Objectives
Acquisition of knowledge on the plant origin, morphology, chemical composition, biological activity and use of herbal drugs and derived preparations. The student, on the basis of the acquired skills, will be able toelaborate criteria to recognize and use the herbal drugs.
Acquision of knowledge on plant metabolism, with particular attention to plant secondary metabolites. The student, on the basis of the acquired skills, will be able to understand and correlate the main classes of natural products.
Prerequisites
PLANT BIOLOGY, PHARMACEUTICAL BOTANY,ORGANIC CHEMISTRY, AND BIOCHEMISTRY

Teaching Methods
LECTURES, SEMINARS, TUTORIALS
Verification of learning
THE EXAMINATION CONSISTS OF A WRITTEN AND ORAL TEST, TO BE SUSTEINED IN THE SAME EXAM SESSION. THE RATING IS X/30. PASS THE WRITTEN TEST WITH A SCORE OF 18/30, IT IS MANDATORY TO BE ABLE TO TAKE THE ORAL TEST, AND REACH THE FINAL GRADE. THE WRITTEN TEST TAKES TWO HOURS AND CONSISTS OF OPEN QUESTIONS ON THE MAIN LEARNING OUTCOMES.
THE STUDENT WILL BE ASKED TO DISCUSS THE MAIN TOPICS OF THE COURSE, TRYING TO DEMONSTRATE CRITICAL THOUGHT AND AWARENESS OF THE STRUCTURE OF THE FIELD OF STUDY.
