i have no idea, nor do you. that lancet article was about one woman, not me and not you. and since i saw my mother in law's stones, and know she didn't take oil... i know her green/yellow globs were not formed by the process described in the article. as yet, you have provided no explanation for this case, probably because it does not fit your theory. so, if lancet is wrong about one case, what else was missed.
i also don't doubt people who have posted results of their own chemical analysis... cholestol, bile ect. to you, they must be lying because such a result does not fit your theory. same for the red stones, black stones, ect.
and of course, this debate does not even concern the benefits which you dismiss as subjective, unproven ect. Thankfully i put all that aside when i flushed... and flushed away my chronic problems. thankfully I am not a scientist, but rather someone who just wanted to get well, and made it thanks to curezone.
