From Jeanne Rose Aromatherapy Studies Course “It is very difficult to describe an essential oil because they are not visible when in the plant. Essential oils are only visible as a liquid when they are released by some means such as distillation, CO2 extraction, or mechanical or a physical process. They are located in the plant, in glandular hairs or cells or scales; oil cells and resin cells; oil or resin canals; and oil reservoirs. They can be defined “as the scent of the plant in its liquid or vapor form.”…Jeanne Rose 1990
