I would recommend you try coconut oil 2-3 tablespoons a day (the 1st week and add 1T week 2 - up to 7T daily is therapeutic dose, 4T daily is maintenance, a great
anti-fungal agent which may work better than
anti-fungal medications.). It is also antiviral, antiparasitic and antimicrobial.
Look up Oil Pulling with coconut oil for improving oral hygiene and health.
I have been doing this every morning for years using extra virgin organic coconut oil.
