Objectives: The purpose of this study was to investigate the external application of paste preparation recorded in the Annals of the Chosun Dynasty (朝鮮王朝實錄) and to clarify the significance of modern use of plaster therapy. Methods: Of many paste preparations, records of All-applying ointment (萬應膏), One-great ointment (太一膏), Pain-relieving plaster (救苦膏), and Pus-promoting powder (促膿膏) were especially examined from the Annals of the Chosun Dynasty. Other medical records regarding how these preparations were passed onto later generations were also studied. Results: According to the records from the Annals of the Chosun Dynasty, paste preparations were mainly used to cure abscess and sore, partly to treat pain diseases. From other medical documents, it could be found that these preparations were continuously used in subsequent eras. Conclusions: From these records, the level and features of Chosun Dynasty medicine could be speculated. It is necessary to find and restore effective paste preparations in Traditional Korean Medicine to use for treating disease today. Therefore, records from the Annals of the Chosun Dynasty are important and meaningful materials.
