Nowadaysthe conventional treatment of Candida infections requires the use of azoles (clotrimazolefluconazoleitraconazoleketoconazole)polyenes (amphotericin Bnystatin) and echinocandins [23]. Howeverdifferent strains of various Candida species are developing resistant mechanisms to the treatment with these drugs [14]. In additionconventional antifungal drugs often show toxic side effects to human cells [56]. Based on these considerationsresearchers’ efforts in developing novel approaches to improve the effective treatment of fungal infection is growingwith a renewed interest in plants and traditional medicine. In this fieldincreasing attention has been paid to essential oils (EOs) as promising natural compounds for their different activitiessuch as antibacterialantifungalantiviralantioxidantanticancerimmune-modulatoryanalgesic and anti-inflammatory [78]. It has been reported that their broad-spectrum activity against a variety of microorganisms is probably due to the alteration of the membrane and cell wall of microorganismswith consequent loss of cytoplasmic material [9]. EOs pharmacological activitiesmainly related to their complex chemical composition and high concentrations of phenolsmake these compounds particularly interesting for both the treatment and the prevention of candidiasis [8101112].1860 More details Edition11(5) Internal reference1860 Open publication →
