Aspirin Low-Dose and Ginger Extract, a caution.
Ginger extracts contain gingerols and shogaols that inhibit cyclooxygenase and thromboxane A2 synthesis, reducing platelet aggregation. Added to aspirin's irreversible COX-1 inhibition, ginger supplements stack antiplatelet activity and can raise bleeding risk, particularly perioperatively.

Caution
What is happening. Ginger extracts contain gingerols and shogaols that inhibit cyclooxygenase and thromboxane A2 synthesis, reducing platelet aggregation. Added to aspirin's irreversible COX-1 inhibition, ginger supplements stack antiplatelet activity and can raise bleeding risk, particularly perioperatively.
Mechanism. Gingerols and shogaols inhibit COX activity and reduce platelet thromboxane A2 generation. This overlaps with and adds to aspirin's irreversible COX-1 inhibition of platelet function.
Recommendation. Avoid concentrated ginger extract on aspirin. Culinary amounts of ginger in food are fine. Stop ginger supplements at least 7 days before any planned surgery.
