We experienced two cases of Tsutsugamushi disease which occurred in October, 2000. The patients, who were over 70 years old and living in a rural area, visited Wonkwang University Oriental Chonju Medicine Hospital because of suffering fever, chill, skin rash, abdominal discomfort, and general weakness for a duration of seven days. The diagnosis was confmned as Tsutsugamushi disease by clinical findings such as eschar and high antibody titers on Reverse Passive Hemagglutination(RPHA). As for treatment, we used Sengmagalgentang-gamibang during the acute and Chojungikitang during convalescent phases of the illness. The patients were treated with Doxycycline of western medicine. The patients improved within 3 days of admission and were discharged within one week.
