I have been undergoing radiation treatment for abdominal lymph nodes. I knew it could intensify my kidney stone pain. Now, a week after finishing my treatment the intense pain has subsided quite a bit. Chanca Piedra allowed me to get through treatment working within 30 minutes of feeling pain. I dosed 3x per day, once needing 4. Problem was that radiation affected my intestines and hydration- a huge contributor to pain with stones. I contribute my ability to weather this process to the supplement.
