I Have been dealing with hemorrhoids and colon cleansing for a while -mainly by using dietary measures and coffee enemas, with some success. But recently I still got a lot of itchiness and was wondering whether I had yeast infections or not. I tried grapefruit seed extract as a home remedy as mentioned in quite a helpful site on yeast infections, and felt some difference but I am impatient for change so went to see a naturopath today. He said rather than pay for a candida test (which you could order online apparently) I should make an appointmnent and he would do a urine test and other tests to identify properly what was causing the itchiness. So I agree with the comment that you should confirm the presence of a yeast infection first, before going to expense taking different things.
