Jock ItchL Applied apple cider vinegar 2-3 times daily and took a 1oz shot twice daily for about two weeks. ACV relieved itchy sensation for a few hours when applied externally, but did nothing to reduce the problem. Taken internally it just rotted the enamel on my teeth.
It seems to work for sufferers of yeast infections, so possibly it depends on the strain of fungus or severity.
