Traditional Chinese medicine believes that eczema is often caused by improper diet, alcoholism or excessive consumption of spicy and stimulating food, which damages the spleen and stomach, and dysfunction of spleen in transport, resulting in the endoretention of damp heat, and the exopathogenic pathogenic wind -dampness and pathogenic heat. Soaked skin causes this disease.
Or because the body is weak, spleen deficiency with dampness retention, and the failure of skin and muscle to be nourished. Or due to the dampness -heat stagnating for a long time, the yin and blood are consumed, and transforming dryness into wind, resulting in blood deficiency and wind-dryness, and the squamous and dry skin. In conclusion, the etiology of eczema is very complex, which is the result of the interaction of many internal and external factors.
中医认为，湿疹常因饮食失节、嗜酒或过食辛辣刺激的食品，伤及脾胃，脾失健运，致使湿热内蕴，又外感风湿热邪
或因身体虚弱，脾为湿困，肌肤失养。或因湿热蕴久，耗伤阴血，化燥生风，而致血虚风燥，肌肤甲错。总之，湿疮的病因非常复杂，为多种内外因素相互作用的结果。
