I fell out of an attic, bouncing on my behind from 8' in the air. Within hours there were what I recognize as gallstones in my toilet. I'd had NO olive oil or epsom salts that day ... I flush with grapefruit juice, not the lemon juice drink that I have for breakfast.
My mother had gallbladder surgery. They gave her gallstones in a medicine bottle. The stones that I passed in flushing were like the stones she had removed from her body.
There is a file of liver photos in the images section here. Disected livers and gallbladder full of green stones. Reckon the drs made them with grapefruit juice, olive oil and epsom salts for the pictures???
