Many drugs pushed out by Big Pharma are equivalent to rat poison, but only a handful can actually claim to be rat poison. Meet warfarin: a widely used blood thinner which, prior to being used to treat a common heart rhythm disorder called atrial fibrillation, was used as rat poison.

Atrial fibrillation is an abnormal heartbeat that affects 2.2 million Americans. It occurs when the upper chambers of the heart do not dance to the beat of the lower chambers. This irregular and sometimes rapid heartbeat can cause poor blood flow, thereby increasing the risk of stroke.

Warfarin is derived from a coumarin anticoagulant (blood-clotting) chemical present in sweet clover and other plants. In the early 1920s, veterinarians noted that cows were experiencing bleeding problems during certain times of the year. This was eventually linked to the sweet clover hay that the cows were consuming, earning the name “sweet clover disease.” FULL REPORT
