摘要

乾癬(Psoriasis)古稱白疕，也是中國大陸所說的銀屑病，是一種常見的易於復發的炎症性皮膚病。其特點是在紅斑上有鬆散的銀白色鱗屑，抓之有薄膜及露水珠樣出血點。在中醫古文獻中有“乾癬”、“疕風”、“銀錢瘋”、“白殼瘡”、“蛇虱”等名稱，其名各異，症狀也有所差異，但都是從不同角度較爲形象的描述了本病的特徵。據有關文獻統計[1]，日本銀屑病的發病率小於0.1%，美國爲2.6%，丹麥法羅群島的自然人群發病率高達3%，據國外流行病學調查結果顯示，銀屑病的發病率爲0.1%-3%。一般來說，銀屑病的發病率白種人高於黃種人，黑種人次之。中國大陸於1984年流行病學調查，銀屑病發病率爲0.167%，台灣雖並無正式盛行率的報告，但健保資料庫中，每年乾癬就診人數約爲8萬人，男女的發生率是相等的。在任何年齡都可能出現乾癬，在臺大的統計男性平均出現於35.5歲，而女性爲30.4歲。中醫治療銀屑病有上千年的歷史，積累了豐富的經驗。

並列摘要

Psoriasis was called ”white scab” in the literature and is called ”silver peel disease” in China. It is a common inflammatory skin disease that relapses easily. The characteristics are the silver white skin peel, thin film and dew-like bleeding when scratching. There are different names in the Chinese literature describing different symptoms of this disease, such as ”dry scab”, ”scab wind”, ”silver coin wind”, ”white shell scab” and ”snake scab” etc.. According to literature statistics, the morbidity of psoriasis in Japan is less then 0.1%, 2.6% in the States, and 3% in Denmark. According to the epidemiology research, the morbidity of psoriasis is 0.1% to 3%. Generally speaking, the morbidity of psoriasis is higher in Caucasians than Asians and Black. The epidemiology research done in China in 1984 shows the morbidity of 0.167%. In Taiwan, there is no report on the epidemiology of psoriasis, but the databank in the Health Care shows 80,000 people sought treatment options every year with equal proportion between male and female. Psoriasis can happen at any age. The average onset of male patient is 35.5 years old, while that of female patient is 30.4 years old. The treatment of psoriasis has been in the TCM history for thousands of years with abundant clinical experience.
