Migrant Pharmacopoeias: An Ethnobotanical Survey of Four Caribbean Communities in Amazonia (French Guiana)

Abstract

French Guiana is an overseas French department in South America at the margin of the Amazon basin. Its population is characterized by an important number of cultural groups. Many inhabitants originate from the Caribbean (mostly Saint Lucia, Martinique, Guadeloupe, Haiti, and the Dominican Republic). The objectives of this study were to present an overview of the main uses of plants among the Caribbean populations in French Guiana, and how they contribute to the dynamics of plant–based practices, in order to provide insights into ethnobotanical convergences, divergences, and hybridizations (such as the importation of new species and associated practices, and the adoption of Amazonian species by Caribbean people). Interviews and botanical voucher collections were conducted throughout the coastal area of French Guiana. Sixteen Saint Lucian, nineteen Haitian, eighteen French Caribbean, and twelve Dominican informants were interviewed during the fieldwork. Altogether they use 212 botanical species. Some plants have recently been imported directly from the Caribbean, while adaptations have also taken place: some species that do not exist locally are abandoned while Amazonian species are integrated to form hybrid pharmacopoeias. The phytotherapies of these communities in French Guiana are still conserved as consistent sets of knowledge, although they tend to blend through an ongoing process of hybridization.
