Evidence-Based Benefits

  • Cerebral blood flow — ginkgo's terpene lactones (ginkgolides) inhibit platelet-activating factor (PAF), improving microcirculation in the brain and periphery
  • Cognitive function in elderly — a 2014 meta-analysis of 21 trials (n=2,608) found EGb 761 at 240mg/day significantly improved cognition and daily function in patients with mild cognitive impairment and dementia
  • Antioxidant neuroprotection — flavonoid glycosides scavenge free radicals and protect neuronal mitochondria from oxidative damage, reducing age-related neuronal loss
  • Tinnitus relief — several European trials show 120-240mg EGb 761 daily reduces tinnitus severity, though results are mixed across studies
  • Peripheral circulation — ginkgo improves blood flow to extremities, benefiting conditions like Raynaud's syndrome and intermittent claudication

What the Research Says

Ginkgo biloba is among the most extensively studied herbal medicines, with hundreds of clinical trials. The large GuidAge trial (n=2,854) found that while ginkgo did not prevent dementia onset in healthy elderly, it reduced risk in a compliant subgroup. A 2014 Cochrane-quality meta-analysis of EGb 761 confirmed modest but statistically significant cognitive benefits in patients with existing cognitive impairment. The GEM trial (n=3,069) in the US found no prevention benefit in healthy elderly. The European medical consensus favors ginkgo as an evidence-based treatment for mild-to-moderate dementia and cognitive decline.
