The thyme is a wild plant naturally present in the Syrian Seaside at varying altitudes up to more than 1000 m above sea level. The essential oil was extracted from thyme plants taken from seven sites (Safita - Beit Sheikh Younis, Khirbet Al-Mezah – Albirdanie, Sheikh Badr – Aljalsat, Banias – Shibani, Qadmous – Alhatria, Qardahah - Deir Hanna, Albhloulih - Beit Alia) by distilling 200 g of dry leaves from each site to obtain the essential oil.
