oh you now concede that at least some blobs are not gallstones. in fact the green blobs were very like the green blobs described by many people.
the way in which you use the term PRCT suggests you do not understand the uses of the PRCT. a PRCT would be used to assess an intervention, not to determine whether green blobs are Gallstones or not.
I very much doubt medics would get much joy with a study to look at the products of the liver flush. would you volunteer?
