Evaluation of the Anti-Fungal Activity of Clove and Cinnamon Essential Oils Against Candida albicans
Abstract
Fungal infections, particularly those caused by Candida albicans, pose a significant global health challenge, with rising incidences and emerging drug resistance complicating treatment strategies. This study investigates the antifungal potential of clove (Syzygium aromaticum) and cinnamon (Cinnamomum zeylanicum) essential oils against Candida albicans, focusing on their efficacy, mechanisms of action, and comparison with conventional antifungal agents. Phytochemical analysis revealed the presence of bioactive compounds such as eugenol and cinnamaldehyde in both oils, known for their antimicrobial properties. The antifungal activity was assessed using disk diffusion, minimum inhibitory concentration (MIC), and minimum fungicidal concentration (MFC) tests. Results showed that both essential oils exhibited strong antifungal effects, with cinnamon oil demonstrating slightly higher potency than clove oil, particularly at higher concentrations (100% and 75%). At lower concentrations (<50%), both oils lost efficacy. The study also explored the concentration-dependent nature of their antifungal activities, indicating that these oils could serve as promising alternative therapies, especially in the context of antifungal resistance. The findings highlights the potential of clove and cinnamon essential oils as cost-effective, natural antifungal agents that could contribute to more sustainable treatment options for Candida albicans-related infections. Further research into their mechanisms of action, including effects on biofilm formation and cell membrane integrity, is warranted.
