Exfoliative Dermatitis is a name of a group of symptoms which is characterized by red rash, itching and scale in almost whole body. The patients are suffered from hypoalbuminemia, general weakness and fever sign in addition to characteristic skin lesions. So in the treatment of this disease, adequate symptomatic treatment is important with adequate topical skin management. We experienced a 69 year old Korean male patient diagnosed as Exfoliative Dermatitis based on clinical symptoms and a medical certificate. We concluded that the symptoms of this patient are Sun-symptoms(癬症) and gave him Bangpungtongsung-san(剝脫性皮膚炎) and Geunsun-bang(乾癬方). After taking Oriental Medicine(the hebal medicine of internal use), clinical improvement was noticed. Based on this experience, internal use of Oriental Medicine have a good effect in Exfoliative Dermatitis.
