AROMA 501 – Aromatherapy Science Course Introduction

Aromatherapy has become an increasingly popular modality to support wellness, particularly in an integrative healthcare setting due to its ability to enhance the quality of life for a wide range of clients. This graduate-level survey course provides students with an in-depth analysis of the fundamental principles of aromatherapy, aromatology, and aromacology. We will examine the major categories of aromatherapy, aromatology, and aromacology including definitions, selected proven and unproven effects of essential oils citing research literature, historical perspectives, essential oil constituents and bioactivity, the science of smell and psychological effects, safety issues, and clinical studies. Plant photographs for identification and interactive exercises help to bring the concepts to life for visually-oriented and kinesthetic learners.
