How will these herbs affect my Coumadin and INR?

What are the effects of the following herbs on my Coumadin and my INR (warfarin): burdock root, echinacea, and gotu kola?

The Health meets Food Team Says...

No one knows for sure what the effects of these herbs would be on INR for folks who take Coumadin (warfarin). There's no health benefit for anyone that's been proven for any of these, so there's no reason to take them and no reason to take the risk.

Thanks for writing
