Synopsis

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

Puerarin, an isoflavone derived from the root of Pueraria lobata (Kudzu), has a long history in traditional Chinese medicine (TCM), where it is used to treat headaches and related conditions, including migraines. The traditional use is based on its proposed ability to "dispel wind" and "relieve pain," concepts rooted in TCM theory rather than modern pathophysiology. Several TCM formulas containing Kudzu root have been prescribed historically for symptoms compatible with migraine, such as severe, recurring headaches.

Scientific research on puerarin’s efficacy for migraine is limited and largely preclinical. Some animal studies suggest that puerarin may have neuroprotective and vasodilatory effects, and may influence neurotransmitter levels, all of which could theoretically be beneficial in migraine. However, robust clinical trials in humans specifically evaluating puerarin for migraine prevention or treatment are lacking. The evidence, therefore, remains largely anecdotal and traditional, with only preliminary scientific exploration but no firm validation. Most of the available studies are from China and are often of low methodological quality or published in regional journals, making it difficult to draw definitive conclusions about its efficacy for migraines.

In summary, puerarin's use for migraine is primarily justified by traditional practices rather than strong scientific evidence, with a low overall level of support from modern clinical research.
