Damp-Phlegm

Understanding Damp-Phlegm

The tradition treats Phlegm and Dampness as stages of the same problem. Dampness is fluid that has become sluggish; Phlegm is the thicker, more congealed form that results when it is left to settle.

The Spleen is the source. When its transforming function is weak, fluid accumulates rather than being distributed, and that accumulation becomes Dampness and then Phlegm.

The signs are heavy rather than hot: copious white phlegm that is easy to bring up, a heavy body, fullness in the chest and upper abdomen, a muzzy head, and sometimes dizziness. The tongue is pale, swollen and teeth-marked with a thick white greasy coat.

On the skin, Damp-Phlegm produces swellings that are soft, pale and slow to resolve, and a boggy or doughy quality to the tissues. It is the opposite of the red, hot lesions of Damp-Heat.

Treatment dries Dampness, transforms Phlegm and strengthens the Spleen, because without supporting the Spleen the Phlegm simply re-forms.

Signs and symptoms

Key signs

• Copious white phlegm that is easy to cough up
• Heaviness in the body and limbs
• Chest and upper abdominal stuffiness or fullness
• Thick white greasy tongue coating

Also seen

• A muzzy head or a feeling of fog
• Dizziness, often with nausea
• Poor appetite and a feeling of fullness after small meals
• Soft or sticky stools
• Sleepiness after eating
• A pale, puffy appearance
• Soft, slow-healing swellings on the skin

Variations

• Palpitations with a heavy chest
• Numbness in the limbs
• A sensation of a lump in the throat
• Puffiness around the eyes

Timing

• Symptoms are worse in the morning and after rich meals, and better after light activity.
• Damp weather makes the heaviness and muzziness worse.

Practitioner notes

• The tongue is pale and swollen with teeth marks and a thick white greasy coat, and the surface looks wet.
• The pulse is slippery or wiry-slippery, and often slow rather than rapid.
• The distinction from Phlegm-Heat is colour and temperature: here the phlegm is white and the tongue pale, with no yellow coat.
• The distinction from Spleen Qi deficiency is the coat: deficiency has a thin coat, Damp-Phlegm has a thick greasy one.

Causes

Common causes

• Weak digestive function, especially Spleen Qi deficiency
• Living or working in damp environments
• A sedentary lifestyle
• Emotional strain and overthinking
• Invasion of external Cold-Dampness

How it develops

• It develops from long-standing Dampness that has thickened.
• If Heat is added, it becomes Phlegm-Heat, with yellow phlegm and a yellow coat.

Diagnosis

Diagnosis centres on the tongue coat and on the quality of the phlegm and the heaviness.

Tongue

• Body: Pale, swollen and teeth-marked, wet-looking.
• Coating: Thick, white and greasy.
• Note: A yellow coat would indicate Phlegm-Heat instead.

Pulse

Slippery, Slow, Wiry

Slippery is the classic Phlegm pulse; slow points away from Heat.

Observation

• Pale, puffy appearance
• A heavy way of moving
• Soft swellings if the skin is involved

Listening

• A loose, rattling cough if the Lungs are involved

Palpation

• Abdomen: Fullness and mild tenderness around the middle, without guarding.
• Channels: The tissues may feel doughy; ST-40 and REN-9 may be sensitive.

Questions that separate it from look-alikes

• What colour is the phlegm, and is it easy to cough up?
• Is there heaviness, muzziness or dizziness?
• How is the appetite, and is there fullness after eating?
• How much dairy, fried food and raw food?

Treatment

Principles

• Dry Dampness
• Transform Phlegm
• Strengthen the Spleen so that Phlegm does not re-form
• Move Qi so that the chest and middle are not congested

Herbs

Formulas

• Er Chen Tang - The reference formula for Damp-Phlegm: two herbs to transform Phlegm and two to support the middle.
• Liu Jun Zi Tang - The Spleen-tonifying base with Phlegm-transforming herbs, for the pattern with clear deficiency.
• Ban Xia Bai Zhu Tian Ma Tang - For Damp-Phlegm with dizziness and a muzzy head.
• Ping Wei San - A drying, moving formula for Dampness settled in the middle.
• San Zi Yang Qin Tang - For Phlegm and food stagnation with cough and fullness, often used in older people.
• Di Tan Tang - For stubborn Phlegm with dizziness and palpitations.

Acupoints

• ST-36 (Zusanli) - Builds Spleen Qi, the root treatment for Damp-Phlegm.
• SP-6 (Sanyinjiao) - Drains Dampness and supports the Spleen.
• REN-9 (Shuifen) - The point for regulating fluids, used for Dampness and oedema.
• LU-7 (Lieque) - Opens the Lungs and is used for phlegm and chest congestion.

Personalising the plan

• If deficiency dominates, Spleen support is increased.
• If the chest is congested, Qi-moving and Lung-opening herbs are added.
• If dizziness is marked, herbs that settle the head are added.
• If Heat appears, cooling herbs are added and the pattern becomes Phlegm-Heat.

Self-care

Diet

• Warm, cooked, lightly spiced food
• Barley, turnip and small amounts of ginger are traditionally used
• Reduce dairy, fried food, sugar and raw cold food
• Smaller meals more often rather than large ones

Lifestyle

• Regular gentle exercise, which is the most effective way to move Dampness
• Avoid damp living and working environments
• Do not lie down immediately after eating
• Keep warm and dry

Qigong and movement

• Regular gentle practice, focusing on the breath and the middle of the body.

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.
