To describe the effects of traditional Korean medicine (TKM) on a patient diagnosed with Parkinson's disease. Methods: The patient was treated with Korean medicine, including pharmacopuncture, acupuncture, and Chungpajunsin-bang. The Unified Parkinson's Disease Rating Scale (UPDRS) and modified Hoehn and Yahr staging (H-Y stage) were used to measure changes in amplitude and improvements in the patient's symptoms. Results: After treatment with the Korean medicine, according to the UPDRS and H-Y stage assessments, the patient's tremor improved, with the tremor amplitude decreasing from 30 cm to 5 cm. Conclusions: We suggest that TKM could be effective in reducing tremor in Parkinson's disease.
