A MIRACLE. This is a probiotic supplement. It is used to balance out the natural flora "down there". Anyone with chronic yeast infections, BV, or UTI's will benefit immensely. This stuff does what no conventional treatment is able to do...cure the problem and prevent recurrence. If you are curious, look up the reviews on Amazon. This product is saving women from months of suffering. I used it myself and found it 100% effective, after visiting doctors for a year with no result. If you are having any feminine issues down below, you MUST do yourself a favor and buy this. I don't work for the company...I am just trying to help other women out there! :) PS--It needs to stay refrigerated, so buy it at Whole Foods or, if online, from a retailer that ships it with an icepack.
