Know your medications: Red yeast rice extract- good or bad for the heart?
Red yeast extract also know as Xuezhikang or XZK for short, has been the subject of great controversy. Is it or is not good for cardiovascular health?
On August 9, 2007, the US FDA issued a warning to consumers against the use of red yeast rice products in the treatment of high blood cholesterol. These products which are sold as nutritional supplements (and therefore bought over-the-counter (OTC)) contain lovastatin, the active ingredient of anti-cholesterol prescription drugs such as Mevacor.
