About

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.
