What is a chemotype?
Chemotypes are variances of the chemical composition of certain essential oils extracted from one botanical species yet they vary in chemical compositions. They are not different species of the oil. Chemotypes occur when a plant produces a particular chemical in a higher than normal amount because of many environmental factors such as light, soil, temperature, moisture, climatic influence, altitude, insect activity, and geographic area.
Plants with different chemotypes: Rosemary, Thyme, Basil, Hyssop, and Niaouli. I will mostly be talking about Rosemary and Thyme for this blog post.
The three main chemotypes of Rosemary are camphor, cineole, and verbenone. Each has its own distinct aroma and therapeutic applications and safety.
Thyme has five chemotypes: linalool, gerianol, borneol, thymol, and thujanol-4. Each has its own distinct aroma and therapeutic applications and safety.
