Aromatherapy Chemistry Online


The Aroma 507 Aromatherapy Chemistry course provides students with a systematic approach to learning the chemical functional groups and pharmacological actions of essential oils. Written by Joy Bowles, renowned author of The Chemistry of Aromatherapeutic Oils, this interactive, online, instructor-led course will help you to make sense of the chemistry of aromatherapy. This course is suitable for anyone who needs to understand the science and efficacy of this healing art, including: nurses, doctors, pharmacists, and other allied health practitioners.

The focus of the ACHS Aromatherapy Department is holistic aromatology. Holistic aromatology focuses on restoration of physical, mental, emotional, and spiritual health through the application of essential oils. We use the terms “aromatherapy” and “aromatology” interchangeably throughout the program. All healing modalities offered by ACHS focus on the holistic approach. Our philosophy is that only by taking care of the whole person, the physical, emotional, and spiritual, can health and wellness occur.
