2 interactions related to dark chocolate
cocoa + warfarin
Cocoa flavanols inhibit platelet adhesion and aggregation and can mildly prolong bleeding time. Layered on top of warfarin's anticoagulant effect, large or fluctuating intakes of cocoa can increase bleeding risk without necessarily moving the INR.

dark chocolate + blood pressure medications
Dark chocolate flavanols improve nitric-oxide-dependent vasodilation and modestly lower systolic and diastolic blood pressure (typically 2–3 mmHg). Combined with antihypertensives, this can additively lower blood pressure, occasionally producing symptoms of hypotension such as dizziness in sensitive patients.
