Medical Degree Program in China - Pharmacognosy
1. Introduction
Pharmacognosy refers to taking crude drug as the main object of study, including the name, origin, production (cultivation), sampling (acquisition, processing, processing), identification (authenticity identification and quality evaluation), chemical constituents, medical uses, organization culture, development and utilization of resources of the crude drug and creating new drug. In other words, pharmacognosy is the discipline using herbal medicine, botany, zoology, chemistry, pharmacology, medicine, molecular biology and other knowledge to study the application of natural medicine. Generalized crude drug shall mean all from natural raw materials, including the Chinese herbal medicine, folk herbal medicine, folk medicine and raw materials that can be used for the extraction of chemical drug. In short, the crude drug is the natural herb.
2. Main Tasks
Study the varieties and sources of crude drug, to ensure that the source is real
Study the effective ingredients of crude drug and its identification, to ensure good quality
Study crud drug resources and the sustainable development and utilization
3. Learning Methods
Pharmacognosy is an important professional course in Chinese pharmacy, which has close relationship with pharmaceutical botany, natural medicinal chemistry, pharmacology of traditional Chinese medicine and natural medicine, Chinese medicine course. Because the crude drug are mostly from medicinal plants, so botany is one of the most important foundation courses of pharmacognosy.
Study pharmacognosy should contact reality, in addition to learn the basic theory and knowledge outside, but also attaches great importance to practice teaching and experimental operation, often identify outdoors or in medicine warehouse, in the herbarium (room) and laboratory, having more observation and comparison, various kinds of medicinal botanical and pharmacognostical standard the morphological characteristics, find out their similarities and differences, and then master the content of textbooks and classroom teaching or other reference books, so as to enhance mutual understanding and impression, to master the contents of books. Avoid rotting, usually more observation, comparison, experiment, practice, integrate theory with practice, in order to learn flexibly, learn well and apply what they have learned.
