Hello all ~ As far as I know I am the only one who has compiled a list of herbs that should not be used with blood-thinners. See below: Many people out there who have heart problems or stroke find themselves on blood thinners (Warfarin) mainly marketed as coumadin. Coumadin reacts with certain herbs and so should not be taken with them. They can either raise or lower clotting times depending upon their constituents. It is important to know which herbs do this. My criteria in making the list was 2 fold: a) if a constituent was listed as a coumarin family member b) if there was a warning that the herb would either raise or lower PT (prothrombin or clotting times) Partial list of coumarins contained in herbs: aesculin aesculetin allo-xanthoxyletin cichoriin coumarin caffic and hydrocinnamic acids fraxin medicagol scopoletin xanthyletin xanthoxyletin furocoumarins include: bergapten methoxypsoralen psoralen oxypeucedanin Herbs which contain salicylic acid which may potentiate blood thinners: Meadowsweet Ladies Mantle Senega White Willow Bark Other herbs which had alerts in use with anti-coagulants: Balsam of Peru Poplar Capsicum Tumeric Irish Moss Lungwort Heparin (potent blood thinner) family - Chrondroitin List of Herbs from the Coumarin family: Angelica Black Haw Bogbean Buchu Butchers Broom Chamomile Chickweed Cinnamon Condurango Coriander Dill Dong Quai Fenugreek Horse Chestnut Horseradish Jimsonweed Lavender Lovage Mugwort Passion flower Prickly Ash Queen Anne's Lace Red Clover Rue Sea Holly Tonka Bean Tumeric Wild Lettuce This list is not complete, but was taken from: Complementary & Alternative Medicines by Charles Fetrow and Juan Avila. If you are considering using these herbs it is best to research their activity first. In health - Mary Mary L.
