That is your proof?......you cut into a stone and found what you say is chocolate, and it smelled like oil?......that is your proof?....did you chemically test the chocolate?.......
Since you used the oil to make your gallbladder squeeze the stones out....there is a perfectly good reason why the stones would smell like oil....duh?????
As to the chocolate......I found a link to pics of stones that were cut in half and the center of them is very dark...some are dark green, and some are black in the center.....according to your theory, the person who passed these stones must have eaten chocolate, as you did, at the same time that they did the flush.....if they did not eat chocolate, then why are the center of the stones black?
Also, why would you title your thread "proof that green balls are not gallstones"...when you obviously only smelled and looked at the stones without any other testing....
