Objectives We report a series of 3 chronic tension-type headache cases who were constitutionally typed as the Soeum type, Taeeum type and treated with Dangguibaekhaoguanjung-tang, Chungshimyeonja-tang or Chunghyulganggui-tang. Methods In treating 1 patient who was constitutionally typed as the Soeum type, Case 1 fell into the category of the Taeeum symptomatology, 2 patients who were constitutionally typed as the Taeeum type, Case 2 and Case 3 fell into the category of Dry-Heat symptomatology. Each patient was given Sasang medication according to protocol: Dangguibaekhaoguanjung-tang to Case 1, Chungshimyeonja-tang to Case 2, Chunghyulganggui-tang to Case 3. On admission day and approximately 2 weeks later, patients evaluated their pain and quality of life using SF-36 and HIT-6. The patients symptoms were observed daily and NRS scores were recorded daily. Results and Conclusions 2 Patients(Case1, Case2) showed improvement in their NRS scores, SF-36 scores and HIT-6 scores. 1 patient(Case3) showed improvement in NRS scores, but worse SF-36 scores and no improvement in HIT-6 scores. Treating chronic tension-type headache based on Sasang Constitutional therapy was found to be effective for managing pain. The treatment protocol suggested in this investigation should be explored and verified in future studies.
