Ligusticum chuanxiong
Sichuan TCM herb used to move blood and qi, particularly for headache, menstrual conditions, and cardiovascular support.
Ligusticum chuanxiong (Chuanxiong) is a traditional Chinese herb used primarily to invigorate blood and move qi, with modern applications as a vasodilator, antispasmodic, and anti-inflammatory agent. Its key active compounds include ligustilide, butylidenephthalide, ferulic acid, and tetramethylpyrazine, which contribute to its cardiovascular and neurological benefits. Clinical evidence supports its use for headaches, menstrual disorders, and improving microcirculation, though most studies are limited to pilot or traditional contexts.
Ligusticum chuanxiong exerts vasodilatory effects primarily through ligustilide and tetramethylpyrazine, which inhibit voltage-gated calcium channels and activate endothelial nitric oxide synthase, leading to increased nitric oxide production and smooth muscle relaxation. Its antiplatelet and antithrombotic actions are mediated by ferulic acid and butylidenephthalide, which suppress thromboxane A2 synthesis and platelet aggregation via COX-1 and COX-2 inhibition. Additionally, the herb demonstrates anti-inflammatory activity by downregulating NF-κB and reducing pro-inflammatory cytokines such as TNF-α and IL-6.
