Does Ginkgo help mood? (Grade C evidence)
Ginkgo may modestly help mood in specific populations (Grade C, low certainty), especially in adults with anxiety symptoms. Dose range: not standardized.
Bottom line. Ginkgo may modestly help mood in specific populations (Grade C, low certainty), especially in adults with anxiety symptoms. Dose range: not standardized. [1 RCT]
- Direction
- benefit
- Magnitude
- Systematic review and network meta-analysis of herbal anxiolytics: Ginkgo biloba showed a modest anxiety-reducing signal among the herbs assessed, but the evidence base is heterogeneous and of limited certainty.

⚠ Safety in context
- seriouswith Warfarin: Ginkgo has antiplatelet activity; with warfarin it may increase bleeding risk. full interaction →
- moderatewith SSRI: Possible additive bleeding/serotonergic effects with SSRIs. full interaction →
Grade C / low: hints of benefit in small trials; a well-run RCT could easily push this to B or to null.
Who it works for
Best-studied in adults with anxiety symptoms. Effective doses cluster around not standardized.

Why this grade
Reasoning trace
Grade C at low certainty. The grade reflects the direction and size of the effect across the 1 publishable source above; certainty reflects heterogeneity, sample sizes, and design quality. What would move it upward: additional well-powered RCTs in the target population that replicate the effect at similar doses. What would move it down: a large null trial, discovery of publication bias, or a retraction of a keystone study.

Frequently asked
How long does Ginkgo take to work for mood?
Trials of Ginkgo for mood typically report effects within 2–4 weeks, though individual response varies. Studies rarely find benefit inside 1 week for chronic outcomes.
What dose was used in studies of Ginkgo for mood?
Studied doses for Ginkgo in mood trials cluster around not standardized. See the dose block for the specific range and how it varies by form.
Does Ginkgo work for mood if I'm not deficient?
