2 Introduction to the splendid civilization and long history of traditional Chinese medicine: Chinese medicine has a long history. It has been created since Shennong tasted all kinds of herbs and has continued for thousands of years. From the first book on traditional Chinese medicine recorded in history "Nei Jing" to "Shen Nong's Materia Medica" and "Treatise on Febrile and Miscellaneous Diseases" of the Eastern Han Dynasty, from Tao Hongjing's "Compendium of Materia Medica" and "Famous Doctors" written by Tao Hongjing's predecessors to "Qian Jin Prescription" by Sun Simiao, the king of medicine in the Tang Dynasty. , from the "Illustrated Materia Medica" written by Su Song in the Northern Song Dynasty to the "Compendium of Materia Medica" written by Li Shizhen, we can clearly see the rich and mature development context of Chinese medicine. The national medicine treasure ---- donkey-hide gelatin was bred and produced in this great treasure house of Chinese medicine. Starting from the earliest record of donkey-hide gelatin in the "Shen Nong's Materia Medica", great medical scientists and medical classics of the past dynasties have discussed donkey-hide gelatin. Along with ginseng and deer antler, it is also known as the three treasures of traditional Chinese medicine, which shows the special status of donkey-hide gelatin in traditional Chinese medicine.
