Dear Tutor,
I have two versions of possible answers. I hope that, may be, one of them can be correct
First version:
Through process of digesting, in which mainly stomach and spleen are involved, food is separating to the nutritive substances and wastes substances. Both the Spleen and Stomach are earth elements. Color of Earth is yellow. So the color of normal stool should be yellow.
Second version:
Color of normal stool is yellow because gallbladder helps digestion with its bile.
The bile is of a yellow, brown, or green color; it is secreted by the liver.
In jaundice, bile - instead of going by its normal way to the stomach - goes to the other parts of the body and gives them a yellow tint in color. Because in this case stomach lacks bile to digest food, the stool, which originate after separating food to clean and turbid as the end material, lacks yellow color. |
