Ginkgo biloba is used for cognitive and circulation-related complaints. Side effects can include stomach upset, headache, dizziness, palpitations, or skin reactions.\n\nThe key institutional safety concern is bleeding risk—especially when combined with antiplatelet/anticoagulant drugs (e.g., aspirin, warfarin, clopidogrel). Many clinicians recommend stopping ginkgo before surgery or dental procedures.\n\nUse caution with seizure history, and avoid stacking multiple botanicals that may increase bleeding risk.\n\nBottom line: ginkgo is not benign; medication users and surgical candidates should consult clinicians before use.
