⚠ 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. Recorded studied dose: not standardized.
