The Food and Drug Administration (news - web sites) warned consumers Tuesday not to buy or use the supplements Actra-Rx or Yilishen because they contain an ingredient that could lower blood pressure to unsafe levels. The FDA (news - web sites) also instructed employees to block imports of the supplements, calling them “dangerous ... and even life-threatening.” The agency said the supplement bears the name Yilishen when it is imported from China and is sold as Actra-Rx within the United States.
