Raw material. Thyme was harvested during the flowering season (July 2012) from the area around the Broşteni commune – Mehedinţi County, Romania. The plant material was dried in well-ventilated areas, sheltered from direct sunlight and then stored in double-layered paper bags at temperatures of 3-5°C until processing. A voucher specimen (V.FPT-451) was deposited in the Herbarium of the Faculty of Pharmacy, “Victor Babeș” University of Medicine and Pharmacy, Timișoara, Romania.
