Brittle, Pale, or Ridged Nails

How Chinese medicine differentiates brittle, pale, or ridged nails into the five patterns you'll actually meet in practice, and the points for each. Distinct from this site's own Purple Nails page. Acupuncture only — no herbs.

This page is educational, for practitioners and students — it is not a diagnostic tool and does not replace a proper in-person assessment. Nail changes are one diagnostic sign among many — always weigh them alongside the tongue, pulse, symptoms, and history, and rule out iron deficiency, thyroid disease, or another medical cause first.

The Five Patterns

1. Liver Blood Deficiency View full pattern →

Clinical manifestations: Brittle, ridged nails, dry eyes or blurred vision, muscle cramps or tingling limbs, scanty, pale, or late periods, dizziness or light-headedness.
Tongue: Pale body (especially at the sides), thin and slightly dry with thin white coating. Pulse: Fine and choppy, possibly wiry at the left middle position.
Treatment principle: Blood fails to reach the fingertips and moisten the nail beds.
Note: moxa applicable on ST-36. Direct exact-name match with this site's own Liver-Blood-deficiency slide.

2. Blood Deficiency

Clinical manifestations: Brittle, ridged nails, pale or sallow complexion, pale lips, dizziness, heart palpitations or feeling faint, scanty, pale, or late periods, poor memory.
Tongue: Pale, thin body with thin white coating. Pulse: Fine, weak, thready — barely perceptible.
Treatment principle: The body lacks sufficient Blood to nourish the extremities.
Note: moxa applicable on ST-36/BL-20/REN-4. This site has no organ-nonspecific Blood-deficiency slide on any deck — no pattern link is given here; points still link fine individually.

3. Liver Blood and Kidney Yin Deficiency View full pattern →

Clinical manifestations: Brittle, ridged nails, dry eyes or blurred vision, lower back and knee soreness or weakness, night sweats, scanty, pale, or late periods.
Tongue: Red or pale-red, thin body with little or no coating, possibly cracked and dry. Pulse: Fine and weak, wiry at the left middle (Liver) position, weak at the left rear (Kidney) position.
Treatment principle: The nails lack both nourishment and moisture, so dryness sets in, leading to ridges, dullness, and cracking.
Note: no moxa. Linked to this site's own Kidney-and-Liver-Yin-deficiency slide, the closest match, with this pattern's Liver-Blood (rather than pure Liver-Yin) framing flagged as a minor nuance.

4. Liver Yin Deficiency View full pattern →

Clinical manifestations: Dry eyes or blurred vision, night sweats, irritability and restlessness, heat in the palms, soles, and chest, dull ache under the ribs.
Tongue: Red, thin body with redder sides, dry surface, little or no coating. Pulse: Wiry, fine, and rapid.
Treatment principle: Depleted Liver-Yin causes the nails to lose their gloss and flexibility, becoming dry, brittle, and dull.
Note: no moxa. Direct exact-name match with this site's own Liver-Yin-deficiency slide.

5. Kidney Yin Deficiency View full pattern →

Clinical manifestations: Brittle, ridged nails, lower back and knee soreness or weakness, night sweats, heat in the palms, soles, and chest, dry mouth and throat especially at night, tinnitus or dizziness.
Tongue: Red, thin body with little or no coating, dry surface, possible cracks. Pulse: Fine and rapid, especially weak at the left rear (Kidney) position.
Treatment principle: Depleted Kidney-Yin causes the nails to lose moisture, becoming brittle, dry, and ridged, much like a riverbed cracking in a drought.
Note: no moxa. Direct exact-name match with this site's own Kidney-Yin-deficiency slide.
