[10] However, separate studies have shown that this is due to the species differences in how coumarin is metabolized within the body. Therefore "species differences in coumarin hepatotoxicity appear to be metabolism-mediated" and that "liver toxicity in patients receiving relatively high daily doses of coumarin is very rare".
