Prescription drugs like Lipitor, Crestor, and Zocor have become very familiar names in American homes.  Statins are among the most commonly prescribed medications for lowering cholesterol, especially in the US.  It is estimated that they are responsible for saving thousands of people each year, affected by heart disease.  These drugs work by blocking a substance your liver needs to make cholesterol, the waxy substance that’s found in fat in your blood. This causes your liver to remove cholesterol from your blood.
