Parkinsonism is a cluster of neurodegenerative disease with motor and non-motor symptom. However, there is still a lack of research on the treatment for non-motor symptoms of Parkinsonism, especially autonomic dysfunctions such as orthostatic hypotension. Efficacy and safety of astragalus for non-motor symptoms of Parkinsonism will be assessed by an open-label self-controlled before-and-after study.
