Brittle, Pale, or Ridged Nails

How Chinese medicine differentiates brittle, pale, or ridged nails, the five patterns you'll actually meet in practice, and the points for each. 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 alongside unexplained weight loss, or a single discolored streak on one nail, need medical evaluation before assuming it is a simple nutritional/pattern issue.
General Acupuncture Points

Acupuncture points traditionally used for brittle, pale, or ridged nails — 7 key points, used across the patterns below rather than tied to just one.

The Five Patterns

↑ reinforcing   ↓ reducing   ⊥ even method.

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 the sides, thin and slightly dry with thin white coating. Pulse: Fine and choppy, possibly wiry at left middle.
Treatment principle: Nourish Liver Blood and regulate blood circulation.
Note: moxa applicable on tonifying points. Direct match — the deck slide explicitly lists dry hair and pale complexion among its symptoms.

2. Blood Deficiency

Clinical manifestations: Brittle, ridged nails, pale or sallow complexion, pale lips, dizziness or light-headedness, heart palpitations or feeling faint, poor memory, difficulty concentrating.
Tongue: Pale, thin body with a thin white coating. Pulse: Fine, weak, and thready — often barely perceptible.
Treatment principle: Restore the body's core Blood supply.
Note: moxa applicable throughout. No deck on this site has a plain, organ-nonspecific Blood-deficiency slide, so no pattern link is given here.

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, often wiry at left middle and weak at left rear.
Treatment principle: Nourish both Liver Blood and Kidney Yin.
Note: no moxa. This site's Kidney- and Liver-Yin deficiency slide is the closest match — dry eyes, lower back/knee soreness and night sweats are named there, though that slide doesn't specify a separate Liver-Blood component.

4. Liver Yin Deficiency View full pattern →

Clinical manifestations: Dry eyes or blurred vision, night sweats, irritability and restlessness, heat in 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: Nourish Liver Yin to restore cooling, moistening energy.
Note: no moxa. Direct name match with this site's own Liver-Yin deficiency slide, first use of this specific slide.

5. Kidney Yin Deficiency View full pattern →

Clinical manifestations: Brittle, ridged nails, lower back and knee soreness or weakness, night sweats, five-palm heat, dry mouth and throat, ringing in the ears or dizziness.
Tongue: Red, thin body with little or no coating, dry surface, possible cracks. Pulse: Fine and rapid, especially weak at left rear.
Treatment principle: Nourish Kidney Yin and Essence to restore deep cooling and moistening reserves.
Note: no moxa. Night sweats and five-palm heat are the same Empty-Heat markers named on this site's Kidney-Yin/Empty-Heat slide, so it links there rather than the plain Kidney-Yin deficiency slide.
