This work analyzes the difficulties and limitations of medical plant training, investigates and studies the suggestions of the teachers and students of traditional Chinese medicine colleges and universities and Chinese medicine lovers on the practical training, combining with virtual reality technology, using Unity3D simulation to reproduce the real medical plant training scene, to realize the intertemporal and temporal learning of the function and taste of traditional Chinese medicine, to understand the characteristics of traditional Chinese medicine, to understand the growth environment of medicinal materials, to distinguish the characteristics of medicinal materials and to identify their characteristics, and to collect the whole strains of traditional Chinese medicine or the sites of medicine. In order to enhance the interest of learning, four-season variation, diurnal alternation, and different weather are added to optimize the environment. In addition, different environments can publish tasks and complete tasks in the form of games for reward. Applying virtual reality to practical teaching training can improve learning efficiency, increase professional knowledge, cultivate self-rescue ability, effectively exercise the safety consciousness of users, and reduce the occurrence of safety accidents.
