Warfarin is a drug that interferes with the body’s clotting mechanism. It takes some time to kick in, unlike heparin, and is given to prevent clotting in deep vein thrombosis or emboli.

Careful monitoring of blood clotting time is required but it may be a life-saving compound. Naturopathic treatments are available but should only be prescribed by a competent and experienced complementary medical practitioner with experience in herbal medicine.
