I did a couple of liver/gallbladder flushes about 6 months ago but ended up blacking out and going to the ER due to the large amount of fluid you lose and I guess I didn't drink enough. So I switched to herbs to break them. I have been taking chanca Piedra for 3 weeks and started feeling flu-like symptoms. Then... I passed some Gallstones so it DOES work!!! Foffie aol com.
