Résumé fourni par la source

Pharmacognosy is a fundamental branch of pharmaceutical science that recognizes and uses natural products with therapeutic potential, originating from plant, animal, marine, and microbial sources. This chapter examines the evolution of pharmacognosy from its ancient origins in medication to the modern scientific era. Some covered areas include the sources and isolation of bioactive agents, the preparation of pure compounds, and the development of contemporary drugs concerning their natural origin. The benefits of pharmacognosy are discussed in terms of its impact on medical science, including drug development, preservation of plant resources, and mainstream use of traditional knowledge systems. To explain the features and prospects of pharmacognosy, this chapter focuses on the separate branches of pharmacognosy–analytical, chemical, ethnopharmacological, and marine–to emphasize the significance of natural products in therapeutic sciences.
