It contains a naturally-occurring form of the statin drug lovastatin (marketed as Mevacor). So the FDA ruled that RYR was a regulable drug, and thus ordered it removed it from the shelves.This FDA decision was initially overruled by the District Court of Utah in 1999, but in 2000 the 10th U.S. Circuit Court of Appeals agreed with the FDA that RYR could be regulated. So RYR could still be sold legally in the U.S., but only if steps were taken in its manufacturing process to remove the lovastatin (presumably eliminating its effectiveness).

Then, in 2007, the FDA found that at least some RYR in the U.S. still contained lovastatin, and (after issuing a formal FDA Consumer Safety Alert) took further steps to purge the "tainted" products from the shelves.

I guess it does not contain it anymore.
