Cranberries contain phytochemicals called proanthocyanidins which have both antibacterial and antifungal properties. A number of earlier studies have reported that consumption of cranberries or cranberry juice is associated with cure of several types of bacterial urinary tract infections. Cranberries may also be useful for treating fungal (mold) infections as well. 


Hallie Rane et al. Cranberry derived proanthocyanidins prevent formation of Candida albicans biofilms in artificial urine through biofilm- and adherence-specific mechanisms. Journal of Antimicrobial Chemotherapy 2013; In Press.

A lab study reported that a cranberry extract containing proantocyanidins was very effective in reducing growth and biofilm formation of Candida albicans in an artificial urine. Candida albicans is a common mold which commonly lives in human digestive and urinary tracts. Production of biofilms by Candida can increase the virulence and severity of Candida infections. (Biofilms involve growth of fungi and/or bacteria on surfaces which are anchored by proteins or carbohydrate polymers produced by the fungi or bacteria.)
