I do not know if this helps with yeast infections, but one great thing that helps with blatter issues and cleaning the inside parts related to this is cranbarries. If you can't/don't want to dink it they make great pills for this too. I have fond high doses of Cranbarry pills at walgreens that has high doses of vitmin C and E so this is a great way to boost your emmune system while cleaning out the urinary track. I have had multiple urinary, bladder, and kidney infections in my life and I know the cranberry works!!!
