I was told this exact thing by a holistic practitioner a few years ago and I know it works 100% for BV!!
Aloe in Unsweetened Cranberry Juice
I just wanted to add in regard to BV, I had it a couple of years ago and it was recurrent no matter what my Dr. gave me. Finally, I ask a friend of mines who is well versed with natural cures what I should do and she simply said, "2tbsp of natural aloe vera to 8oz of unsweetened cranberry juice. Not only does it get rid of the BV, I have also found that it works well with balder infections. Pray this helps someone as it did me.
