The patient
- Age and sex
- 31 years · F
- Chief complaint
- A 31-year-old woman with scaly plaques in the elbow and knee creases since childhood, now flaring with intense itching, worse at night and during stressful periods.
- Tongue
- Red, dry, narrow body with a redder tip and scant coating.
- Pulse
- Thin and rapid pulse, wiry (Xian) at the left Guan (關).
Symptoms
- Intense itching, worse on lying down and with bed warmth
- Dry, thickened, cracked skin between flares
- During flares, redness and oozing in scratched areas
- Flares coincide with tense periods and poor sleep
- Sleep broken by night-time scratching
- Dry mouth in the morning and somewhat dry stools
Warning signs to rule out
- Lesions with yellow crusts, pus, increasing pain or fever. → Medical assessment: superinfected eczema needs antibiotic treatment and does not wait.
- An extensive, very painful flare with clustered vesicles, especially with a history of herpes. → Urgent assessment for possible eczema herpeticum, a serious complication with a deceptive appearance.
- The patient proposes stopping her topical steroid on her own. → She should discuss it with her dermatologist. Abrupt withdrawal causes rebound, and that decision does not belong in the acupuncture clinic.
Case resolution
Think through the pattern first, then expand the resolution
- Pattern
- Blood Heat with Blood dryness generating Wind, on a background of Yin vacuity
- Meridians involved
- Lung, Liver, Spleen
- Pathogenic factors
- Blood Heat, Blood dryness, Internal Wind
Itching is Wind, and in a chronic picture that Wind does not come from outside: the Blood itself generates it after years of being dry and hot. Thickened, cracked skin between flares is Blood that no longer nourishes; redness and oozing during flares is Heat surfacing. The nocturnal worsening fits the same mechanism, since at night Yin should contain the heat and here it falls short. Treating only the flare with cold herbs relieves for days and dries the terrain further.
Differential diagnosis
Shares: Red, intensely itchy lesions during flares.
Sets it apart: In Damp-Heat there are vesicles and copious, persistent oozing, with a yellow greasy coating and a slippery pulse. Here oozing appears only where she scratches and the underlying skin is dry: nourish rather than drain.
Shares: Dry, thickened skin and nocturnal itching.
Sets it apart: In pure vacuity there is no redness even during flares, the tongue is pale and the pulse thin without rapidity. Here the tongue is red and the pulse rapid: there is heat as well as dryness, and purely nourishing formulas fall short.
Shares: Itchy plaques appearing in flares.
Sets it apart: Contact dermatitis respects a sharp border tracing the exposed area and appears with exposure, not with stress. A flexural distribution since childhood points to atopic eczema.
Treatment
Principle: During flares, cool the Blood and dispel Wind. Between flares, nourish Blood and Yin so the skin stops generating Wind.
| Point | Role | Technique |
|---|---|---|
| SP10 | Sea of Blood: the dermatological reference point; it cools and moves Blood. | Perpendicular 1-1.5 cun, reducing during flares and even technique outside them. |
| LI11 | Large Intestine He-sea: it cools the Heat surfacing in the skin. | Perpendicular 1-1.5 cun, reducing, mainly in the acute phase. |
| SP6 | Nourishes Blood and Yin: the axis of the dry phase, between flares. | Perpendicular 1-1.5 cun, tonifying. Contraindicated in pregnancy. |
| LU5 | Lung He-sea; the Lung governs the skin, so it cools from the organ in charge. | Perpendicular 0.5-0.8 cun, reducing. |
| LV3 | Releases the Liver, the route by which the stress that triggers each flare enters. | Perpendicular 0.5-0.8 cun. |
| HT7 | Calms the Shen: nocturnal itching breaks sleep and broken sleep worsens the itching. | Perpendicular 0.3-0.5 cun. |
Formula: Xiao Feng San. Dispels Wind and cools Blood during flares with intense itching. Between flares, with dry, thickened skin, Dang Gui Yin Zi nourishes Blood and stops itching without drying further.
- Frequency
- Two sessions weekly during flares and one weekly in the dry phase, over a three-month horizon. Skin is slow: itching improves in weeks and appearance takes months, and that is worth saying before starting.
Home care
- Emollient twice a day, including when the skin looks fine: the highest-impact measure on this list.
- Short, lukewarm showers, patting dry and applying cream while the skin is still damp.
- Short nails and light cotton in bed; night scratching keeps the cycle going.
- Remove alcohol, spicy food and shellfish during flares, which heat the Blood in this pattern.
Progress
- Session 1 · active flare Red plaques on both elbows with scratch excoriations, itching 8 out of 10 and three nightly awakenings. SP10, LI11 and LU5 with reducing technique, plus HT7 for sleep. The emollient is prescribed and the steroid from her dermatologist is continued. Night itching drops to 5 out of 10 within ten days and she sleeps through four nights out of seven.
- Session 4 · week 3, flare resolved No redness, but the skin in the creases is dry, thickened and still itchy at night. LI11 is dropped and the approach moves to nourishing with SP6 and SP10 in even technique, with Dang Gui Yin Zi. Continuing to cool here would dry further. The dryness improves over four weeks and the background itch drops to 2 out of 10.
- Session 8 · week 8 A mild flare coinciding with a week of work assessments, limited to one elbow. Two cooling sessions and reinforcement of LV3. The emotional trigger is addressed, as relevant here as the skin itself. The flare resolves in five days, against the usual three weeks.
- Session 12 · month 3 Supple skin without cracks, with occasional itching. Her dermatologist has stepped down the steroid potency. Maintenance moves to monthly and consistency with the emollient is reinforced, as it is the first thing to be dropped. Two mild flares over the following six months, against one every six weeks before.
- Discharge
- Treatment ends after two months without a flare and with skin that stays supple on the emollient. In atopic skin the goal is not cure but flares that are rare, short and manageable.
- Watch for relapses
- Winter, with heating and hot showers, and tense periods. The first warning is night itching with no visible lesion, two or three nights before the plaque appears.
