Home remedies for candidiasis (thrush) include the consumption or direct application of yogurt (which contains lactobacillus), probiotics, acidophilus tablets or salves, and even lightly crushed cloves of garlic, which yield allicin, an antifungal agent. Boric acid has also been used to treat yeast infections (by inserting gelcaps filled with boric acid powder into the vagina at bedtime for three to four consecutive nights). Eating a diet consisting primarily of green, fresh, raw vegetables also may give relief.
Alternative treatment for Candidiasis for those interested in a more holistic approach would be to consume a fermented beverage that is very similar in taste and texture to "drinkable yogurt" called Kefir.
