2) To remember the botanical name of the plants.
3) To acquire preliminary pharmacokinetic and pharmacodynamic notions for understanding the pharmacological activity of natural substances.
4) To know the pharmacological activity of the main natural molecules and their mechanisms of action.
5) To Acquire ability in using the specific language of the discipline.
Knowledge and understanding applied skills
1) To apply the knowledge of the mechanisms of action of the natural molecules to define their pharmacological activity and use.
1) To evaluate the validity of a phytotherapy product in independent manner.
1) Possess the ability to synthesize information and effectively communicate it to specialists and non-specialists.
1) Develop skills and methodology that will allow you to study in a highly indipendent manner.
2) Updating the knowledge through the consultation of scientific databases
There are not prerequisites. However, the following exams are highly recommended: Human anatomy/animal biology

The lessons will be mainly frontal, but will be complemented by online bibliographic research in order to provide students with the ability to know reliable databases from which to obtain information on phytotherapy products.
The slides used to support lessons, as an integral part of the teaching material, will be uploaded weekly on the Elly platform.
In the event of a protracted health emergency, mixed teaching will be adopted, with lessons organized in person and with the possibility of synchronous use even remotely (via Teams). Guide to using the Teams platform available at: https://selma.unipr.it/
In this case, lessons will also be carried out in asynchronous mode, and made available on the Elly page of the course. https://elly2020.saf.unipr.it/
Assessment methods and criteria
Oral examination, to be performed together with Plant Biology (as single exam).
Oral testing to be supported at the same time as the Plant Biology module (they are a single exam, both modules must be sufficient to overcome it).
Scale of assessment: 0-30
Weights and evaluation criteria:
1) Acquired knowledge (up to 15/30);
2) Ability to apply the acquired knowledge and to make connections between the covered topics (up to 10/30);
3) capacity to communicate concepts through the use of the specific language of the discipline (up to 5/30).
For Erasmus students: written test with 15 multiple choice questions. There is no penalty for incorrect answers
If due to the persistence of the health emergency it is necessary to integrate with the remote modality the execution of the exams will take place as follows: remote oral exam (free conversation) using the Teams platform.
Upload of the identification document in a One Drive folder shared by the teacher, to be deleted at the end of the exam.

In the event of a protracted health emergency, the reception will take place remotely using the Teams platform
