I just used ACV for external discomfort, not as a douche, though I've heard that works, as well. The Tea Tree Oil tampon with coconut oil worked like magic for me. Yeast HATES Tea Tree, and coconut. I did these TTO tampons for three days and had no further signs of yeast. Drinking homemade kefir kept me yeast-free after my last round of Antibiotics and I'm still not having any candida symptoms (thank GOD). But I'm also taking magnesium, which I believe is the final step in curing systemic yeast infestations.

You can take ACV internally, as well, but when I did it I took too much and had an absolutely HORRIBLE herxheimer effect. I was sick for the rest of the day. Felt much better a day later, and had some pretty serious nastiness come out of me. I could literally feel it purging and then it came out...huge nests of yeast. I really don't recommend this method because I thought I was dying the die-off was so severe. Oh, and I also took Coconut Oil, too. A good way to kill yeast, but not the best way to do it! LOL

I would not recommend any other vinegar than ACV with the Mother for douching if you have candida issues. ACV is the only vinegar that will make your body's PH levels alkaline...and yeast thrives in acidity.
