Assessment
Unaided Work:
1. Individual work with herbaria, crude herbal drugs and their adulterants. The ability to recognize plants, crude drugs, their adulterants is tested in colloquiums (oral) and in an exam (written). 2. Preparing for the control tests and colloquiums (using materials posted in e-studies; protocols of practical classes). The acquired knowledge, skills and competencies are regularly tested in the semester examinations, in the final examination of the study course – in the exam and in the state examination. In order to evaluate the quality of the study course as a whole, the student must fill out the study course evaluation questionnaire on the Student Portal.
Assessment Criteria:
Regular attendance of practical classes and active participation in laboratory works (pass). Demonstration of good results (4–10 points) during weekly tests, colloquiums (forms an accumulative assessment of the acquired course; its share in the overall assessment of the exam – 50%). Demonstration of good results of spring and autumn semester tests (pass). Evaluation of the quality of prepared crude herbal drugs and herbaria (1–10 points; its share in the overall assessment of the exam – 16.666...% ). The ability to recognize plants, crude drugs, their adulterants is tested in colloquiums (oral; evaluation in a 10-point system) and in an exam (written; evaluation in a 10-point system; its proportion in the written part of the exam – 50%). Proportion of the written part of the exam in the total assessment – 33.333 ...%.
Final Examination (Full-Time):		Exam (Written)
Final Examination (Part-Time):		Exam (Written)
Learning Outcomes
Knowledge:		Upon completion of the course the students will know: • criteria for the recognition of herbal drugs in the European Union; • appearance of medicinal plants, their name in English and Latin, the most significant differences from their adulterants (similar plants); • appearance of crude drugs and products obtained from medicinal plants and animals; their name in English and Latin; the most significant differences from their adulterants (similar drugs); • the properties of biologically active herbal and animal substances; • conditions of herbal drug preparation and storage; • the use of crude drugs and products obtained from plant and animal in scientific medicine, their role in maintaining and/or recovering health.
Skills:		Upon completion of the course the students will be able to: • recognise medicinal plants and distinguish them from adulterants; • recognise crude drugs and products obtained from plants and animals and distinguish from their adulterants; • determine identity and purity of crude drugs obtained from plants and animals during macroscopic and microscopic examination, physical and chemical methods of analysis; • explain usage of herbal and animal remedies in scientific medicine.
Competencies:		Upon combining theoretical knowledge and practical skills, the students will be able to: • ensure qualitative process of preparing crude drug; • evaluate identity and purity of plant and animal origin crude drugs and products; • evaluate the importance of plant and animal origin crude drugs and products in scientific medicine.
