The stones are always bright green in color and range from a little larger than a cranberry to small like a lentil or even the head of a pin.
Does the bright green color mean they're newer?
An interesting note is that after I got my dental clean up done (Huggin's protocol), I'm getting A LOT more stones out than I did before. I'm only a little less sensitive to grain now, but still have a great deal of trouble with carbohydrates. I am a VERY CLEAN eater. I have to be EXTREMELY careful...so do my three kids.
