Contribution:
In content, The Newly Revised Materia Medica is also outstanding. Because it was the heyday of the Tang Dynasty, economic and cultural exchanges between China and foreign countries were very active, and many foreign drugs entered China through trade, such as benzoin, borneol, pepper, terminalia chebula, turmeric, fennel and Ferula.
Due to its rich content, the newly revised Materia Medica spread immediately. It was first spread by Japanese monks who came to China to seek dharma at that time, which had a great influence on Japanese medical circles and soon spread to North Korea and other countries.
