Wow, that is so cool. I don't know much about iridology but I did find this:
Green indicates: The health of the myelin sheathing, which in this case, is adequate. But, since the autonomic nerve wreath (that which is highlighted in green) is so close to the pupil, this indicates that the person's colon contains insufficient fiber to keep the colon the circumference needed to maintain its health.
So, don't you think that it's interesting that your Mom had a green tint AND indigestion, and when the digestion issues started to go away, so did the green?
Hmmmm, sounds like some colon cleansing might be in order. I like Oxypowder myself. You can have a gentle or intense colon cleansing on it, and it is not habit forming. It is magnesium based, and literally melts fecal matter out of the small intestine. You can't even get up that far with a colonic. My best friend is an OB/GYN, and after turning her onto Oxypowder , she not tells her patients about it. Before Oxypowder , by friend was the queen of constipation.
