What the Science Says

Ginkgo biloba is a tree extract used for centuries in traditional medicine. Clinical trials show it can meaningfully reduce dizziness and vertigo symptoms, improve memory and cognitive scores in healthy adults, and help children with nighttime bedwetting — especially when combined with standard treatments. At 240 mg daily, about two-thirds of vertigo patients showed clinically relevant improvement within 12 weeks.

What It Doesn't Do

Not a proven treatment for dementia or Alzheimer's disease based on these studies. Won't cure hearing loss on its own — the hearing study combined it with another drug. No solid evidence it boosts spatial awareness or multitasking in gamers. Don't expect it to work overnight — most benefits appeared after weeks of consistent use.

Red Flags to Watch For

  • The vertigo trial was open-label with no placebo control, making it impossible to separate drug effects from natural recovery
  • Ginkgo biloba can interact with blood thinners (e.g., warfarin) and other medications — the asthma drug interaction review flags herb-drug interactions as a real concern
  • The children's bedwetting trial used a specific standardized extract (GBE 60 mg) — generic ginkgo products may not match study formulations
  • Some studies used proprietary extracts (EGb 761) that may differ significantly from over-the-counter supplements
  • The esports/gaming study showed no advantage over placebo for spatial localization or multitasking — common marketing claims for focus supplements
