Check out Julia Chang's website: (www.sensiblehealth.com) on her recommendations for using "Gold Coin Grass" and "Curcuma" for dissolving large stones before flushes. I am taking these two herbs besides the "Chinese Bitters" before I do my FIRST FLUSH. Her website has many wonderful recommendations and lots of information on liver and gallbladder flushes, besides helpful and enlightening information on other related health problems that I have. Hopefully, this will answer your question.
Thank you for sharing your experiences, as I need all the encouragement and support I can find.
