This paper is mainly on the rsearch of the prescriptions of "Sanbeon-bang(刪 繁方)". For the research of prescription, investigated "Sanbeon-bang" from the side of symptoms of a disease, number of drugstuffs, table of contents, drugstuffs and acupuncture and moxibustion. With these investigation, made out a few tables, and with these tables made an attempt to understand the whole prescriptions of "Sanbeon-bang". "Sanbeon-bang" is of rich contents in internal medicine. Among internal medicine, related to Oro-Yukgeuk-Chilsang(五勞-六極-七傷) was most abundant. So we can guess "Sanbeon-bang" was a medical book specialized in exhaustion syndromes. It also deals with the Samcho-syndromes, as investigate from medical comments, has the perfect system of prescription in relative. From the investigation of the combination of drugstuffs, ascertained that, the number of simple prescription composed of one drugstuff was 38, combinational prescription composed of two drugstuffs was 9, minor prescription composed of three to five drugstuffs was 47, midum prescription composed of six to ten drugstuffs was 95, major prescription composed of eleven to twenty drugstuffs was 45, and mixed prescription composed over twenty drugstuffs was 1. Mentionable unique prescriptions in internal use were the forms of keeping in mouth. In external use they were fumigants, suppositories, powdered medicines, spraying the granular medication into the nasal cavity and eyedrops. And were abundant in soft extract(ointment) and plaster. In addition, there were the recordings of 18 types of cellulitis, types of incurable cellulitis and curing an illness by a charm. By the way, when comparing "Sanbeon-bang" with "Cheongeum-bang", all of which was quoted a lot in "Oedaebiyo-bang", "Cheongeum-bang" rather took medical comments of "Sanbeon-bang" than prescription. Although there were some prescriptons in "Sanbeon-bang" at the same category, "Cheongeum-bang" took another prescriptions which are more complexed than those of "Sanbeon-bang". In the same way, when comparing "Cheongeum-bang" with "Sonjinin-Cheongeum-bang(孫眞人千金方)", which didn't go through the correction of GyojeongUiseoguk of Bug-Song goverment, "Cheongeum-bang" often didn't take the prescriptions of "Sonjinin-Cheongeum-bang". Hence we can guess, "Cheongeumyo-bang" may have added a lot of prescriptions when undergoing the correction of of GyojeongUiseoguk. The total number of species of drugstuffs in "Sanbeon-bang" from the investigation was 284. The plant drugs were 208 species, the animal were 31 species, the minerals were 19 species and the other were 26 species. The prescriptions related to acupuncture and moxibustion in "Sanbeon-bang" were only moxibustional prescriptions. Which appeared one time per exhaustion and steaming of bone syndrome, Oro-Yukgeuk-Chilsang and Samcho syndrome. Appeared six times in muscle syndromes. But I cannot imagine the original form of acupuncture and moxibustion in "Sanbeon-bang" for deficiency of data.
