Caution
What is happening. Both polyphenols have antiplatelet activity, so combining them may additively reduce platelet aggregation and increase bleeding tendency.
Mechanism. Curcumin and resveratrol each inhibit platelet aggregation, in part through modulation of the arachidonic acid and thromboxane A2 pathway, so their combined antiplatelet effects can be additive.
Recommendation. Generally safe together at supplemental doses, but use caution if you take anticoagulant or antiplatelet drugs, and stop both about 1 to 2 weeks before surgery.
