Native to North Africa, thyme grows in stony, rather dry soils. It is an example of a plant species that illustrates the concept of a chemotype. There are several chemical categories of thyme, in which the chemical composition of the essential oil varies depending on the biotype in which it develops. Factors that influence its composition and therapeutic activity include sunlight, altitude, soil type, and air quality.
