The Large Intestine's main function is to absorb fluids so as to form and excrete stools. This can be greatly disturbed due to the Dampness in the Organ. As a result, fluids can not be absorbed properly and diarrhoea happens. Dampness can also be reflected by the mucus in the stools. feeling of heaviness, abdominal fullness and pain, a sticky tongue coating and Slippery pulse. Finally, fever, which doesn't disappear by sweating, might also occur due to Dampness. Please be aware that fever usually happens only for severe cases.

If there are Heat in the Large Intestine, blood in the stools can happen as the Blood gets rebellious and leaks out of vessels due to excessive Heat. In additional to that, awfully stool smell, anus burning, thirst, dark urine, fever, red tongue and Rapid pulse are also the signs of Heat pattern.

Depending on if Heat or Dampness predominates for a case, the symptoms of both patterns can vary greatly. Sometimes the patients only have symptoms of one pattern such as the Heat. Then that is the other pattern of Heat in the Large Intestine.
