Traditional medical lore along with its practitioners – druggists and healers – survives in Yemen today. Owing to the country's rich biodiversity, the main body of the medicines is plant-based. This book features fourteen scholars from Europe, North America and the Middle East (three of them from Yemen) who represent both humanities and natural sciences. They address the topic of herbal medicines and their multifaceted applications within traditional Yemeni society across boundaries of disciplines, such as Islamic studies, history, social anthropology, pharmacy and agriculture. The approaches are based on textual analysis, empirical research and laboratory experiment. Both historical and contemporary issues are covered. Contributors include: Mohammed Al-Duais, Jacques Fleurentin, Amin Al-Hakimi, Ingrid Hehmeyer, Gottfried Jetschke, Efraim Lev, Ulrike Lindequist, Miranda Morris, Ester Muchawsky-Schnapper, Frédéric Pelat, Mikhail Rodionov, Petra Schmidl, Daniel Martin Varisco and Anhar Ya’ni.
