Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Ginkgo biloba has been traditionally used in Chinese medicine for various circulatory disorders, but its use for supporting or treating poor circulation also has some scientific backing. Ginkgo extract is rich in flavonoids and terpenoids, which are thought to improve blood flow by dilating blood vessels and reducing blood viscosity. Several clinical studies have explored its efficacy, particularly in peripheral arterial disease (PAD) and intermittent claudication, conditions characterized by poor circulation. Meta-analyses have reported modest improvements in pain-free walking distance among patients taking ginkgo versus placebo, though results across studies are mixed and sometimes limited by small sample sizes or methodological concerns.

Ginkgo’s mechanisms are proposed to include inhibiting platelet-activating factor (PAF), improving endothelial function, and serving as an antioxidant that protects vascular integrity. While some guidelines mention ginkgo as a possible adjunct in managing symptoms of PAD, it is generally not considered a first-line treatment due to modest effect sizes and the availability of more effective therapies (such as exercise and pharmacologic agents). Furthermore, safety concerns—particularly related to bleeding risk—necessitate caution, especially in individuals taking anticoagulant or antiplatelet medications.

In summary, the use of ginkgo biloba for poor circulation is supported by both tradition and a moderate level of scientific evidence, but its clinical benefits are likely to be modest. It may be considered for those seeking complementary approaches, provided its risks and benefits are carefully weighed.
