The following is from Andreas Kalcker's book, Forbidden Health.
"Many people, especially those with coronary issues, are on anticoagulants (blood thinners), which don’t really make blood any thinner; they merely decrease the ability for coagulation, preventing the formation of blood clots in the cardiovascular system. The best known is Warfarin (Coumadin®), the same substance that is widely used as a rat poison because it causes fatal hemorrhages.
As a preventative measure, keep in mind that blood thinners may interact with the treatment. Chlorine dioxide doesn’t thin blood directly; it makes the red blood cells repel each other, changing the counts."
