South African San Bushmen are negotiating to share in profits from the development of a slimming drug based on their traditional appetite supressant made from the local Hoodia gordonii plant. What a box of teeth discovered in a basement can tell us about nuclear fallout.

NOTE: In 2002, the South African Council for Scientific and Industrial Research acknowledged the San Bushmen's rights over the Hoodia gordonii plant, giving them a share in any profits. However, Pfizer released the rights to the primary ingredient in 2002. A clinical trial published in the American Journal of Clinical Nutrition in 2011 found it ineffective as a weight-loss drug.
