PHARMACOGNOSY AND PHYTOTHERAPY

Course objectives

The general objective of the course of Pharmacognosy and Phytotherapy is to provide the student, at the completion of the course, the concepts concerning the composition and effects of “drugs” (biologically active substances of natural origin), their preparations and the active ingredients contained in them. The student, based on the acquired skills, will thus be able to correctly use natural products in the therapeutic field, as well as dietary supplements or in the pharmaceutical industry. These objectives will be achieved through the co-ordinated integration of lectures and practical activity of comparison and analysis, in which particular attention is devoted to the effectiveness and safety of use of herbal preparations. Specific objectives of the course of Pharmacognosy and Phytotherapy are the acquisition, by the student, of transversal skills, related to detailed knowledge of different aspects of herbal drugs. In particular: their morphological characters, identification methods, possible sophistication, chemical composition, the pharmacological activity, the practical uses, the possible pharmacokinetic and / or pharmacodynamic interactions with drugs, foods, etc. and any undesired or toxic effects. The skills that will be acquired, also through classroom exercises dedicated to specific insights, concern the exercise of critical skills and judgment on the real effectiveness and safety of use of commercial products containing medicinal plants. These skills will contribute to the preparation by the student, not only to communicate what has been learned, but also to continue the study and the related in-depth analysis of the subject. The communication skills and the applicative autonomy (in the real life) of the concepts learned and the related objectives achieved, will also be made possible by the tools that will be provided to the student during the course, including scientific documentation to refer to, institutional and non-profit scientific associations websites, industry databases, etc., in addition to reference teaching texts.

Course program
The syllabus (10 CFU; 80 h) is divided into two main macromodules: Pharmacognosy (Module 1) and Phytotherapy (Module 2), which are each one further divided into two submodules a and b. In the Module 1a (20 h), the general aspects of Pharmacognosy and issues related to natural products are addressed, with particular focus on factors affecting the variability of natural products, preparation of herbal drugs, quality control, and bioequivalence. Module 1b (20 h) covers the characteristics of the phytochemicals of herbal drugs, their pharmacological properties, and risks of toxicity, with examples of medicinal plants containing them. Module 2a (32 h) describes different merchandising categories of natural products (e.g., herbal medicines, plant-based supplements, herbal products, medical devices), with references to regulatory aspects governing their marketing and their application in phytotherapy for specific mild/moderate pathologies. Lastly, Module 2b (8 h) addresses general issues related to the safety of using herbal drugs and natural products, potential adverse reactions associated with their use in phytotherapy, and in combination with drugs or food.

Class attendance is recommended. In fact, the lectures will allow the student not only to acquire specific knowledge but also to develop communication skills and technical language through the interaction in the classroom with the lecturer on topics related to the course. The student will also be stimulated to formulate judgments and to critically evaluate the challenges and problems about the topic under study, particularly the herbal drug quality, the rational use and the possible adverse reactions.
Exam mode
Learning achievements will be evaluated through an oral exam, during which the student will be asked to describe and critically discuss the topics covered by the syllabus and covered during classroom. The exam can be passed if the score is greater than or equal to 18/30. To achieve the minimum score, the student must demonstrate to that sufficient knowledge of the general problems of Pharmacognosy and plant drugs, and of natural compound characteristics and on the use of medicinal plants in phytotherapy, with particular reference to rational use and safety problems of use, have been acquired. To achieve a score of 30/30 cum laude, the student must instead demonstrate that excellent knowledge of all the topics covered during the course and logical abilities have been acquired. A voluntary written self-assessment test may be proposed at the end of the course, upon agreement with the instructor, to help students verify their level of preparation and guide them in view of the final oral exam.

Prerequisites
The student must not have to absolve particular prerequisites. However, in order to better understand some specific concepts (e.g., drugs containing alkaloids, mechanism of action of medicinal plants, phytotherapy of specific diseases) and to more easily achieve the learning objectives, it would be important to know subjects such as: human anatomy, general physiology, biochemistry and general pathology. It could also be useful to study (at least at the same time) general and molecular pharmacology. Where the student cannot attend the lessons, he/she must absolutely inform himself of what was made available and/or reported by the teacher, as material useful for learning purposes. The above mentioned must not be considered as an indispensable obligation, but as a prerequisite recommended to optimize the successful passing of the exam, to be taken at the end of the course.
Books
- Farmacognosia e Fitoterapia. Basi farmacologiche e aspetti applicativi. Mazzanti G., Dell'Agli M., Izzo A.A. Ed. Piccin (2020). - Farmacognosia – Botanica, chimica e farmacologia della piante medicinali. Capasso F. II° Ed. Springer-Verlag (2011). - Fitoterapia – Impiego razionale delle droghe vegetali. Capasso F., Grandolini G., Izzo A.A. Ed. Springer (2006). In order to help the student in terms of method and continuity in the study, the distribution of the recommended texts along the duration of the course could be hypothesized as follows: Text 1 is useful for carrying out the entire program of the course and can be effectively integrated with the notes taken in class and with the sitography and / or other specific bibliography, recommended by the teacher (see sites and references reported in the "Reference Bibliography" section) The texts 2 and 3 are useful if they are integrated with each other. Text 2 for the general part of the program (see points 1 and 2 of the same, in the appropriate section "teaching program"). Text 3 is more useful for the special part (see point 3 of the program) relating to the phytotherapy of specific mild / moderate diseases.
Teaching mode
The adopted teaching method provides (for the greater number of hours), in accordance with any measures relating to the management of emergencies, lectures. However, exercises, related to the analysis of case reports of Phytovigilance and the simulations of bibliographic research in the drafting of papers, through the use of telematic supports (specific to the field of pharmacognosy and phytotherapy) are also foreseen. The course will in any case depend on the teaching method, allowed by the COVID19 emergency. The teaching methods, chosen by the teacher, contribute not only to the achievement of the planned training objectives, but are also methods easily usable in the real working life, as they provide quick and free access to databases and websites of the medicinal plants sector and its uses and warnings.
Frequency
Course attendance is mandatory. The teacher will check the presence in the way it deems most appropriate. The frequency is useful as it allows to obtain updated information, not necessarily available in textbooks and, above all, helps to achieve a valid method of approach to the study of the subject.
Exam mode
The actual achievement of the expected learning outcomes by the student, in accordance with the training objectives, is evaluated through an oral exam. Among the aspects that contribute to the formation of the final judgment, beyond the specific preparation of the student on exam topics, is also evaluated the reasoning ability and the study that has conducted in an autonomous way, not based only on the mnemonic abilities. The duration of the test, as an oral one, is difficult to define and depends essentially on the degree of preparation and the student's exhibition skills. An average duration of about 20 minutes is conceivable. The teaching, as established by Manifesto, does not provide intermediate tests but only tests at the end of the teaching course. These tests have pre-established dates and are communicated annually to the Secretariats and published via e-learning and via Infostud. To pass the exam it is necessary to achieve a grade of not less than 18/30. The student must demonstrate that he has acquired sufficient knowledge of the general and special topics and that he is able to provide useful application advice concerning the use modalities, warnings, undesired effects, interactions of the products containing medicinal plants. To achieve a score of 30/30 cum laude, the student must instead demonstrate that he has acquired excellent knowledge of all the topics covered during the course (including the most recent ones covered during the course), being able to link them in a way logical and consistent.
Bibliography
The reference bibliography reported below can be used in the part related to the in-depth analysis (point 4) and/or more current topics. It should however be specified that the preparation of the student should not be sectorialized, but must provide the reasoned capacity for the integration between the different parts of the program, in the different sources of information.

The adopted teaching method provides (for the greater number of hours), in accordance with any measures relating to the management of emergencies, lectures. However, exercises, related to the analysis of case reports of Phytovigilance and the simulations of bibliographic research in the drafting of papers, through the use of telematic supports (specific to the field of pharmacognosy and phytotherapy) are also foreseen. The course will in any case depend on the teaching method, allowed by the COVID19 emergency. The teaching methods, chosen by the teacher, contribute not only to the achievement of the planned training objectives, but are also methods easily usable in the real working life, as they provide quick and free access to databases and websites of the medicinal plants sector and its uses and warnings.
