Hi folks,

As subscribers to this list are (in general) avid consumers of fruit and 
some of us may be taking anticoagulant drugs such as warfarin 
(Coumadin), I noticed these reports and wanted to share the information. 
I am aware of the potential anticoagulant enhancing effects of leafy 
greens. In fact, that effect is commonly included in patient teaching 
during the initiation of Coumadin therapy; I was not previously aware of 
any association with fruit.

A report on the effects of goji berry enhancing the anticoagulant 
properties of medication.


A report on the effects of cranberry enhancing the effect of 
anticoagulant medication.


These are not newly reported associations, but I have never heard a health care provider warn against potential interactions between fruit and warfarin. So if you are a consumer of these fruits and are a patient having problems with the effects of your oral anticoagulants, this potential interaction may be something to discuss with your health care provider.
