Medicinal plant knowledge in a context of cultural pluralism: A case study in Northeastern Brazil

摘要

Ethnopharmacological relevance: The study of plant use in contexts of migrations can give important insights to cultural evolution, since people face rapid changes in their environments and often start interacting with native dwellers, both constituting forces that can lead to change. Therefore, this study focused on medicinal plant knowledge and transmission in order to understand what happens to such knowledge when people from several regions converge to a single place already inhabited by native people.
