In the 1940s chemists discovered that ibarbascoi, a wild yam indigenous to Mexico, could be used to mass-produce synthetic steroid hormones. Barbasco spurred the development of new drugs, including cortisone and the first viable oral contraceptives, and positioned Mexico as a major player in the global pharmaceutical industry. Yet few people today are aware of Mexico's role in achieving these advances in modern medicine. In iJungle Laboratoriesi, Gabriela Soto Laveaga reconstructs the story of how rural yam pickers, international pharmaceutical companies, and the Mexican state collaborated and collided over the barbasco. By so doing, she sheds important light on a crucial period in Mexican history and challenges us to reconsider who can produce science.ppSoto Laveaga traces the political, economic, and scientific development of the global barbasco industry from its emergence in the 1940s, through its appropriation by a populist Mexican state in 1970, to its obsolescence in the mid-1990
