A large clinical trial testing the effects of aspirin and Plavix to prevent small strokes was stopped because there was no added benefit by combining these drugs and the risk of bleeding was too high. This information was presented at the 2012 American Stroke Association meeting in February of 2012. A second abstract presented at the same conference showed that Coumadin and aspirin were equally effective in preventing deaths and strokes in patients with congestive heart failure.
All of the drugs used to anticoagulate people in mainstream medicine, which includes, aspirin, Plavix, Coumadin, and Pradaxa are associated with potentially life-threatening bleeding. Coumadin also has the effect of causing osteoporosis and accelerating arteriosclerosis after just 2 years of treatment. Nutritional medicine offers several options that include fish oil, nattokinase, lumbrokinase, and ginkgo biloba, but they have been alll but ignored by MDs because there's not sufficient research to compare the effects of mainstream drugs to these nutrients. These studies should be done the by NIH!
