Since Buddhism was introduced to China, medicine from India and Central Asia was also introduced to China along with cultural and commercial exchanges. During the Tang Dynasty, some Indians and Persians who stayed in China specialized in medical practice. Medical officials in the Tang Dynasty naturally enriched the Chinese pharmacopoeia with these fresh and effective new drugs. Since the Tang Dynasty, Chinese medicinal herbs such as ginseng, poria, angelica, polygala, aconite, aconite, ephedra, asarum, etc. have also been used to treat diseases in Central Asia and Indians. The editors of "Tang Materia Medica" not only added new types of medicines, but also carefully corrected the medicines that were wrongly recorded in "Shen Nong's Materia Medica". They found that the number of medicines that Tao Hongjing had wrongly recorded more than 100 years ago was actually as many as More than 400 species! This made cautious people afraid to even use the prescriptions of this pharmacologist who was extremely passionate about alchemy. However, it is understandable that a group of rising stars should correct the mistakes of an ancestor who worked alone.
