I agree with you on the garlic for people that don't have bleeding issues. As for the cayenne, I find it too irritating, although others may tolerate it better. It seems that there is conflicting information on the net about cayenne and its effects on clotting. Perhaps its action might be different for exposed wounds open to the air, and clotting within the body? I am trying to reconcile the different information I have read and make sense of it. My personal experience is that garlic,clove oil, and ginger are much easier to tolerate than cayenne.
