[Study on the image of fragrant plants in Wood section of Compendium of Materia Medica].

As a representative work of materia medica in the Ming Dynasty, the plant images attached to Compendium of Materia Medica retain the results of Li Shizhen's research on the original plants of medicinal materials in another form, which truly reflects the understanding and utilization of herbs in the Ming Dynasty.Taking the image of fragrant plants in Wood section in the book as an example, the original of the plants depicted in the images is examined to reveal the level of understanding of plant knowledge and medicinal properties in the Ming dynasty.Among the 25 images contained in the woody section, 20 images accurately depict the leaves, flowers and fruits of plants, and the description of the morphological details of the plant Cephalotaxus fortunei Hook. f. proves a high level of understanding of plant morphology and medicinal properties at the time. However, the errors of a total of 5 diagrams such as Wuyao and A wei also showed limitations. By comparing the results of the image with the medicinal properties contained in the text,it is clear that the level of understanding of medicinal properties is very high in the Ming dynasty, and the understanding of the medicinal properties of some plants is even higher than the understanding of their morphology.
