About

To evaluate the efficacy and safety of using Chinese Medicine Angong Niuhuang Wan in stroke patients, the modified Rankin Scale (mRS) score will be used as primary outcome, the National Institutes of Health Stroke Scale (NIHSS) score, The Modified Barthel Index (MBI) score and the Montreal Cognitive Assessment (MoCA) scores will be used as secondary outcome measures.

Full description

This study is a randomized, double-blind, placebo-controlled trial which is used to further determine the effectiveness of Angong Niuhuang Wan in treating stroke patients on top of the standard conventional treatment, also to evaluate the improvement level on quality of life of post-stroke after using Angong Niuhuang Wan. The effect of Angong Niuhuang Wan on liver and kidney function will be focused and using NMR techniques to analysis metabolomics to further study the safety and effectiveness of Angong Niuhuang Wan on the prevention and treatment of stroke.

It is a 24-week trial, Double-blind treatment for 1 week, follow up visit for 23 weeks. All participant will have study blood taking for renal and liver function test and questionnaires assessment during study visits. Informed consent will be obtained before study enrollment.
