Learning unit contents

Part 2 of the pharmacognosy course will be dedicated to the study of toxic and psychotropic plants, as well as plants used in phytotherapy, all within the context of Evidence-Based Medicine, in connection with the recommendations of the EMA (European Medicines Agency). One chapter will also focus on medical cannabis, and another on essential oils (aromatherapy).

At the end of this course, with regard to phytotherapy, the student will need to distinguish between the various pharmaceutical forms based on natural raw materials (powdered raw material, dry extracts, tinctures...), as the concentrations of active ingredients differ significantly and will not only influence the biological effects but also the analytical methods. The student will also be capable of distinguishing between different phytotherapy products available in pharmacies based on their status, as well as their effectiveness and safety.

Learning outcomes of the learning unit

After the course, the future pharmacist should:

- know the main plants used in phytotherapy in Belgium (scientific name, part used, use, method of use).

- be able to distinguish the different statuses of phytomedicines present on the market in Belgium.

- know the main toxic and psychoactive plants in our environment.

- be able to recognize the main phytochemical classes present in medicinal plants, and their properties.

- be able to distinguish the differences between the different pharmaceutical forms (powder, extracts, herbal tea, ...) used in phytotherapy.

- Interpretate a leaflet of a phytomedicine and a monograph of the EMA (preparations to be used, indication, dosage...).

Prerequisite knowledge and skills

Organic chemistry
Analytical Chemistry (particularly practicals)
Pharmacognosy (Partim I)

Planned learning activities and teaching methods

1/ Ex-cathedra courses (or remote courses as podcasts):

2/ Practicals: Identification of some medicinal plants described in European Pharmacopoeia ( macro- and microscopical examinations) and seminars about their use in medicine Laboratory of pharmacognosy (3d floor of Pharmaceutical Institute)

Schedule: Wednesdays :from February (in series).

Attendance during practical work is mandatory.

A non justified absence at a controle session will lead to a note of "zero" for this session that will be used in the final mean note. An attendence rate below 80% or a non-justified absence at the final exam could lead to no admissability at the final exam. 

In case of justified non-attendance leading to an attendance rate below 80%, the teachers reserve the right to take any action they judge necessary in order to allow the students to catch up the session(s).

All certificates have to be transmetted to the assistants not later than 3 days after the absence (email accepted).

3/ interactive Seminars (mandatory).

Mode of delivery (face to face, distance learning, hybrid learning)

Blended learning

Exam(s) in session

Any session

- In-person

oral exam

Out-of-session test(s)

Additional information:

Oral examination about definite matter. Practicals: 10% of total for microscopy and vegetal drugs recognition will be included in oral exam  (1st and second session). A not justified absence during practicals or the microscopy exam could lead to be refused at the oral exam.

The TP grade will be kept for the second session.


Reminder: Attendance at practical work is mandatory. Consequently, in conformity with article 40 of the general exam rules, a level of absenteeism that is too high may result in students being prohibited from sitting the exam.

Work placement(s)

Possibility of internship. Student instructor: possibilities are offered for students interested in teaching pharmacognosy. The tasks consist of supervising practical work. Research: outside of class and examination periods (from the end of block 2 of the Bachelor in Pharmaceutical Sciences), motivated students can do an internship in the laboratory (student-researchers). At the end of the course, a PhD is possible in the service.
