湿疹属于中医“湿疮”范畴,表现为皮肤湿烂、渗液、结痂,并伴有不同程度的瘙痒感,是一种慢性、复发性、炎症性皮肤病。中医认为,其发病以“湿邪”为核心,受环境、饮食等多方面影响。《严氏济生方》中的当归饮子主治“心血凝滞,内蕴风热,发见皮肤,遍身疮疥,或肿或痒,或脓水浸淫,或发赤”。当归饮子治疗血虚风燥型湿疹在临床应用广,疗效佳,并在中药汤剂的基础上,联合各种外治法,进一步提高临床疗效。又结合现代医学技术研究,对当归饮子治疗血虚风燥型湿疹的作用机制有了更深层次的认识。本文归纳了近年来当归饮子治疗血虚风燥型湿疹的相关研究报道,为进一步研究其作用机制和推广临床应用提供参考依据。

Eczema belongs to the category of “wet sores” in traditional Chinese medicine, characterized by damp skin, exudation, scabs, and varying degrees of itching. It is a chronic, recurrent, inflammatory skin disease. Traditional Chinese medicine believes that its pathogenesis is centered on “dampness”, and is affected by environmental factors, diet, and other factors. The Danggui Yinzi in Yan’s Jisheng Prescription is used for treating “heart and blood stasis, internal wind and heat, skin sores, swelling or itching, pus or redness”. Danggui Yinzi is widely used in clinical practice for treating eczema caused by blood deficiency and wind dryness, with good curative effect. On the basis of traditional Chinese medicine decoction, various external treatments are combined to further improve the clinical efficacy. Combined with modern medical technology research, the mechanism of action of Danggui Yinzi in treating eczema caused by blood deficiency and wind dryness has been further understood. This paper summarizes the relevant research reports on Danggui Yinzi in treating eczema caused by blood deficiency and wind dryness in recent years, providing a reference for further study of its mechanism of action and promotion of clinical application.
