I have a blood disorder which makes me prone to blood clots for which I have to take Warfarin (a blood thinner). Unfortunately it has interactions with many other drugs which rules them out for me so I tend to try lots of the old wives remedies - some of them seem even seem to work!

I've also found the natural unpasteurised apple cider vinegar (with mother) works pretty well but it's not the most pleasant thing to drink. It can be incorporated into salad dressings though so could be a worth while little and often thing to try.
