In December of 2009, the FDA issued a letter stating the Rebiana and other products made from a specific part of the stevia plant and meeting purity standards of 97% or higher would be "non-objectionable" as food additives. This was a semi-reversal of the FDA's previous stance on stevia products. Until 2009, stevia products were banned as food additives in the U.S. because of research that indicated a possible cancer risk. Cargill, the agricultural giant, was able to demonstrate to the FDA that Reb-A containing products were safe and the FDA agreed.
You can find Rebiana in assorted products, most notable the sweetener Truvi which is sold as a stand alone sweetener and also found in Coco-Cola products.
