Abstract: In view of situations that the theory and practice of pharmacognosy are partially disconnected, and students lack the ability to solve practical identification problems, an online and offline blended teaching mode combined with case analysis is adopted to realize the in-depth exploration of the characteristic medicinal materials. Driven by local serving and industrial demand, a multi-dimensional and multi-channel comprehensive identification strategy of regional genuine medicinal materials is systematically connected. And the students'rational and perceptual understanding of the“authentic, fake, superior and inferior”of crude drugs is enhanced through independent learning and cooperative discussion. Ultimately, it achieves the goal of students'integrated quality evaluation of regional genuine medicinal materials, form a new teaching model for pharmacognosy courses that solidifies the foundation and hones skills.
