Bile juice prevents deposition of cholesterol in the blood vessel, digests fat, and absorbs fatty acid and vitamins, and it plays a great role on metabolism. Recently, emotional stimulus and mentally over-depression cause a person to come to illness, and westernization of way of life makes more patients with cholelithiasis, resulting into without bile secretion after cholelithotomy. Ageing, and gastrectomy and kidney transplantation are also the causes of more cholelithiasis occurrences. To solve these medical problems, we studied how Fel Sus Scrofa, which is not different from human bile juice, was used in the traditional Korean medicine. We I researched flavor, property, efficacy of Fel Sus Scrofa and how it was used by folk medicine, and we studied the usage examples of Fel Sus Scrofa in Sanghanlon and Dongeuibogam. The property of Sus Scrofa is bitter and cold. Its efficacy is to deposit glycogen. So it is known that it has been widely used, with many edible forms, without any humoral loss, for the inflammatory disease from various fever, problems of urine and feces, cutaneous disease, pulmonary disease, opthalmopathy, fever, thirst from diabetes, hepatocystic duct disorder. Fel Sus Scrofa can be used internally and externally to prevent humoral loss, and to control cutaneous disease among various pediatric disorder full of fever. And as we have in mind that it also can be used to treat patients with cholestasis after cholecystectomy, it is expected that post study of it must be done.
