The best and cheapest thing I have found to work for vaginal yeast infection (not sure if this is exactly what you meant) is boric acid. You can buy it in powder at the pharmacy, buy gelatin or veggie capsules size 0. Insert one capsule vaginally filled with boric acid every evening right before bed for seven nights. If it's really bad you may want to use one in the morning as well. And wear a panty liner, it somehow flushes you out and causes you to drip liquid all day long. But it works beautifully. Of course, if the candida is systemic, the infection may return quickly.
