Abstract

Background: Oropharyngeal candidiasis is an important sign that may reflect a serious systemic disease, especially in immunocompromised patients who face the intolerable side effects of the available antifungal drugs. This necessitates the development of safe and effective natural components. Objectives: to evaluate the in vitro activities of both pomegranate peel and curcumin extracts and to compare them with nystatin and fluconazole drugs against Candida species. As far as we know, this is the first study comparing between the antifungal potency of both extracts. Methodology: Different Candida species were isolated from patients with oropharyngeal candidiasis. The antifungal activities of methanolic extracts of pomegranate peel and curcumin were tested by disc diffusion method. Both extracts were added to each of nystatin and fluconazole discs to measure their synergistic effects. Results: Highly significant synergism was detected between both extracts and each of antifungal drugs. Curcumin extract was more potent than pomegranate extract. Conclusion: When used in combination with nystatin and fluconazole, curcumin and pomegranate peel extracts are promising and effective anti-Candida agents.
