There does not seem to be an antifungal that can manage to kill rhizomic candida, perhaps simply because rhizomic candida is located in the sinus and bowels and the antifungals get carried about in the blood stream and do not reach there.
Anyhow, the ONLY thing that kills candida to our current knowledge, is the diet: starving it of what it feeds on: carbs (gluten) and sugar.
Finding which strain of candida will be indicative of the fungus present in your bloodstream, which perhaps shall reflect the strain of your candida that transformed into a rhizome, in your sinus and bowels, but perhaps it will not even be representative as severe candida allows for fungals to spread easily due to poor liver functions. So the fungals in your bloodstream might be different from the fungals colonizing your body.
