I started to take a tea from GCG because I had very little a flush before and I also had some pains in GB/liver area. I wandered if that was a big stone sitting there and tested GCG. I don't think it actually breaks stones, most likely it activates the liver and may be enzymes start to work around stones making them weak and easy to break. I feel like there is something left there and may be flush in a 2 weeks.
