Safety & Contraindications
Not covered. Commission E reports no contraindications, adverse effects, or interactions, except for headache. Coumarins in moldy hay cause uncontrolled bleeding in cattle. High doses can cause headache, stupor, and elevated liver enzymes. Nephrotoxic in rats. Carcinogenic. Low doses of coumarin, like aspirin, reduce chemically induced endothelioma, rendering them useful in ischemic heart disease. “Coumarin has been used to treat brucellosis in humans, and other chronic infections, including mononucleosis, mycoplasmosis, toxoplasmosis, Q fever, and psittacosis”. Dicoumarol is >1000 times better than coumarin as an antiaggregant. Grapefruit juice slows body conversion of coumarin to umbelliferone..
