Ginkgo biloba

EMA Well-Established Use extract (EGb 761) for age-related cognitive complaints; Cochrane evidence is mixed but the regulatory tier is high.

Why

Ginkgo biloba leaf extract (EGb 761) holds an EMA Well-Established Use monograph for symptomatic treatment of mild dementia, and a Traditional Use registration for age-related cognitive complaints. The Cochrane review of ginkgo for cognitive impairment and dementia found inconsistent results across older trials but a positive signal at 240 mg/day in larger, more recent RCTs. A separate Cochrane review supports symptomatic benefit in intermittent claudication.

How it works

Flavonoid glycosides (ginkgolides A, B, C) inhibit platelet-activating factor and improve microvascular perfusion. Terpenoid lactones scavenge reactive oxygen species and protect neuronal mitochondria.

Expected onset · Cognitive endpoints typically assessed over 12–24 weeks; claudication walking-distance effects emerge by 8–12 weeks

How to take

Dosage

EGb 761 standardised extract 120–240 mg/day, in one or two divided doses.

Timing

Morning, or split morning + evening

On the label

Look for 'EGb 761' or extracts standardised to 24% flavone glycosides and 6% terpene lactones. Unstandardised leaf preparations are poorly characterised.

Ideal for

Older adults with subjective memory complaints or early-stage cognitive symptoms; adults with mild intermittent claudication.

Safety

Anti-platelet effect; stop at least 2 weeks before surgery. Caution with warfarin, DOACs, antiplatelets, SSRIs, and NSAIDs. Avoid in pregnancy. Seizure threshold concerns at very high doses; avoid in epilepsy.

Evidence

At a glance

EMA HMPC classifies dry quantified leaf extract as Well-Established Use for symptomatic treatment of mild dementia: the highest regulatory tier for a botanical. Cochrane 2009 SR found inconsistent results overall, with the stronger signal in larger trials at 240 mg/day of EGb 761. Cochrane 2013 SR on claudication found a small but statistically significant improvement in pain-free walking distance vs placebo.
