Candida albicans is a yeast that is a normal inhabitant of the human body, usually without causing illness or discomfort. Only in people with suppressed or impaired immune systems, candida albicans may grow out of control. One of the most common manifestations of candidiasis is thrush, a white overgrowth in the mouth often found in patients who suffer from AIDS.

Candida overgrowth may also be a consequence of antibiotic treatment as antibiotics not only kill pathogens but also a large number of those bacteria that are part of a healthy gastrointestinal flora. Conventional pharmaceuticals in the treatment of yeast infections are the heavy-duty drug ketoconazole (Nizoral) as well as nystatin (Mycostatin).

A very potent alternative treatment of candidiasis and many other fungal infections is raw garlic. Acidophilus strengthens the immune system against yeast infections.
