There is a big misconception about mushrooms being bad for yeast infections because they are a fungus. Good bacteria-bad bacteria. Good fungus and bad fungus. Mushrooms are a friendly fungus that won't cause an increase in yeast growth. This is my opinion based on personal observation. Mushrooms are powerful antioxidants and boost the immune system. 70% of the immune system is in the intestines. Studies on the www.directfood.net/champex site state how the mushroom extract boosts the population of bifidus, and decreases the population of h.pylori and c.difficile. Therefore I contend that yeast cannot thrive in these friendly bacteria conditions. Do take a probiotic as well, though. And try the vaginal capsules called Femina Flora by New Roots. They are great.
