I haven't used anything to break up the stones and very seldom use anything to soften them and have gotten over 20,000 stones out in the 25 flushes that I've done so far.
My girl friend is going to start liver flushing very soon and I plan on having her take both the chanca piedra and malic acid to make it as easy as possible on her and to ease her mind....she's a chicken like me.
