This study aimed to evaluate the antifungal efficacy of essential bark oil of Cinnamomum
zeylanicum against many pathogenic and non-pathogenic fungal strains. Essential oil was extracted
from the bark using the hydrodistillation method with a Clevenger apparatus and antifungal activity
was assessed by the plate diffusion technique. Results showed that C. zeylanicum essential bark oil
exhibited significant antifungal activity, suggesting its potential as a natural antifungal agent. These
findings indicated that the essential oil may serve as a promising candidate for broader applications,
warranting further evaluation of its efficacy and safety for human use.
