The pharmacological active genus Thymus L. comprises over 200 species. Besides its traditional pharmacological use, thyme may reduce the risk of caries disease, however, there is very little respective literature. The pharmacological effects can be attributed to the secondary plant metabolites. The composition of the essential oil and the polyphenols is important for the evaluation of the pharmacological activity. Nevertheless, there are no studies regarding a comparative analysis of the different pharmacological thyme species...

Infectious diseases caused by pathogens and food poisoning caused by spoilage microorganisms are threatening human health all over the world. The efficacies of some antimicrobial agents, which are currently used to extend shelf-life and increase the safety of food products in food industry and to inhibit disease-causing microorganisms in medicine, have been weakened by microbial resistance. Therefore, new antimicrobial agents that could overcome this resistance need to be discovered. Many spices-such as clove, oregano, thyme, cinnamon, and cumin-possessed significant antibacterial and antifungal activities against food spoilage bacteria like Bacillus subtilis and Pseudomonas fluorescens, pathogens like Staphylococcus aureus and Vibrio parahaemolyticus, harmful fungi like Aspergillus flavus, even antibiotic resistant microorganisms such as methicillin resistant Staphylococcus aureus...
