Damp-Heat invading the Spleen

Understanding Damp-Heat invading the Spleen

The Spleen is said to prefer dryness and to be damaged by Dampness. When Damp-Heat settles in it, the organ responsible for transforming food is itself obstructed, which is why the symptoms centre on the middle and on appetite.

The upper abdomen feels stuffy and full, often after small amounts of food. There may be nausea, a sticky or bitter taste, and loose or sticky stools.

The tongue is red with a thick yellow greasy coat in the centre and root, often swollen with teeth marks. The pulse is soggy and rapid, sometimes slippery.

It usually develops from rich, greasy, sweet or alcoholic food on top of a Spleen that was already weak, so it is a combination of excess and underlying deficiency.

Treatment clears Heat, drains Dampness and moves the middle, and diet is treated as central rather than optional. Tonics are avoided while the coat is thick.

Signs and symptoms

Key signs

• Stuffiness and fullness in the upper abdomen
• Poor appetite with nausea
• Yellow greasy tongue coating
• Soggy-rapid or slippery-rapid pulse

Also seen

• A sticky or bitter taste in the mouth
• A feeling of food sitting in the stomach
• Loose or sticky stools
• A heavy, muzzy head
• Tiredness after eating
• Thirst without much desire to drink

Variations

• Mouth ulcers
• Bad breath
• Belching with a sour or bitter taste

Timing

• Symptoms build after meals and worsen in humid weather.
• They ease when the diet is light for several days.

Practitioner notes

• The tongue is red with a thick yellow greasy coat thickest at the centre and root, often swollen with teeth marks.
• The pulse is soggy and rapid; a slippery quality adds Dampness.
• The distinction from Spleen Qi deficiency is the coat: deficiency is thin and pale, this pattern is thick and yellow.
• The distinction from Damp-Heat in Stomach and Spleen is emphasis: here the Spleen blockage with fatigue and loose stools is more prominent.

Causes

Common causes

• Alcohol consumption
• External Damp-Heat invading the body
• Emotional stress and overthinking
• Pre-existing Spleen weakness
• A sedentary lifestyle

How it develops

• It develops when Dampness that a weak Spleen failed to move becomes heated.
• If untreated, it can spread to the Liver and Gallbladder or to the skin.

Diagnosis

Diagnosis rests on the thick yellow greasy coat with middle-burner fullness and nausea.

Tongue

• Body: Red, often swollen with teeth marks.
• Coating: Thick, yellow and greasy at the centre and root.
• Note: A thin white coat would point to Spleen deficiency.

Pulse

Soggy, Rapid, Slippery

Soggy shows Dampness; rapid shows Heat.

Observation

• Oily skin
• A slightly distended upper abdomen
• A heavy bearing

Listening

• Belching
• A report of a sticky taste

Palpation

• Abdomen: Fullness and mild tenderness around the upper abdomen, without guarding.
• Channels: REN-12 and ST-25 may be tender; the abdomen may feel warm.

Questions that separate it from look-alikes

• Is there fullness or nausea after eating?
• How are the stools: sticky, loose or normal?
• How much alcohol and how much fried or sweet food?
• Is the mouth sticky or bitter?

Treatment

Principles

• Clear Heat
• Drain Dampness
• Move the middle and restore appetite
• Avoid tonics while the coat is thick

Herbs

Formulas

• Lian Po Yin - The reference formula for Damp-Heat in the Spleen and Stomach.
• Gan Lu Xiao Du Dan - For Damp-Heat with toxic swelling or infection.
• San Ren Tang - For Damp-Heat at the surface and in the middle with a muzzy head.
• Yin Chen Hao Tang - Used when the Damp-Heat has reached the Liver and Gallbladder with jaundice.
• Ban Xia Xie Xin Tang - For a mixed picture with nausea, fullness and Heat in the middle.
• Ping Wei San - A drying, moving formula for Dampness in the middle without pronounced Heat.

Acupoints

• REN-12 (Zhongwan) - The Stomach front-mu point, used for fullness, nausea and poor appetite.
• SP-4 (Gongsun) - The master point of the Chong vessel, used for middle-burner congestion.
• ST-25 (Tianshu) - Regulates the intestines and the stool.
• LI-11 (Quchi) - Clears Heat, useful when the Heat component is marked.

Personalising the plan

• If Heat dominates, cooling herbs are increased.
• If Dampness dominates, aromatic drying herbs are increased.
• If nausea dominates, descending herbs are added.
• If the Spleen is clearly weak underneath, gentle support is added without rich tonics.

Self-care

Diet

• Light plain food; small portions; avoid fried, greasy and sweet food
• Avoid alcohol while symptomatic
• Bitter greens and barley are traditionally used
• Warm water rather than iced drinks

Lifestyle

• Regular meal times, no late heavy meals
• Gentle walking after eating
• Keep the environment dry
• Reduce overthinking and stress

Qigong and movement

• Gentle walking and abdominal breathing after meals.

How it differs from look-alikes

Patterns that can be mistaken for damp-heat invading the spleen, and the contrast that separates them.

Where it appears

Skin conditions in which this pattern is commonly seen.

Safety and when to get help

For anything severe, sudden or spreading quickly, read when a skin problem needs urgent care.

This page describes a TCM pattern, not a diagnosis, and a pattern can accompany more than one skin condition. Get urgent medical help for a rash with fever, confusion or feeling very unwell; skin that is blistering, peeling or spreading quickly; swelling of the face, lips or throat, or difficulty breathing; or a lesion with increasing pain, warmth, red streaks or pus. For anything persistent, severe or changing, have it assessed by a clinician before treating it yourself.

Read the skin condition pages for the red flags that belong to a specific presentation.

Urgent-sign guidance is based on standard sources: NHS anaphylaxis, NHS cellulitis, NHS Stevens-Johnson syndrome, NHS melanoma.

Evidence note

No controlled trial of this treatment in skin conditions was identified for this entry. What is described here rests on the classical and later materia medica record and on traditional clinical use, not on controlled trial evidence, and it is not a prediction of benefit. Where skin-specific research does exist it is linked above.
