Just tell her not to be afraid. My biggest stone was 26mm and it wasn't painful nor I got rid it using any herbs. Strangely, few times smaller stones got stuck and with following mini LF'es or Epsom Salt doses- everythimg was fine. Even few parasites lost their free rent.
I very happy I am doing something amazing for my body and I am sure I am on the way to getting rid of all stones. Majority of them sit in a few jars in my freezer and that too help to visualize my progress.
Youor she can also drop me an email.
