Thyme (Thymus vulgaris
) is an evergreen herb from the mint family. It has been used for culinary, medicinal, ornamental and folk medicine uses since ancient times, and in a variety of different cultures. Thyme has an herbaceous and slightly floral aroma. It loses its aroma quickly with heat. Thyme is used in fresh and dried form, a whole sprig (a single stem snipped from the plant), and as an essential oil extracted from the plant parts. Volatile oils of thyme are among the main essential oils used in the food industry and in cosmetics as preservatives and antioxidants. Thyme contains several beneficial bioactive chemicals, with the most important being thymol.
: Thyme oil shows potential for improvement of intestinal barrier integrity, antioxidant status as well as evoking an immune response in chickens.
Thyme essential oil has been proven in many experiments to be highly antibacterial and antifungal when tested on Gram positive and Gram negative bacteria, fungi and yeasts, due to its thymol and carvacrol content. Thyme oil and thymol decreased the growth of Salmonella typhimurium
in vitro, particularly under anaerobic conditions.
: 100 ppm of thyme can help improve body weight and feed conversion ratio in chickens.
