1. Objective The object of this study was to understand the clinical characteristics of the Taeeumin Symptomatic Pattem. 2. Methods The patients visiting the department of Sasang Constitution of Traditional Korean Medicine clinic from June to November of 2008 were used in this study. Those who showed a favorable turn after over ten days of medication and who showed up for at least two follow-up sessions were chosen among first-time visitors. Of these, 75 patients identified and verified to be of the TE type were chosen for the study sample. The Taeeumin were verified into two groups according to clinical symptoms into Exterior Cold Disease and Interior Heat Disease groups, of which the Interior Heat Disease group was further subdivided into the Galgeun-medicament group and the Cheongshimyeonja-tang group, based on questionnaire results. The Exterior Cold Disease group was set as the control group in order to contrast and compare it with the study group, the Interior Heat Disease group. 3. Results and Conclusions The questionnaire items shown to differentiate the Exterior Cold Symptomatic Patterm and the Interior Heat Symptomaic Pattern (indicating Heat-affceted Liver Symptomatic Pattern) were related to "dryness of stool," "dark urine colorm," "dryness of nose," and "dryness of lips." The items shown to differentiate the Galgeun-medicament group and the Cheongshimyeonja-tang group (of the Dry - Heat Symptomatic Pattern) were related to "nausea," "stifling sensations and palptation," "disturbed sleep," and "dizziness." Therefore, the sleep pattern, palpitation, dizziness, and nausea can be said to be indicators of the Interior Heat Symptomatic Pattern, and Dry-Heat symptoms are better distinctions between the Chongshimyeonja-tang group and the Galgeun-medicament group than Heat-affected Liver symptoms.
