhD and comprises over 350 pages of clearly presented information on the most relevant topics in the field of aromatherapy. The goal is to become deeply familiar with genuine and authentic essential oils so the student is empowered to create the most effective therapeutic formulae. 

Prior editions were exclusively based on scientific French style aromatherapy with authors Pierre Franchomme and Daniel Pénoël (l’aromathérapie exactement) working with Dr. Schnaubelt to develop the application protocols.

The 4th Edition remains rooted in the scientific French approach yet explores additional contemporary viewpoints: Biology explaining how evolutionary advantages lead to healing properties, California style blending and Chinese Medical Aromatherapy healing strategies.
