You're welcome. I wish there was a blood test like INR that worked with natural thinners, but i don't know of any. So, people like you and my wife are stuck with either taking warfarin (or more dangerous drugs) or go with natural thinners which may pose other risks.
A well informed holistic nutritionist may be able to give a better advice, but we tried a nutritionist who incidentally had a small child with heart palpitation issues and she told us that abnormal heart valve cannot be cured with nutrition alone.
