Citrocept (grapefruit extract) works perfect against candida, I have it at home and use it as soon as candida attacks me. It usually takes about three days to fix it.
If you have discomfort in your vagina because of candida, Clarkia helps it quite good when applied locally. If you delute it to light tea colour with clean water and do vaginal douche it will reduce the symptoms significantly.
But the previous post was right about candida's constant stay in our bodies. We just have to keep it under control by healthy Diet and by avoiding too much stress.
