Anal Irritation (Pruritus Ani)

How Chinese medicine differentiates anal irritation and itching, the three 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. Bleeding, a visible lesion, or symptoms that don't respond to basic hygiene measures need medical evaluation before assuming it is a simple pattern.
General Acupuncture Points

Acupuncture points traditionally used for anal irritation — 5 key points, used across the patterns below rather than tied to just one.

PointKey action
DU-1Local point directly clearing Damp-Heat, regulates the two lower orifices.
SP-9Drains Dampness from the Lower Burner.
SP-6Strengthens Spleen, harmonizes the lower body, nourishes Blood and Yin.

The Three Patterns

↑ reinforcing   ↓ reducing   ⊥ even method.

1. Damp-Heat in the Lower Burner View full pattern →

Clinical manifestations: Anal redness with oozing, intense burning sensation, dark scanty urine, worse in warm/humid weather and after spicy/greasy foods.
Tongue: Red body, slightly swollen, with a yellow greasy coating thickest at the root. Pulse: Slippery and rapid, more pronounced at the rear.
Treatment principle: Clear heat and drain dampness from the Lower Burner.
Note: no moxa. Direct match with this site's own Damp-Heat in the Bladder slide on the Lower Burner organ-system level.

2. Blood Deficiency with External Wind

Clinical manifestations: Dry, scaly, flaking anal skin; itching worse at night or in dry conditions; pale/sallow complexion; dizziness; sensitivity to drafts.
Tongue: Pale, thin body with a thin white and slightly dry coating. Pulse: Fine, often wiry at left middle, possibly floating at right front.
Treatment principle: Nourish Blood and moisten dryness while dispersing invading Wind.
Note: moxa applicable on the tonifying points. This site's Liver-Blood deficiency slide has no Wind component, so no pattern link is given here — same absence found for Seborrheic Dermatitis, Athlete's Foot and Fungal Skin Infection.

3. Spleen Deficiency with Dampness

Clinical manifestations: Moist, oozing anal skin without strong redness; dull itching; thickened skin; abdominal bloating and loose stools; poor appetite; fatigue after meals.
Tongue: Pale, swollen body with teeth marks, white greasy coating, moist surface. Pulse: Soggy and slow, soft and lacking force.
Treatment principle: Strengthen the Spleen's transformative function to prevent fluid seepage into anal tissues.
Note: moxa applicable on the tonifying points. No deck on this site combines Spleen deficiency with Dampness in one slide, so no pattern link is given here.
