How much garlic can I use daily if I am on Coumadin (warfarin)?

I would like to know how much cooked fresh garlic per day I can use. For example, if I chop half an average size clove to season two pork chops, then pan fry them and add the marinating sauce with the garlic and simmer the chop in it for about 5 minutes. Would that cause me to bleed if I am on 5 mg of Coumadin daily?

Dr. Gourmet Says...

There's no evidence that garlic will have any effect whatsoever on blood clotting or the effectiveness of Coumadin (warfarin). Eat all you like (or your significant other can tolerate on your breath).

Thanks for writing,
