Topic

Pharmacognosy covers general aspects of medicinal plants (such as industrial applications, research, cultivation and cultivars, gene technology, critical evaluation of holistic medicine and homeopathy, possibilities of phytotherapy) and discusses the chemical composition and other qualitative characteristics, as well as the most important areas of usage and pharmacology of herbal drugs and drug fractions such as oils and essential oils. Based on their previous pharmacobotanic knowledge students become acquainted with medicinal plants and drugs that are used in pharmacotherapy (especially in phytotherapy) both in Hungary and abroad. Students are required to recognize the most important tea drugs and drugs with strong physiological effect that are traded and/or imported in Hungary. In the frame of practices students obtain experience in drug analysis and identification methods and the ability to solve daily arising problems, with special emphasis on processing information from literature, databases and the internet.
Course objective and role in the curriculum: students should become familiar with plant materials and drugs, as well as their effective substances in general. During the practices, macroscopic and microscopic examinations of the drugs are organized.
