I can offer my experience for your consideration. I was diagnosed with gall stones in March. I had been having horrible headaches, which I attributed to menopause. I had been having them for two years. Mine would cycle every 3 or 4 days. The pain was so intense that I felt like doing nothing. These headaches would grip the back of my head and go up to my eyes and brow and would not let go. It felt like my muscles in the neck area were steel cables that were winched up to the max. Well, enough description. I have been working on clearing these stones with herbs and I have done one liver flush. After I did the one flush two weeks ago, I got releif from the headaches. I haven't had one in the past two weeks. This is a record for me. There has been no other change really in my habits since the headaches stopped. Good luck to you and your daughter.
