Stevia rebaudiana bertoni is a member of the Compositae family. The Stevia plant is native of eastern Paraguay. Our Stevia is a newly developed hybred from Canada called Balckbird and is a little bit sweeter than anything else in the world but the big difference is that it no longer has a "bitter" taste. This is a cleaner sweetness. This new Stevia is grown "Certified Organic". http://www.shilajeet.com/store/Stevia-Leaf-Cut-Certified-Organic-3-0-42.html en Sat, 23 Jul 2005 13:11:22 EDT
