Objective To explore the pattern distribution and formula law of Chinese medicine for Parkinson’s disease（PD） according to literature study.Methods The articles of randomized controlled clinical studies on Chinese medicine and integrative medicine for PD were searched from VIP database

Wanfang database and China National Knowledge Infrastructure（CNKI）.The frequency and cluster analysis was applied to analyze the pattern

medicinal

efficacy and channel entry of medicinal.Results Totally 116articles were included and 14patterns were involved.The most frequent pattern was liverkidney yin deficiency pattern and it accounted for 55.2%

with a significant difference between other patterns（P<0.01）.Totally 140kinds of medicinal were involved and the overall frequency of medicinal application was 1 102.The commonly used herbs were Baishao（Radix Paeoniae Alba）

qi-supplementing medicinal

kidney-supplementing essence-securing medicinal

yang-supplementing medicinal

heatclearing blood-cooling medicinal

liver-repressing medicinal and orifice-opening medicinal

especially blood-supplementing medicinal

liver-calming wind-extinguishing medicinal and blood-quickening medicinal（P<0.01）.There were significant differences in the distribution of channel entry of 140herbs（P<0.01）

especially the proportion of liver channel（P<0.05）.Conclusion The main pattern of PD is liver-kidney yin deficiency pattern and kidney-supplementing liver-emolliating and bloodquickening stasis-transforming herbs are commonly used.
