For over a century, plant specialists worldwide have sought to transform healing plants from African countries into pharmaceuticals. And for equally as long, conflicts over these medicinal plants have endured. In Bitter Roots, Abena Dove Osseo-Asare draws on publicly available records and extensive interviews with scientists and healers in Ghana, Madagascar, and South Africa to interpret how African scientists and healers, rural communities, and drug companies - including Pfizer, Bristol-Myers Squibb, and Unilever - have sought since the 1880s to develop drugs from Africa's medicinal plants. Osseo-Asare recalls the efforts to transform six plants into pharmaceuticals: rosy periwinkle, Asiatic pennywort, grains of paradise, Strophanthus, Cryptolepis, and Hoodia. Through the stories of each plant, she shows that herbal medicine and pharmaceutical chemistry have simultaneous and overlapping histories that cross geographic boundaries. At the same time, Osseo-Asare sheds new light on how various interests have tried to manage the rights to these healing plants and probes the challenges associated with assigning ownership to plants and their biochemical components. A fascinating examination of the history of medicine in colonial and post-colonial Africa, Bitter Roots will be indispensable for scholars of Africa; historians interested in medicine, biochemistry, and society; and policy makers concerned with drug access and patent rights.

After Atomic Junction, along the Haatso-Atomic Road there lies the Ghana Atomic Energy Commission, home to Africa's first nuclear programme after independence. Travelling along this road, Abena Dove Osseo-Asare gathers together stories of conflict and compromise on an African nuclear frontier. She speaks with a generation of African scientists who became captivated with 'the atom' and studied in the Soviet Union to make nuclear physics their own. On Pluton Lane and Gamma Avenue, these scientists displaced quiet farming villages in their bid to establish a scientific metropolis, creating an epicentre for Ghana's nuclear physics community. By placing interviews with town leaders, physicists and local entrepreneurs alongside archival records, Osseo-Asare explores the impact of scientific pursuit on areas surrounding the reactor, focusing on how residents came to interpret activities on these 'Atomic Lands'. This combination of historical research, personal and ethnographic observations shows how Ghanaians now stand at a crossroad, where some push to install more reactors, whilst others merely seek pipe-borne water.
