Objective : Blood disease is common these days due to modern man's excessiveness in Yang heat (陽熱) and vulnerability of the Eum blood(陰血). This exposes them to warmheat/ dampness-heat diseases, where pathogenic heat easily penetrates the blood dimension(血分) creating stagnated blood(瘀血). Consequently, pathogenic symptoms in the collateral vessels increase, making it crucial to understand the pathogenic mechanism of the disease. Method : This paper examines the condition and region of the collateral vessel diseases(CVD) according to the blood diseases of Onbyeong, by analyzing each prescription's matching symptom. The disease in question in this paper is 'stagnated blood fixated in the collateral vessels'. Therefore diseases with stagnated blood in the Yang collaterals and Viscera collaterals or viscera themselves from the chapter of "On-Yeok-Ron(溫疫論)", and < Dry Blood-DaeWhangJaChungWhan(大黃蟅蟲丸) > chapter of "Geum-Gue-Yo-Rak(金匱要略)", were examined respectively. Result & Conclusion : The process of CVD according to the blood diseases of Onbyeong can be summarized as follows. First, bleeding in the Yang and Bowel collaterals, then stagnation in the Yang and Bowel collaterals, and finally stagnation in the viscera collaterals or Liver itself. The refractory nature of blood stagnation symptoms of the collateral vessels is mainly due to the characteristics of the collateral vessel itself. In structure, they are very narrow and small, situated at the most terminal part of the body where it is difficult for the Jeong Gi(精氣) to reach. Also, as they are symptomatic of degeneration of Jeong Gi, the root of the disease is very deep. Therefore to resolve blood stagnation in the cases of Ju-Gaek-Gyo and Dry Blood, general approaches using 'Gi communication(行氣)' or 'Blood vitalizing(活血)' medicinals will not suffice. Special medicinals such as crustacean and insects need to be appropriately applied.
