Phenolic acids, a group of plant-derived compounds including caffeic acid, ferulic acid, and gallic acid, have attracted scientific interest for their potential antifungal properties. In vitro studies have demonstrated that several phenolic acids can inhibit the growth of pathogenic fungi such as Candida albicans, Aspergillus species, and Trichophyton species. The proposed mechanisms include disruption of fungal cell membranes, interference with cell wall synthesis, and inhibition of critical fungal enzymes. Some studies have also reported synergistic effects when phenolic acids are combined with conventional antifungal drugs, potentially enhancing their efficacy or reducing required dosages.

Despite these promising laboratory results, the clinical evidence supporting the use of phenolic acids for treating fungal infections in humans is currently limited. Most of the research remains at the preclinical level, with few animal studies and virtually no well-designed human clinical trials to confirm efficacy and safety. While phenolic acids are found in a variety of medicinal plants traditionally used for antimicrobial purposes, their direct use as isolated agents for fungal infections is not common in traditional medicine. Therefore, while the scientific basis exists at a preliminary level (hence a rating of 2/5), more rigorous clinical studies are needed before phenolic acids can be confidently recommended as treatments for fungal infections.
