Tanning bed, bake the shit out of it, longer the better, I'm sure sunlight will do the job just as well or better but that's the miracle for me, I've had jock itch for a year and tried everything under the sun except the sun until one day it rang a bell to me that sunlight kills fungus, then eat acidophilus, if the bottle says a serving size is 1 capsule, eat 25 A day, it won't hurt ya, it's just a probiotic so if anything it's just gonna boost your immune system...your doing that because you probably have an overload of Candida in your system and it may be an internal problem creating an external problem, stay away from Antibiotics , drink lots of water
