Atopic dermatitis (AD), also known as atopic eczema, is a chronic inflammatory skin disorder. The current first-line recommended treatment for AD is the use of emollients, topical corticosteroids (TCS), and oral antihistamines if necessary. However, patients often have side effects like skin atrophy and telangiectasia. And there were plenty of herbal medicine which are beneficial to atopic dermatitis in ancient Chinese medicine books and records. Therefore, the purpose of this study is to develop a new topical application of traditional Chinese medicine and evaluate its clinical efficacy in AD patients. In human trial, 66 Subjects diagnosed as AD will be enrolled and treated with Sophora flavescens Aiton topical ointment. After treatment we will estimate the efficacy and record adverse events to conduct statistically analysis.

The 1st year project: (1) Expect to enroll 66 clinical subjects of AD. (2) Evaluate subjects 'symptom and proceed herbal ointment treatment. (3) Record treatment responses including adverse effect. (4) Conduct statistically analysis.

The 2nd year project: (1) Completing enrollment of 66 clinical subjects of AD. (2) Finish evaluation and treatment of all subjects. (3) Statistically analysis all collecting data (4) Discuss and analyze the outcome.
