桂枝痲黃各半湯及消風散治療皮膚搔癢症經驗

Treatment of Gui Zhi Ma Huang Ge Ban Tang and Xiaofeng Powder on Pruritus

搔癢是皮膚病常見的自覺症狀，是最難解決的問題。除了蟲癢、食癢等之外，一般可分為虛實兩種：虛者為血虛不能濡澤肌膚而癢；實者為風熱、風寒、濕熱客蘊肌膚不能疏泄而癢。血虛兼挾外邪，亦為癢。而一般治法可分為兩種：一是養血潤膚止癢法；另一是祛風除濕止癢法。本文均討論祛風除濕止癢法，首先提出風寒引起癢症之臨床醫案，以經方桂枝麻黃各半湯《傷寒論》，採用科學中藥濃縮粉劑，達到祛風寒止癢之功效而治癒。本文並提出風濕淫表，濕熱相搏型的消風散證之臨床醫案，採用消風散《醫宗金鑑》科學中藥濃縮粉劑，達到祛風濕熱止癢之功效而治癒。最後綜合對此二證型加以比較分析。

The pruritus is a kind of skin disorders with skin itching caused by primary lesions. It is difficult to treat. Except dew itch and food allergy itch, the pruritus can be classified into deficiency type and excess type. The deficiency itch is caused by blood deficiency and lack of nutrition on skin. Accumulation of damp-heat, wind-heat and wind-cold leads to the excess-type itch. Blood deficiency with outside pathogens also can cause itching. The treatment of traditional Chinese medicine includes enriching the blood and moisturizing the skin, nourishing yin, dispelling wind and arresting itching. This study aimed to discuss the application of wind-dampness-eliminating method to arrest itching. With taking the powder-type concentrated herbal extracts of Gui Zhi Ma Huang Ge Ban Tang (Treatise on Febrile Diseases), the clinical case with itching caused wind-cold was cured of his itching by wind-cold-eliminating. This study also introduced a clinical case with mixed dampness-heat syndrome. With the concentrated extracts of Xiaofeng Powder (Golden Mirror of Medicine), this patient was cured by wind-dampness-heat-eliminating. The analysis of and comparison between these two types pruritus were made in this study.
