血热型银屑病的中医外治法研究进展

中医学认为银屑病的病因病机是营血亏损，化燥生风，复感风热毒邪，导致肌肤失养。不少医家运用中医学理论对其进行分型论治，将银屑病主要分为血虚型、血瘀型及血热型。血热型银屑病相当于银屑病的进行期，是银屑病病程中的重要阶段，若治疗不当，滥用药物，有可能使机体自稳状态失去平衡，病情可能暂时得到缓解但易复发，甚至数十年迁延不愈。血热型银屑病主要表现为皮损颜色鲜，新出皮损不断增多，扩大。银屑病其病灶外露，病位表浅，患者常有身心困扰，从而导致患者工作、生活质量的降低。中医外治法历史悠久，有独特的优势和经验，可透达毛窍，调和经络，直达病所，发挥直接作用，从外达内，标本兼故，从而达到明显的治疗效果。

Research progress of traditional Chinese medicine external treatment for psoriasis of blood heat type

Traditional Chinese medicine believes that the main causes of psoriasis are blood loss, wind blood dryness, wind-heat pathogen, and malnutrition of skin. Many physicians use the theory of traditional Chinese medicine to classify psoriasis, which is divided into blood deficiency type, blood stasis type and blood heat type. Psoriasis of blood heat type is equivalent to the progression of the disease, an important stage in the course of psoriasis. Improper treatment and drug abuse may lead to physical unbalance, and the condition may be temporarily relieved but easy to relapse, and may last for decades. Blood-heat type psoriasis is mainly manifested as skin lesions with bright color, and increasing and expanding of new skin lesions. With lesions exposed outside, patients often have physical and mental problems, resulting in reduction of work and life quality. External treatment of traditional Chinese medicine with a long history has unique advantages and experience, and it can penetrate skin pores, regulate channels and collaterals, and treat lesions directly. From the outside to the inside, treating both manifestation and root causes, this treatment can achieve obvious therapeutic effect.
