At no time have I said that because you have a white tongue that you have intestinal candidiasis, let alone systemic candidiasis (which you most certainly do not have). I have simply advised you to treat your white tongue with a topical antifungal to find out whether it is infected by Candida. This is useful to know, especially if you later develop other symptoms indicating intestinal candidiasis. So many people here are treating candidiasis when they don't really know for certain they have it, let alone which antifungals their strain of Candida is susceptible to.
I have found that testing antifungals on my white tongue to be VERY useful in determining which antifungals my intestinal Candida infection is susceptible to.
