That's funny - there is pretty convincing evidence that candida is is killed by sodium bicarbonate. That comes from a medical doctor in Italy who is experimenting with it "outside the box".
I find it odd to see somebody advising to use wine vinegar for anything but cleaning rust off of metal.
A lot of things will kill Candida if directly applied. This does not mean it will do the same thing in the body. Sodium bicarbonate if taken orally will not even remain as sodium bicarbonate very long as it will react with acids in the digestive system converting in to salts. Very basic chemistry!
