Blood Thinning Supplements
Possible Harmful Interaction
Fibrate drugs are known to increase the "blood thinning" effects of drugs in the
warfarin
(Coumadin) family. Certain herbs, such as garlic, danshen, devil’s claw, dong quai, papaya, PC-SPES and red clover, may thin the blood in a manner somewhat similar to warfarin. Although no such interactions have yet been reported, it is at least theoretically possible that combined use of these herbs and fibrate drugs could pose a risk of bleeding problems.
