Pharmacognosy is the study of medicinal drugs derived from natural sources, including plants, animals, and microorganisms. It explores the biological, chemical, and physical properties of these natural substances, focusing on their potential therapeutic applications. The course covers topics such as the classification, identification, extraction, and isolation of bioactive compounds, as well as their pharmacological effects and mechanisms of action. It integrates knowledge from botany, chemistry, and pharmacology to understand how natural products contribute to modern medicine. Students also learn about traditional medicine, ethnopharmacology, and the role of natural compounds in drug discovery and development. The course often includes laboratory work to develop practical skills in analyzing and testing medicinal plants and other natural sources. Pharmacognosy plays a crucial role in pharmaceutical sciences, bridging the gap between traditional remedies and scientifically validated medicines.
