Introduction
Eczema is one of the most commonly seen dermatoses, especially among children. About 10 - 30% of the first-time patients seen in the department of dermatology are there for eczema. A commonly encountered allergic inflammatory dermatosis, eczema is characterized by polytypic erythra, symmetrically distributed exudation in the affected skin, intense itching, and liability to recurrence and to being turned into a chronic condition. In traditional Chinese medicine, it falls into the categories of "Yin" (urticcaria), "Xuan" (tinca), "Feng Zhong" (tinea corporis), "Jin Yin" (acute eczema), "Yin Chuang" or "Jin Yin Chuang" (acute eczema), "Shi Xuan" (exudative dermatitis) and "Gan Xuan" (chronic eczema).

Etiology/Pathogenesis
Eczema often results from exogenous wind, damp, and heat pathogens attacking interior damp-heat accumulated due to spleen dysfunction, which in turn is caused by improper diet, alcoholism, or excessive hot food, or seafood, etc. damaging the skin and muscles and leading to the onset of eczema. Alternatively, eczema may be caused by dampness-impaired spleen functions combined with malnourished skin and muscles in persons of congenital insufficiencies, or by unattended damp-heat accumulation, which impairs the blood and turns pathogenic dryness to pathogenic wind, leading to the onset of eczema.
