It is well known that antimicrobial resistance represents today a major public health problem, and aside the minimization of the unnecessary prescribing or over prescribing of antibiotics, the investigation of complementary and appropriate infection control procedures represents an interesting therapeutic opportunity. Among the alternative strategies to those involving conventional sanitizing agents, the use of essential oils (EO) represents an experimental frontier in terms of safety, efficacy and patient’s compliance to antimicrobial treatments. The EO antimicrobial capacity have been extensively evaluated by several in vitro studies, which established their inhibitory activity against pathogenic bacteria, fungi, molds and yeasts [1].
