h202 will help but not cure... lol... I use h202 in everything now. It cleans the toilet better than bleach does. Try this... put some h202 in the toilet bowl, and then put the scrubber in the toilet bowl aswell. Watch how much the scrubber and toilet fizzes... makes you wonder how effective bleach really is.
Aswell h202 will help, but it will not cure anything. Only a contextual approach to candida will work. If you over use h202 you will only hurt yourself... because it oxidises... which is good... because it can help you if a symptom flares up a bit. But if you over use it... you can damage the area that your are applying it to... because the candida will keep on coming back, and the afflicted area will not get a chance to heal.
