Absinthe against multi-drug resistant bacterial pathogens? A recent update on the antibacterial effects of Artemisia compounds

Abstract

The widespread misuse of antibiotics leads to a rapid development of multi-drug resistant (MDR) bacterial pathogens all over the globe, resulting in serious difficulties when treating infectious diseases. Possible solutions are not limited to the development of novel synthetic antibiotics but extend to application of plant-derived products either alone or in combination with common antibiotics. The aim of this actual review was to survey the literature from the past 10 years regarding the antibacterial effects of distinct Artemisia species including Artemisia absinthiae constituting an integral component of the Absinthe drink. We further explored the synergistic antibacterial effects of the Artemisia plant products with established antibiotics. The survey portrays the Artemisia derived compounds as potent antibacterial agents that can even restore the efficacy of antibiotics against MDR bacteria, such as methicillin-resistant Staphylococcus aureus (MRSA) and MDR Escherichia coli. This, in turn, is presumably triggered in part by the interaction of the Artemisia ingredients with the efflux pumps of MDR bacteria. In conclusion, biologically active molecules in Artemisia plants enhance the antibiotic susceptibility of resistant bacteria, which provide promising future therapeutic strategies to combat MDR bacterial pathogens.
