Constipation in Traditional Chinese Medicine

In Traditional Chinese Medicine, constipation in the current formula set is particularly associated with Stomach Heat patterns. Differentiation still considers whether there is high fever, abdominal hardness, a dry yellow tongue coating, or milder heat with dry stools only. Classical formulas are matched to the degree and type of heat accumulation rather than to constipation as a single label. Accompanying signs such as tongue appearance, pulse quality and the presence of heat or cold help distinguish one presentation from another.

TCM Patterns Associated With Constipation

The same presentation may be understood through more than one pattern. Pattern differentiation weighs the accompanying signs, not the symptom on its own.

Pattern Common Features Related Formulas
Wind-Heat風熱證Exterior Patterns Fever that is more noticeable than chills, mild sweating, sore throat, thirst, and a cough that may be dry or with yellow phlegm. The onset is often abrupt after exposure to wind or heat. Nasal discharge can turn yellow, and the face may look flushed. Tongue tip red with a thin yellow coating; pulse floating and rapid.
Shaoyang Syndrome少陽證Exterior Patterns Alternating chills and fever, fullness and discomfort in the chest and rib-side, a bitter taste in the mouth, dry throat, dizziness, poor appetite and nausea, and an irritable or restless mood. Tongue with a thin white coating; pulse wiry.
Lung Heat肺熱證Heat Patterns Cough with yellow or sticky phlegm, thirst, a feeling of heat in the chest, and possible shortness of breath or flaring of the nostrils in stronger presentations. Fever may be present without marked chills, and the throat can feel sore or dry. Tongue red with a yellow coating; pulse rapid, possibly slippery.
Stomach Heat胃熱證Heat Patterns Burning or discomfort in the epigastrium, thirst with preference for cold drinks, bad breath, and a tendency toward constipation or dry stools. The gums may feel swollen or sore, and appetite can be strong yet unsettled. Tongue red with a yellow coating, possibly dry in the centre; pulse slippery and rapid.
Damp-Heat濕熱證Damp Patterns A heavy body with a sense of heat, sticky or bitter taste in the mouth, scanty dark urine, and discomfort that worsens in hot humid weather. There may be greasy skin, sticky stools, or yellowish discharge. Thirst is present but drinking may not feel satisfying. Tongue red with a yellow greasy coating; pulse slippery and rapid.
Food Stagnation食積證Stagnation Patterns Epigastric or abdominal fullness and distension after eating, foul belching or sour regurgitation, and reduced appetite for the next meal. Stools may be foul-smelling or sticky, and the person often feels better after vomiting or passing stool. Symptoms clearly relate to overeating or irregular meals. Tongue with a thick greasy coating; pulse slippery.
Blood Stasis血瘀證Stagnation Patterns Fixed, stabbing or piercing pain that does not move freely, often worse at night or with pressure. The complexion may look darker or purplish, and in women the menstrual flow can be dark with clots. Lips or nails may appear dusky. Tongue dark or with purple spots or congested veins under the tongue; pulse choppy or wiry and hesitant.
Blood Deficiency血虛證Deficiency Patterns A pale or sallow complexion, dry hair or skin, light-headedness on standing, blurred vision, and easy fatigue. In women the menstrual flow is often scanty and pale. Sleep may be light, and the hands and feet can feel numb when tired. Tongue pale and thin; pulse thin and weak.
Yang Deficiency陽虛證Deficiency Patterns Aversion to cold, cold limbs, preference for warm drinks and clothing, and low energy that worsens in cold weather. There may be loose stools, clear copious urine, a pale puffy face, and reduced libido or lumbar weakness. The person feels better with warmth and worse with cold exposure. Tongue pale and possibly swollen with a white coating; pulse deep and weak.
Yin Deficiency陰虛證Deficiency Patterns Dry mouth and throat, night sweats or warm palms and soles, a thin body frame, and restlessness that is worse in the afternoon or at night. Sleep may be light, and there is often a preference for cool drinks. Symptoms feel empty rather than forceful. Tongue red with scant coating; pulse thin and rapid.

Frequently Asked Questions

How does Traditional Chinese Medicine understand constipation?
In TCM, constipation (便秘) is mainly related to impaired transmission of the Large Intestine. Heat drying the fluids, Qi stagnation slowing movement, Qi or Yang deficiency failing to propel, or Blood and Yin deficiency failing to moisten the intestines can all lead to dry, hard or infrequent stools. The Lung and Spleen also influence Large Intestine function.
What are the common TCM patterns of constipation?
Frequent patterns include Heat accumulating in the intestines (dry hard stools, thirst, bad breath), Qi stagnation (urge without smooth passage, worse with stress), Qi deficiency (straining with soft stools, fatigue), Yang deficiency (cold abdomen, difficulty passing even soft stools), and Blood or Yin deficiency (dry stools in thin or elderly people). Accurate pattern differentiation determines the treatment approach.
How does TCM regulate constipation?
The main principles are to clear Heat and moisten, move Qi, tonify Qi or Yang, or nourish Blood and Yin according to the pattern. Formulas such as modifications of Ma Zi Ren Wan, Liu Mo Tang, Huang Qi Tang or Run Chang Wan may be considered. Diet, hydration and bowel habits are equally important. Internal treatment should be guided by a qualified TCM practitioner.
