Lot of things will kill candida fungus but the Iodine and borax are important for making sure it doesn't come back. It works slower but gets at the root of the problem. Not to mention they are dirt cheap.
Colloidal Silver
Turpentine
Kerosene ( pure kerosene 150-210 C boiling point, take in drop doses it is potent )
These are the best anti-fungals in my opinion. Pick one or more. Of course "Candida is always more than just candida there are a lot of different critters ruining our health.
Combine that with:
Good diet
Iodine
Borax
Ozonated water ( great for long term healing process )
Living away from densely populated areas with high EMF
