Yaksanhogojongbangchwalyo(若山好古腫方撮要) is a medical text written by Kang I-o(姜彝五). It is known as a handwritten manuscript focusing primarily on surgical treatment methods. Since no prior research has explored the pharmacological poems(Yakseongga, 藥性歌) included in this book, this study examined them. By comparing the pharmacological poems found in Jejungsinpyeon(濟衆新編) and Yaksanhogojongbangchwalyo, I aimed to identify the characteristics and unique features of the pharmacological poems in Yaksanhogojongbangchwalyo. In this book, effective medicinal materials are listed for each disease, followed by explanations of treatment methods using those materials. At the end of the book, a collection of pharmacological poems is appended. There are a total of 324 pharmacological poems in the book, but when duplicates are excluded, there are actually 321. These poems follow the format of four characters per line, four lines per verse, and largely derive from the pharmacological poems in Jejungsinpyeon. In Jejungsinpyeon, pharmacological poems are categorized into Chinese medicines(唐藥) and native Korean medicines(鄕藥), and 276 poems include the Korean names for the native medicines. On the other hand, in Yaksanhogojongbangchwalyo, 73 poems include information on the meridian entry, efficacy, and indications of the medicinal materials, but no distinction is made between Chinese and native medicines; instead, the Korean names are recorded for 22 medicinal materials. Most of the content about the medicinal drugs' attributive channel was confirmed to be based on the Donguibogam content. When compared with Jejungsinpyeon, many cases show that the descriptive properties of the drugs have had the cold nature, and sweet taste added or removed, but there was no case where the cold nature was deleted. This can be seen as a modification of the medicinal properties to effectively utilize the drugs for treating the specific diseases covered in the specialized book on abscess treatments.
