Research Progress of Acupuncture and Moxibustion in the Treatment of Postherpetic Neuralgia

带状疱疹后遗神经痛(Postherpetic Neuralgia, PHN)是疱疹病毒损伤神经后遗留的顽固性疼痛综合征，中医理论将其归属于“蛇串疮”、“缠腰火丹”、“火带疮”等范畴，病机关键为“不通则痛”和“不荣则痛”，核心在于“余毒未清、经络阻滞、气血阴阳失养”。本文系统梳理近10年针灸治疗PHN的研究进展，为临床实践提供参考。Postherpetic Neuralgia (PHN) is an intractable pain syndrome left by herpes virus after nerve injury. According to the theory of traditional Chinese medicine, it belongs to the categories of “snake-string sores”, “waist-winding fire pill” and “fire-belt sores”. The key pathogenesis is “pain due to obstruction” and “pain due to dishonor”, and the core lies in “unclear residual poison, meridian blockage and qi, blood, yin and yang malnutrition”. This paper systematically combs the research progress of acupuncture treatment of PHN in recent 10 years, and provides reference for clinical practice.
