This course is of special importance in the professional training of the pharmacist, since the Pharmacognosy subject deals with the study of medicinal plants, and products obtained from them, in all their aspects, from their obtention, quality, chemical composition, to their pharmacological actions and uses.
Its objectives are:
- Provide students with a vision of the isolation of active ingredients from natural products
- Train students in the recognition of plants through microscopic and phytochemical methods
- Relate the effect of the active principles of natural products with their therapeutic applications

Throughout the course, and always through the subject of the VIRTUAL CAMPUS of the USC, the student will follow at all times the guidelines indicated by the professors, for the good coordination and development of the subject.
Expository classes:
Presentation, for 1 hour, of the fundamental concepts of the subject matter, using the necessary didactic elements (videos, presentations, etc.).
Interactive classes:
Face-to-face classes in which theoretical knowledge will be applied when dealing with hypothetical situations within the framework of this discipline. Its purpose is to encourage analysis and discussion on a given issue to which a solution must be proposed.
Practical classes:
On-site practices in the laboratory for natural drugs recognition, both from the microscopic point of view (observation and diagnosis of drug powder preparations included in the Spanish Pharmacopoeia) and phytochemical (isolation and identification of some of the main phytochemical groups to which they belong the active ingredients).
To pass the subject it is necessary to carry out and pass the laboratory practices.
Evaluation of theoretical knowledge (60% of the final grade).
An exam will be held on the day indicated in the official exam calendar drawn up by the School of Pharmacy. The test will consist of a batch of several questions with different possible answers each, of which only one is valid. Wrong answers will have a penalty; the unanswered ones, no. The teacher will inform the students of the minimum grade required in this exam in order to pass the subject (it will depend on the number of questions in the test). The maximum mark attainable in this section is 6 points.

The final mark will be the sum of the marks obtained in each of the evaluations mentioned above (10 points, maximum). In case of not reaching the minimum mark required in the evaluation of theoretical knowledge, the final mark will be the sum of the grades obtained in the practical evaluations and continuous evaluation and interactive classes (15% + 25% of the final grade).
Individual study 60 hours.
Resolution of exercises 20h.
Prepration of the practices examination: 6h.
Recommendations for evaluation.
Attendance at the expository and interactive classes is recommended, since in the latter a series of questions and exercises will be made that will facilitate learning of the subject.
Recommendations for recovery.
Students are recommended to discuss the results of their exams with the teacher, clarify their doubts and review their notes.
Repeating students
The qualification obtained in the laboratory practices and in the continous avaliation may be maintained for those repeating students who wish to do so; they must ask the teacher for the validation of the internships they carried out in previous courses, before they begin.
Students with exemption from class attendance
Your final grade will not be affected by this fact, although carrying out the laboratory practices is essential to pass.
For cases of fraudulent completion of exercises or tests, the provisions of the "Normativa de avaliación do rendemento académico dos estudantes e de revisión de cualificacións" will apply.
