I have been brewing it and drinking it daily for a while now with great success. Although I don't have many OB's these days, I did have the beginning of one a few months ago after I moved to a new climate and started swimming in the ocean every day and such things (without always showering WOOPS).
I put a piece of the kombucha on it and it was gone in 2 days! No joke!
I believe in a holistic approach and have a lot of other protocol in place, but I have never had sores go away that quickly before! And even though I do not get many OB's, I sometimes get that itchiness *before and OB. But since I started drinking the Kombucha every day, even the itchiness has gone away. (knock on wood)
I urge anyone having issues to start brewing your own kombucha and drinking it every day!
