Ligustrazine (tetramethylpyrazine) is a bioactive ingredient extracted from the widely-used Chinese herb, Chuanxiong. It inhibits of platelet aggregation, enhances of vessel dilation, increases cerebral blood flow and possesses neuroprotective properties. The injection solution of ligustrazine has been used especially in China to treat ischemic stroke, coronary heart disease, diabetic nephropathy, and knee osteoarthritis. Ligustrazine was also evaluated in clinical as a remedy for pressure sores, as a salvage agent for patients with non-Hodgkin's lymphoma, as a treatment for bronchial asthma and vertebrobasilar insufficiency.

Sample Use Guides
In a clinical trial for the treatment of pressure sores, ligustrazine was applied with a transdermal patch. For treatment of bronchial asthma, ligustrazine was administered by inhalation. For treatment of vertebrobasilar insufficiency, ligustrazine was administered intravenously (80 mg of ligustrazine in 250 ml of 5% glucose or 0.9% normal saline for 15 days).
