How to practice Ginkgo biloba
Use standardized extract (24% flavone glycosides, 6% terpene lactones) at 120–240 mg/day, divided into two doses. Effects accumulate over 4–8 weeks. Take with meals. Avoid concurrent use with anticoagulant drugs or before surgery. Best used for adults seeking long-term vascular or memory support rather than acute stimulation.
The evidence behind Ginkgo biloba
Ginkgo enhances cerebral circulation and protects neurons from oxidative damage. Dozens of RCTs show modest cognitive improvement in mild cognitive impairment and vascular dementia; evidence for healthy adults is mixed but suggestive for attention and mental clarity. Mechanistic data show improved perfusion and reduced platelet aggregation. Safe overall, though mild headaches or bruising can occur due to antiplatelet effects.
