Call those green things blobs or stones they don't just soften but dissolve completely in freshly pressed apple juice. I have been experimenting with mine, they dissolve. Try it yourself or ask anyone you trust to try to dissolve their blobs in fresh pressed juice.
Ressurrectionist may refer to different medical articles and human bile ducts observation, but it seems like he has not done any flush and that really makes it difficult to discuss the matter with him.
So far the idea that they are coming from liver (and some from gallbladder) makes the most sence to me. Too many questions remain unanswered to support any other theory.
Anything can be dangerous for one or another under sertain circumstances, but so far there are millions of people who flushed liver successfully with great health improvement. Some people report no results, unsucessful flush etc. There is no one procedure that would feet everyone.
As for what else you should know, read FAQ on curezone. There are a lot of helpful posts there.
