Pharmacognosy, the study of nature-derived pharmaceuticals and poisons, has been a foundational science in pharmacy education for over two centuries. Its importance has grown significantly in the last 20 years due to the proliferation of new drugs, phytomedicines, nutraceuticals, and dietary supplements, all requiring thorough understanding, testing, and regulation. This textbook offers insights into the history, botany, chemistry, and phytotherapy of medicinal plants, integrating traditional pharmacognosy with modern phytotherapy.
