Caution
What is happening. Combined antiplatelet activity may modestly increase bleeding tendency, particularly in those on anticoagulant or antiplatelet drugs or approaching surgery.
Mechanism. Ginger inhibits thromboxane and platelet aggregation while garlic organosulfur compounds also suppress platelet aggregation, giving a potentially additive antiplatelet effect.
Recommendation. Generally well tolerated, but monitor for bruising or bleeding and stop both 1 to 2 weeks before surgery. Use caution with blood thinners.
