Candida is a type of yeast infection that can exist for several years in the body. It is extremely difficult to clear out of your system, even with prescription medication and antibiotics. According to the Candida Yeast Infection Relief website, Candida may be effectively eradicated by taking a daily freshwater diatomaceous earth supplement. Diatomaceous earth destroys the Candida yeast infection by pulling it apart and killing the Candida organisms that reside in the gastrointestinal system. In addition to being able to get rid of Candida yeast infections, diatomaceous earth is also known for its ability to attract and bind to the toxins that are caused by Candida yeast so the body can safely eliminate them through stool and urine.
