Candidiasis is an overgrowth of the common fungus known as candida. When candida overgrowth occurrs, getting rid of it can be challenging and time consuming. Although there are drug therapies for eliminating candida, many of them are beginning to lose their effectiveness to drug resistant strains of the fungus. There are many plant-based treatment options available, including pau d'arco, but using them effectively takes some perserverance and an understanding of how to use them.
