Abstract： Herpes zoster is an acute herpetic viral skin disease， with great effects on the health and quality of life of patients. According to the characteristics of skin lesions and the pathogenesis，Prof. YANG Suqing believes that the fire，heat，dampness，toxin and stasis are the major pathogenic factors and takes them as the entry point for staged treatment. Prof. YANG Suqing suggests that the disease at the initial stage is caused by the frenetic stirring of fire and heat and the overflow of fire and heat on skin，and fireheat syndrome is mostly seen， which is treated with Longdan Xiegan Decoction to clear heat and purge fire ； the disease at the middle stage is caused by the internal generation of damp-turbidity and the overflow of damp- turbidity on skin， and dampness toxin syndrome commonly occurs， which is treated with Weiling Decoction to induce diuresis and resolve dampness； the disease at the late stage is due to toxin and stasis going through the body and even overflowing the skin，and toxin stasis syndrome is mainly caused， which is treated with Taohong Siwu Decoction to detoxify and dissipate stasis. At each stage， modified prescriptions are given dynamically based on the symptoms. Prof. YANG holds that pain is the key for treatment. In clinical，common couplet medicinals for analgesia，including Cyperi Rhizoma，Corydalis Rhizoma，Persicae Semen and Carthami Flos，are used to move qi and invigorate blood；triple medicinals for analgesia in the categories of rattan medicines and worm medicines， including Lonice Raejaponicae caulis， Spatholobi Caulis， Caulis Polygoni Multiflori， Scorpio， Scolopendra and Pheretima， are flexibly applied to invigorate blood， free the collateral vessels and relieve pain， and the treatment for pain goes through the whole course. With a priority for calming the mind and lifting the spirit，Prof. YANG prefers to use Bupleuri Radix and Aurantii Fructus to sooth the liver and regulate qi；he does well in applying Campsis Flos， Rosae Rugosae Flos and other flower medicines to move qi and relieve pain； he usually adopts Margaritiferae Concha and Magnetitum for sedation and calming mind. In clinical， external treatments including fire needling and external application of Chinese medicine，are commonly combined to achieve a better therapeutic effect by adopting interior and exterior treatment simultaneously.
