Aromatherapy Science - AROMA 501

Aromatherapy Science
Course Number

Aromatherapy has become an increasingly popular modality in complementary and alternative medicine (CAM), particularly in an integrated medical setting due to its ability to enhance 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 perspective, essential oil components and bioactivity, the science of smell and psychological effects, safety issues and clinical studies. Plant photographs and interactive exercises help to bring the concepts to life for visually-oriented and kinesthetic learners.
