Itchy Skin

Also called:Itchy skinPruritusSkin itch

From the TCM perspective: TCM 'feng sao yang' (wind itch); located in skin, related to lung, spleen, liver and blood.

Overview

Itchy skin is an urge to scratch with or without marks or rash. The Zhubing Yuanhou Lun discusses 'wind itch'. TCM holds there is no itch without wind and that treating wind begins with treating blood; causes include wind-heat, damp-heat, blood deficiency generating wind-dryness, and damp-toxin lodged in the skin.

☯Common patterns (syndrome differentiation)

Wind-heat in the exterior

Key distinguishing signs: Intense itch worse with heat, red papules or wheals, fever, sore throat, red tongue tip, thin yellow coat, floating rapid pulse.
Treatment principle: Dispel wind, clear heat and stop itch

Damp-heat effusion

Key distinguishing signs: Itch with red patches, vesicles, oozing and erosion, often in folds or lower legs, sticky bitter taste, red tongue with yellow greasy coat, slippery rapid pulse.
Treatment principle: Clear heat, drain dampness, resolve toxin and stop itch

Blood deficiency with wind-dryness

Key distinguishing signs: Chronic dry scaly skin with scratch marks and crusts, worse at night and in autumn/winter, pale lusterless face, pale tongue, fine pulse.
Treatment principle: Nourish blood, moisten dryness and extinguish wind to stop itch

Damp-toxin accumulation

Key distinguishing signs: Recurrent itch with thickened skin, pigmentation or oozing/crusts, greasy coat, soggy pulse.
Treatment principle: Drain dampness, resolve toxin and stop itch

Daily self-care

Avoid scratching and very hot showers; bathe lukewarm and briefly, then apply fragrance-free moisturizer.
Wear loose breathable cotton and keep nails short; track suspected foods, medications or contact triggers.
With damp-heat keep skin folds dry; persistent generalized itch or itch with jaundice/weight loss needs medical work-up.

When to seek medical help

The following warning signs require prompt medical evaluation — do not rely on self-treatment:

Sudden whole-body hives with throat tightness, wheezing or swelling of face/lips/tongue: emergency (anaphylaxis).
Yellow skin/eyes, dark urine and generalized itch: promptly assess liver/biliary disease.
Rash with fever, large ruptured/oozing blisters, or spreading red-hot swelling: seek care promptly.
