[ABSTRACT ] The TCM etiology and common differential patterns of various eczemas were discussed in conjunction with a brief review in western perspectives. Calming the Heart Shen as one of the TCM treatment principles for all patterns was put forward according to the Yellow Emperor’s Inner Classics. Treatment of Acupuncture and Herbal Medicine was provided according to the clinical experience of the author.
THE ECZEMAS, “Shi Zhen” in Chinese, are caused by endogenous or exogenous factors, characterized by papules, vesicles and exudation in acute stage and thickening & lichenification in chronic stages. Itching is almost always significant.
In western medicine, the terms eczemas and dermatitis are now used synonymously,therefore, the exogenous eczemas include contact dermatitis either due to skin irritation or allergies. The endogenous eczemas include atopic dermatitis, neurodermatitis, stasis dermatitis, etc.
Clinically, the eczemas are classified into acute or chronic eczemas.
The following features describe the acute eczemas:
a) Redness & swelling, usually with ill-defined margins
b) Papules, vesicles and more rarely large blisters
c) Exudation & cracking
The features of chronic eczemas are described as follows:
a) May show all above, though usually less vesicular & exudative
b) Thickening, lichenification, and dry leathery thickening with increased skin markings is secondary to rubbing & scratching (most often in atopic eczema)
c) Fissures & scratch marks
d) Pigmentation changes
In Traditional Chinese Medicine (TCM) the eczemas were commonly referred to as “Shi Chuang” (Damp Skin Sores) , however, there were other names documented according to the different locations of skin lesions, e. g. “ Si Wan Feng” (Four Bends Wind), “RuTouFeng” (Breast Nipples Wind), “XuanErChuan” (Around Ears Skin Sores). Some were also named according to the features of the skin lesions, e. g. “Niu Pi Xuan” (Cow Skin Lesion) which refers to lichenification in chronic eczemas as neurodermatitis, etc.
In my experience, the TCM etiology and common clinical patterns may be summarized as follows.
Wind-Damp-Heat pattern and Blood Heat pattern in acute stage and Damp-Heat pattern and Blood Deficiency in chronic stage. In all cases a factor that is present is disturbed Heart Shen. This was clearly stated in Yellow Emperor’s Inner Classics as “All painful or itching skin sores are part of the Heart Disturbances”. 
Therefore, the treatment principles for the eczemas are to dispel wind, remove dampness, clear heat, and cool the blood in acute stage. The treatment principles in the chronic stage are to nourish Yin& Blood, grasp wind, and calm the Heart Shen in all cases.
The acupuncture and herbal treatment are designed thereafter.
