[Transmission and development of foreign medicinal materials in the Tang and Song Dynasties]

Many foreign medicinal materials that were imported to China via the Silk Road and maritime trade have enriched Chinese medicine. Imported foreign medicines reached a high point by the Tang and Song Dynasties, particularly in the case of aromatic medicines, which supplemented domestic Chinese aromatics and were widely employed in official dispensaries in the Song Dynasty. This study investigated historical records related to imported Chinese medicines in the Tang and Song periods, focusing on their varieties, quantity, use, and localization trends. Foreign medicines were assimilated as Chinese medical theory was applied to interpret their effects, and aromatics such as frankincense that were extremely expensive in the Tang Dynasty became accessible to common people by the Song Dynasty. By the Song Dynasty, some foreign medicines began to be domestically cultivated and the boundary between foreign and traditional Chinese medicines became blurred; foreign medicines gradually transformed into Chinese medicines. The importation of foreign medicines during the Tang and Song Dynasties was a historical turning point that contributed greatly to the development of traditional Chinese medicine.
