Professor ZHANG Binghou′s experience in the treatment of herpes zoster and sequelae neuralgia is summarized. Herpes zoster is mostly caused by the pathogenic wind and fire in the liver and gallbladder meridians

and the heat-toxicity is depressed on the skin; internal retention of damp-heat

intermingled toxicity and heat

and steamed skin cause redness and swelling; pathogenic toxin blocks the meridians and the ascending and descending of Qi is abnormal. The internal blockade of static blood causes severe pain. The herpes zoster is divided into three stages: pre-rash

eruptive

and post-herpetic neuralgia. In the pre-rash stage

the Xijiao Dihuang Decoction（犀角地黄汤） is used to clear heat and cool blood. In the eruptive stage

the Wupi Wuteng Drink（五皮五藤饮） is used to promote diuresis and dredge channels. The empirical prescription "Tengtong Sanliangsan"（疼痛三两三） is used in post-herpetic neuralgia stage to promotes blood circulation and relieves pain

according to different periods

different parts

excess of pathogenic qi

and the nature of pain.
