Can candida be cured safely and how?

Fungal infection: depending on the location and the treatment being used

Yes, if it's real: Candida infection on the mouth, groin, private parts, skin folds is familiar and is easily managed with today's medications. Deep candida infections in immunocompromised people require strong Rx. The "pop" diagnosis "candida overgrowth" is a myth; people who buy into it never feel well again but keep spending money on worthless treatments. Best wishes.
