you need to do a solid candida cleanse for at LEAST 120 days. This will wipe out pathogens causing BV. you want to take biofilm disruptors such as NAC as well as eat an alklaine diet (lots of veggies, low GI fruit, apple cider vinegar, grass-fed proteins, low starch) and you can also do a sitz bath with hydrogen peroxide or epsom salt bath.
BV wont improve unless you do a gut cleanse as what is where the infection is stemming from 🙂
