Ethnobotany is a scientific research field that chronicles indigenous plant knowledge and compiles a list of useful plants among local ethnic communities. This research concentrates on plants used in traditional remedies throughout several countries. Ethnobotany has expanded beyond plant studies to include algae, lichens, and fungi. It is intimately linked to taxonomy, pharmacognosy, phytochemistry, ecology, and conservation biology. Ethnobotanical approaches have resulted in the development of several useful drugs. This review will address ethnobotanical research undertaken in India.
