Thymes are relatives of the oregano genus "Origanum". "Origanum syriacum" is native to the Middle East. It is extracted from Origanum oil by means of a 50% potash solution. "Origanum syriacum" grows to a height of 1 meter. It has also been identified in "Origanum onites", a plant related to oregano. It can be found in "Origanum vulgare" and in "Ariocarpus retusus". "Origanum libanoticum" is hardy and has good heat and drought tolerance. The enzyme from oregano ("Origanum vulgare") gives mainly bicyclogermacrene with Mn as a cofactor. Oregano ("Origanum vulgare"), sometimes listed with marjoram as "O. majorana", is also called wild marjoram. The related species, "Origanum onites" (Greece, Turkey) and "O. syriacum" (West Asia), have similar flavours. The larvae feed on "Plantago", "Achillea", "Calluna", "Origanum", "Thymus" and "Solidago".
