Ethnopharmacology of Medicinal Plants in the North and West of Dashtestan County, Bushehr

Ethnopharmacology is a very diverse approach to drug discovery that involves the observation, description, and experimental study of native drugs and their biological activities based on botany, chemistry, biochemistry, pharmacology, and other disciplines such as anthropology, archeology, history, and linguistics that helps discovering of natural products with biological activity. The aim of this study was to identify medicinal plants that have a traditional use in the north and west of Dashtestan county, Bushehr in the north of Persian Gulf.
