Abstract
A review. The phytoantitoxin resveratrol is a plant-derived polyphenol with phytoestrogenic properties. Resveratrol protects the cardiovascular system by mechanisms that include defense against ischemic-reperfusion injury, promotion of vasorelaxation, protection and maintenance of intact endothelium, anti-atherosclerotic properties, inhibition of low-d. lipoprotein oxidn., suppression of platelet aggregation, and estrogen-like actions.
Keeps lipids flowing smoothly through the blood system and helps prevent them from sticking the the artery walls.

Abstract:
A number of lines of evidence suggest that red wine may be more effective than other alcoholic beverages in decreasing the risk of coronary heart disease (CHD) mortality. This protection over and above that due to ethanol itself may be explained by phenolic components with which red wines are richly endowed. We have studied the effects of the trihydroxy stilbenetrans -resveratrol on human platelet aggregation and on the synthesis of three eicosanoids from arachidonate by platelets, i.e. thromboxane B2 (TxB2), hydroxyheptadecatrienoate (HHT) and 12-hydroxyeicosatetraenoate (12-HETE). These effects were compared with the actions of other wine phenolics (quercetin, catechin and epicatechin) and antioxidants (a-tocopherol, hydroquinone and butylated hydroxytoluene). trans-Resveratrol and quercetin demonstrated a dose-dependent inhibition of both thrombin-induced and ADP-induced platelet aggregation, whereas ethanol inhibited only thrombin-induced aggregation. The other compounds tested were inactive. trans-Resveratrol also inhibited the synthesis of TxB2, HHT, and to a lesser extent 12-HETE, from arachidonate in a dose-dependent manner. Quercetin inhibited only 12-HETE synthesis, and hydroquinone caused slight inhibition of TxB2 synthesis, the remaining compounds ...
