Stonehedge,
I haven't tried coptis yet. The GCG isn't exactly tasty so I can't imagine the coptis. Does it help? Maybe I'll try it after I finish the GCG. I can't get over how quickly the GCG has relieved the pressure in my gallbladder.
Did you find the GCG helpful in breaking up stones? I'm hoping I can get my calcified stone out after two bottles, but it's worth getting rid of the pressure feeling even if it doesn't dissolve/break the stones enough.
