Resveratrol and platelet aggregation:
Resveratrol has been found to exert a number of potentially beneficial cardioprotective effects, including inhibition of platelet aggregation in both men with normal blood pressure and in rabbits with high cholesterol. Platelets are the smallest blood cell produced in the bone marrow that react to injury and prevent bleeding by clot formation. Compared to normal animals, platelet aggregation increased by about 21.5% in the high-cholesterol fed group. Platelet aggregation in hypercholesterolemic rabbits was inhibited both by resveratrol at a dose of 4 mg per kilogram, and when Chinese red wine was given with or without alcohol at 4 ml/kg/day. (10)
