Use Patterns of Medicinal Plants by Local Populations

In this chapter, the similarities and differences in the ways by which local populations appropriate available plant resources are discussed. Patterns related to taxonomy, plant habit, biogeographical origin, and therapeutic indications are discussed to illustrate how the environment may play an important role in the composition of local pharmacopoeias. We show that some plant families are overused for medicinal purposes in a wide variety of contexts (e.g., Asteraceae) while some others are commonly underused in several studies (e.g., Poaceae). We also challenge the idea that herbs are the main components of traditional pharmacopoeias and the idea that the entrance of exotic species in local medical systems is necessarily related to a process of acculturation. The reasons why the most important body systems (in terms of number of medicinal plants) are commonly the same are also discussed. Many of the topics addressed here could be applied to other areas of study, including ethnozoological research because little is known of the behavioral patterns related to animal use.
