Beyond “lavender is relaxing” and “rosemary is stimulating,” what is the science behind the art and craft of aromatherapy? This class will delve into ambiguous labeling terms such as “therapeutic grade,” explain the meaning of chemotypes, explore countries of origin and their significance to the potency and chemical composition of the oils, and discuss methods of distillation and why this is important. Participants will smell a range of oils to gain a broader appreciation of the nuances of aromatherapy and make a personal inhaler to take home.
