Large intestine damp-heat syndromes

Abdominal pain, dysentery or stool containing blood and pus, tenesmus, burning sensations of the anus, scanty and yellowish urine, yellow and sticky tongue coating, wiry, slippery and rapid pulse.

The retention of damp-heat in the large intestine causes a dysfunction of qi activity with resulting abdominal pain and tenesmus. Damp-heat injures the qi and blood of the intestinal tract, so dysentery, or bloody and purulent stool occur. Burning sensation of the anus is a characteristic manifestation of "downward pouring of damp-heat into the large intestine." Scanty yellowish urine, yellow sticky tongue coating, and wiry, slippery, and rapid pulse are signs of internal retention of damp-heat.

Large intestine fluid exhaustion

Constipation, difficult defecation of dry stools, dryness of the mouth and throat, red tongue proper with a yellow dry coating and a thready or rough pulse are all signs of fluid consumption.
