Synopsis

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

Ginkgo biloba has been traditionally used in Chinese medicine for various circulatory disorders, including those related to the brain. In recent decades, scientific interest has focused on Ginkgo's potential neuroprotective and vascular effects, specifically for stroke patients. Some laboratory and animal studies suggest that Ginkgo extracts may reduce oxidative stress, improve blood flow, and inhibit platelet aggregation, all of which could theoretically benefit stroke patients by protecting brain tissue and reducing secondary injury. However, evidence from human clinical trials is limited and mixed. A few small trials and meta-analyses have explored Ginkgo's effects in acute ischemic stroke or in stroke recovery, often as an adjunct to standard care. Some studies have reported modest improvements in cognitive or neurological outcomes, while others found no significant benefit. Major methodological limitations—such as small sample sizes, short durations, and inconsistent endpoints—make it difficult to draw firm conclusions. Additionally, concerns about increased bleeding risk, especially when combined with anticoagulant medications, further complicate its use in this population. Overall, while there is a scientific rationale and some preliminary evidence for Ginkgo’s use in stroke patients, the quality and quantity of clinical evidence is low. Major stroke treatment guidelines do not currently recommend Ginkgo for stroke prevention or recovery.
