Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Ligusticum (notably Ligusticum chuanxiong, also known as Szechuan lovage or Chuanxiong) has a long history of use in traditional Chinese medicine (TCM) to support circulation, particularly to the brain. In TCM, Chuanxiong is commonly prescribed for conditions such as headaches, dizziness, and stroke recovery, all of which are often attributed to impaired blood flow or "blood stasis." The herb is believed to "invigorate the blood," promote the movement of qi, and dispel wind, making it a staple in formulas addressing cerebrovascular concerns.

Scientific evidence supporting these uses is still limited. Some preclinical studies and animal models suggest that extracts of Ligusticum chuanxiong (especially its active compound ligustilide) may have vasodilatory, antiplatelet, and neuroprotective effects, which could theoretically improve cerebral circulation. However, robust clinical trials in humans are lacking, and most evidence comes from laboratory or traditional use rather than rigorous modern research.

Therefore, while Ligusticum is widely used in traditional medicine for promoting circulation to the brain, this use is not yet strongly validated by contemporary scientific research. The evidence rating is moderate based on traditional use, but low from a scientific standpoint.
