The minimum inhibitory concentration (MIC) of this extract against MRSA was 19.5 μg mL1 and the corresponding minimum bactericidal concentration (MBC) was 39.0 μg mL1.
Conclusions: This study has scientifically validated the traditional use of Cinnamomum species in treatingwound infections. Of high scientific interest was the observation that the antibacterial effect of Cinnamomum impressicostatum stem-bark crude water extract against MRSA was significantly higher than its effect against MSSA, suggesting that the extract contains a compound(s) with higher specific neutralising activity against the drug resistance markers of MRSA.
