Plectranthus amboinicus; anti-infective properties; bacteria; carvacrol; cell wall components; cytotoxicity; reactive oxygen species; viability
Abstract:
... Carvacrol (5-isopropyl-2-methylphenol) is the major component of Plectranthus amboinicus. Several studies have shown that carvacrol has antibacterial, antifungal and insecticidal effects, but the mechanisms that govern these processes are unclear. Reactive oxygen species (ROS) play a major role in host defence eradication of microorganisms. In this study, we provide evidence that carvacrol has pri ...
