Damp-Heat in the Liver

Understanding Damp-Heat in the Liver

This is the Liver-channel version of Damp-Heat. The same pathogen shows in the channel's territory rather than the organ itself, which is why the signs follow the path of the channel down through the lower body.

The rib-side pain and distension are the upper end of the channel; the bitter taste and yellow greasy coat are the general Damp-Heat signs. Towards the lower end there is dark scanty urine and often genital itching or discharge.

The tongue is red with redder sides and a yellow greasy coat. The pulse is wiry, slippery and rapid.

It comes from alcohol and greasy spicy food, external Damp-Heat, Liver Qi stagnation that has heated, or Spleen weakness allowing Dampness to accumulate.

Treatment clears Heat and drains Dampness from the Liver channel, with a strong emphasis on the diet because alcohol is the most common driver.

Signs and symptoms

Key signs

• Pain and distension along the ribs
• Bitter taste in the mouth
• Yellow greasy tongue coating
• Dark yellow urine

Also seen

• Genital itching or discharge
• Irritability
• A heavy feeling in the lower body
• Nausea after fatty food
• A muzzy head
• Red eyes

Variations

• Burning on urination
• A bitter taste on waking
• Tenderness in the rib margin

Timing

• Symptoms are worse after alcohol and fatty meals.
• They flare in hot humid weather.

Practitioner notes

• The tongue is red with redder sides and a yellow greasy coat.
• The pulse is wiry, slippery and rapid.
• The distinction from Liver Fire is Dampness: Fire is dry and hot, this pattern is greasy and heavy.
• The distinction from Liver and Gallbladder Damp-Heat is emphasis: that pattern centres on the bile and hypochondrium, this one follows the channel into the lower body too.

Causes

Common causes

• Alcohol, greasy food and spicy food
• External Damp-Heat
• Liver Qi stagnation transforming into Damp-Heat
• Spleen weakness allowing Dampness to accumulate

How it develops

• It develops from prolonged dietary strain or untreated stagnation.
• If it worsens it can affect the bile and produce jaundice, or spread to the whole body.

Diagnosis

Diagnosis rests on the channel distribution of the signs plus a yellow greasy coat.

Tongue

• Body: Red with redder sides.
• Coating: Yellow and greasy.
• Note: A white greasy coat would indicate Cold-Damp.

Pulse

Wiry, Slippery, Rapid

Wiry is the Liver pulse; slippery and rapid add Dampness and Heat.

Observation

• Flushed face
• Possible yellow tinge to the eyes
• A heavy bearing

Listening

• A sharp tone
• A report of bitterness

Palpation

• Abdomen: Tenderness along the rib margins, sometimes with fullness.
• Channels: LR-8 and GB-24 may be tender; the lower abdomen may feel warm.

Questions that separate it from look-alikes

• Is there pain or distension along the ribs?
• Is there a bitter taste or dark urine?
• How much alcohol and fatty food?
• Any genital itching or discharge?

Treatment

Principles

• Clear Liver Heat
• Drain Dampness from the channel
• Free the Qi where there is distension
• Remove alcohol and greasy food

Herbs

Formulas

• Long Dan Xie Gan Tang - The reference formula for Damp-Heat in the Liver channel.
• Yin Chen Hao Tang - For Damp-Heat affecting the bile with jaundice.
• Da Chai Hu Tang - For right-sided pain with fullness and constipation.
• Wu Ling San - For fluid accumulation with difficult urination.

Acupoints

• LR-8 (Ququan) - The Liver channel point used for Damp-Heat in the lower body.
• GB-24 (Riyue) - The Gallbladder front-mu point, used for rib-side pain.
• BL-19 (Danshu) - The Gallbladder back-shu point.
• SP-9 (Yinlingquan) - Drains Dampness from the lower body.
• SJ-6 (Zhigou) - Used for rib-side and flank pain.

Personalising the plan

• If the lower-body signs dominate, draining herbs are increased.
• If rib-side pain dominates, Qi-moving herbs are increased.
• If jaundice is present, the jaundice herbs are increased and medical assessment is arranged.
• If the Spleen is weak, gentle support is added.

Self-care

Diet

• Light bland food; bitter greens and barley are traditionally used
• Stop alcohol completely while symptomatic
• Reduce fried, fatty and spicy food

Lifestyle

• Gentle regular exercise
• Keep the environment dry
• Manage frustration and stress
• Do not lie down immediately after eating

Qigong and movement

• Gentle movement with an emphasis on the ribs and the breath.

How it differs from look-alikes

Patterns that can be mistaken for damp-heat in the liver, 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.
