White Tongue Coating

How Chinese medicine reads a white tongue coating into the 6 patterns behind it — including a classical Greater Yang cold-attack stage — and the points for each. Distinct from this site's own Coated Tongue page. Acupuncture only — no herbs.

A tongue sign is one piece of a larger picture and should be read alongside the rest of the presentation by a qualified practitioner.
General Acupuncture Points

Acupuncture points traditionally used for a white tongue coating — 3 key points, used across the patterns below rather than tied to just one.

PointKey action
ST-36Benefits Stomach and Spleen. Tonifies Qi and Blood. Tonifies the Original Qi.
LU-7Promotes the descending and diffusing of Lung-Qi. Releases the Exterior and expels exterior Wind. Opens the Directing Vessel.
BL-20Tonifies Spleen and Stomach. Resolves Dampness. Regulates the Intestines.
The Six Patterns

↑ reinforcing   ↓ reducing   ⊥ even method.

1. Wind-Cold View full pattern →

Clinical manifestations: A strong aversion to cold, no sweating, headache and body aches, nasal congestion with clear discharge, no thirst.
Tongue: Normal or slightly pale, thin white moist coating. Pulse: Floating and tight.
Treatment principle: Warmth and light sweating open the pores and expel the pathogen.

2. Greater Yang Attack of Cold

Clinical manifestations: Intense chills and shivering, no sweating even with fever, generalized body aches especially in the neck and back, headache.
Tongue: Normal, thin white moist coating. Pulse: Floating and tight across all positions.
Treatment principle: Release the exterior with warmth and a light sweat to expel the strong cold invasion.
Note: Confirmed absent again: this classical Shang Han Lun stage is new to the site, joining last batch's Greater Yang Accumulation of Water — no deck slide names it.

3. Damp-Cold View full pattern →

Clinical manifestations: A thick white greasy coating, heaviness in the body and limbs, loose stools or diarrhea, cold hands and feet, poor appetite with bloating and nausea.
Tongue: Pale, swollen, teeth-marked with thick white greasy excessively moist coating. Pulse: Deep, slow, slippery.
Treatment principle: Warmth helps the Spleen transform Dampness while gentle movement lifts the heavy stagnation.

4. Spleen Yang Deficiency View full pattern →

Clinical manifestations: A thick white moist or slippery coating, a pale puffy tongue with scalloped edges, easily feeling cold, dull abdominal pain relieved by warmth, loose watery stools with undigested food.
Tongue: Pale, puffy, tender with scalloped teeth marks, white slippery coating. Pulse: Deep, slow, weak, the Guan position especially empty.
Treatment principle: Warmth provides the heat the Spleen cannot generate on its own, helping steam away the Dampness.

5. Damp-Phlegm

Clinical manifestations: A thick white greasy coating, copious white phlegm that is easily expectorated, heaviness in the body and limbs, chest and upper-abdominal stuffiness, poor appetite and nausea, dizziness or brain fog.
Tongue: Pale, swollen with scalloped teeth marks, thick white greasy coating, wet surface. Pulse: Slippery, possibly soggy in the right Guan.
Treatment principle: A weak Spleen cannot transform fluids, so turbid Dampness congeals into Phlegm.
Note: Confirmed absent again: standalone Damp-Phlegm has no matching deck slide on this site.

6. Dry-Cold

Clinical manifestations: A thin white dry coating, chills stronger than fever, a dry cough with little or no phlegm, a dry scratchy throat, no sweating.
Tongue: Pale, thin white dry coating. Pulse: Floating and tight, strongest at the Cun position.
Treatment principle: Cold constricts and dryness injures the fluids; warm fluids gently release the exterior while moistening the Lung.
Note: Confirmed absent again: this classical Dry-Cold pattern has no matching deck slide on this site.
