Caution
What is happening. Both have mild antiplatelet activity; combined chronic use can additively increase bleeding tendency, especially with concurrent NSAIDs or anticoagulants.
Mechanism. Ginkgo inhibits platelet activating factor (PAF); fish oil EPA reduces thromboxane A2 production. Additive antiplatelet effect.
Recommendation. Use together cautiously. Stop both 7 to 14 days before scheduled surgery. Monitor for easy bruising, nosebleeds, or prolonged bleeding from cuts.
