Introduction to Pharmacognosy: As per New PCI Syllabus 2026

Natural medicines remain important sources of therapeutic agents, pharmaceutical leads, and traditional healthcare materials, but their scientific use depends on correct identity, quality, processing, and evidence-based interpretation. Introduction to Pharmacognosy develops these foundations for first-year B.Pharm students in accordance with the new PCI Syllabus 2026.The book progresses from the definition, history, scope, natural sources, and landmark drug discoveries to herbal pharmacopoeias and crude-drug classification. It then covers cultivation, collection, processing, storage, plant hormones, plant improvement, conservation, value addition, and eco-pharmacognosy, followed by adulteration, pharmacognostic evaluation, physicochemical parameters, and DNA barcoding. Primary and secondary metabolites, AYUSH, TCM, and prescribed phyto-therapeutic agents complete the progression from fundamentals to application.The presentation emphasizes cause-and-effect relationships, quality-control reasoning, precise pharmaceutical terminology, and clear distinctions among biological identity, chemical quality, traditional use, and scientific evidence. Phyto-therapeutic agents are organized by biological source, major constituents, and uses to support systematic learning and revision.Its concept-to-application structure provides a sound foundation for later study of natural products, phytochemistry, herbal quality control, and pharmaceutical sciences.
