The Stomach is closely related to the Large Intestine through the Bright Yang. Therefore the Heat normally co-exists in both Organs and it leads to dry mouth and dry tongue.
Finally, the Large Intestine is located in the Lower Burner and the Heat condenses the Body Fluids there, so that there is less urine and the color is rather dark.
