Abstract
The global concern regarding the occurrence of antifungal resistance to synthetic conventional azoles used for treating vulvovaginal candidiasis, along with the associated side effects, is significant. Consequently, the pursuit for substitutes such as natural therapies has ensued. Essential oils, derived from plants, have been extensively researched and found to possess antibacterial and antifungal properties. This study aimed to assess the antifungal efficacy of two essential oils, both alone and in combination, against Candida albicans. Essential oils were formulated into an emulgel separately and as combinations. The essential oils of Melaleuca alternifolia and Cymbopogon flexuosus were used in this study. The resulting emulgel formulations were characterized for their antifungal activity against Candida albicans. Physiochemical properties such as pH, viscosity, and appearance were also determined. The prepared emulgels were thereafter observed for stability over a period of 1 month. The MIC of Melaleuca alternifolia was seen to be 50 µL/mL while Cymbopogon flexuous was seen to be more potent at 25 µL/mL against C. albicans exhibiting strong synergistic effect at 0.4. The emulgel formed was white in color, smooth on skin, and had the odor of the essential oils, which is sweet to the nose. The pH of the formulations with the essential oils were acidic in the range of 3.70–3.83, making them suitable for vagina application. The emulgels had viscosities ranging from 4417.6 to 8968.7 mPas, owing to the thickness of the essential oils contained. The emulgel formulation with the combination of essential oils was more potent that the two with individual essential oils; furthermore, the one with Cymbopogon flexuous was more potent than the one with Melaleuca alternifolia. Based on the properties of the formulated emulgels and their activity against the test organism, the preparations have significant potential in the management of vulvovaginal candidiasis.
