From the TCM perspective: Itching: wind-dryness, damp-heat or blood deficiency generating wind
Overview
Skin itching provokes scratching, with or without a rash. TCM distinguishes acute wind-heat/damp-heat (redness, papules, oozing) from chronic blood-deficiency wind-dryness or yin deficiency (dry scaly skin worse at night, often in the elderly).

2
Damp-heat with oozing
Key distinguishing signs
Itching with vesicles, oozing fluid and yellow crusts, greasy tongue coat and rapid slippery pulse

3
