The genus Stachys is one of the largest genera of the Lamiaceae family, and contains about 300 species worldwide and represented by 72 species in the flora of Turkey. Also, Stachys annua subsp. annua var. annua is widely used in Turkey and among the local people the species known as "dağ çayı". Herbal tea prepared by the method of infusion with the leaves of this plant is used in traditional medicine for colds and diabetes. In addition, it has been used as an antipyretic in Anatolia for many years. The rich essential oil components contained within the plant add a pleasant smell to herbal teas and diterpenoids are an important component of essential oil. In this study, the volatile components of the Stachys annua subsp. annua var. annua plants were investigated which collected from the Anzer (1533 m) and Cimil (1750 m) plateau of Rize at the time of flowering. The proportion of essential oils of the plant harvested during the full flowering period and the aromatic components in the essential oil of the plant were determined using the SPME (Solid Phase Microextraction) method in a Gas Chromatography (GC-MS) device. Almost 30 different components were found as a result of the analysis. The main components were found as germacrene-D (18.82%) and camphor (13.82%) in Anzer plateau and germacrene-D (25.2%) and camphor (13.82%) in Cimil plateau.
