Notes
grade-b Minor High See all 4 studies
Possible decreases in platelet aggregation
grade-c Notable Very High See all 5 studies
Both acute and prolonged ingestion of reasonable levels of cocoa flavonoids (500mg or more) appear to reduce the aggregation of platelets, although the potency is lesser than that of a baby aspirin (81mg).
grade-c Minor Very High See all 4 studies
Garlic appears to reduce platelet aggregation at the supplemental dose, but not a moderate dietary dose of garlic cloves. The potency is less than ginkgo biloba as a reference.
