What is resveratrol:
Resveratrol (trans-3,5,4'-trihydroxystilbene), belongs to a class of polyphenolic compounds called stilbenes , found largely in the skins of red grapes and root of Polygonum cuspidatum Sieb. et Zucc ( Japanese knotweed), is a component of Ko-jo-kon, an oriental medicine used to treat diseases of the blood vessels, heart and live.. Resveratrol is a fat-soluble compound that occurs in a trans and a cis configuration. Both cis- and trans-resveratrol also occur as glucosides (bound to a glucose molecule). Resveratrol-3-O-beta-glucoside is also called piceid.
Drug Interactions Anticoagulant and Antiplatelet Drugs
Resveratrol has been found to inhibit human platelet aggregation in vitro (42, 84). Theoretically, high intakes of resveratrol (e.g., from supplements) could increase the risk of bleeding when taken with anticoagulant drugs, such as warfarin (Coumadin), and antiplatelet drugs, such as clopidogrel (Plavix), dipyridamole (Persantine), non-steroidal anti-inflamatory drugs (NSAIDs), aspirin and others.
