Objective : This study was designed to analyze the herbal medicine case-control studies of tic disorder in traditional chinese medicine. Method : For this study, we searched the studies on tic disorder, which had been published 2007, through web-site CNKI(中國知識基魔設施工程) http://www.cnki.net). There were 15 herbal medicine case-control studies and we focused on those studies. Results: 1. DSM-IV(7 studies), CCMD(5 studies) and ICD-10(3 studies) were frequently used in the diagnosis of tic disorder. 2. Paeonia radix alba, Uncariae ramulus et uncus and Glycyrrhizae radix were frequently used in treatment. Moreover Scorpio, Gastrodiae rhizoma, Pinelliae rhizoma and so on were used. 3. Treatment results were assessed by improvement of symptom, YGTSS and so on. 4. Herbal medicine treatment was more effective than western medicine treatment in most studies, and side effects of herbal medicine were far less than those of western medicine. Conclusion : There have been reported many herbal medicine treatment studies of tic disorder in traditional chinese medicine. We believe that these studies can be applied to the clinical practices in Korean medicine.
