Rating (out of 5): 2

Ginkgo biloba has been investigated for its potential benefits in stroke recovery, primarily due to its antioxidant, anti-inflammatory, and neuroprotective properties. Several clinical trials and meta-analyses have examined ginkgo's efficacy in improving cognitive and neurological outcomes after ischemic stroke. The most commonly studied preparation is EGb 761, a standardized extract of Ginkgo biloba leaves. Some studies have reported modest improvements in cognitive function, activities of daily living, and neurological deficits when ginkgo is used as an adjunct to conventional stroke therapy. For example, a 2018 randomized controlled trial published in Stroke & Vascular Neurology found that EGb 761 improved cognitive and neurological outcomes in patients with acute ischemic stroke over a 6-month period compared to standard therapy alone.

However, the overall quality of evidence is low to moderate, with concerns regarding small sample sizes, variability in study design, and potential publication bias. Systematic reviews and meta-analyses suggest that while there may be some benefit, the magnitude of effect is unclear and not universally accepted by the medical community. Major guidelines do not currently recommend ginkgo as a standard treatment for stroke recovery. Additionally, ginkgo may increase bleeding risk, especially when combined with anticoagulant or antiplatelet medications, which are commonly prescribed post-stroke.

In summary, there is some scientific evidence supporting the use of Ginkgo biloba as an adjunctive therapy in stroke recovery, but the evidence is limited and not robust. Consultation with a healthcare professional is essential before use.
