Objective: The purpose of this study was to report the clinical course of complex Korean medicine to treat a patient with hemorrhagic transformation following cerebral infarction.Case presentation: A 46-year-old Korean male was hospitalized with cerebral infarction followed by hemorrhagic transformation classified as parenchymal hematoma type 2. Based on the symptoms and condition, the pattern identification of the patient was deficiency of qi and retention of fluid (Qi-xu, Tan-yin). The patient was treated with herbal medicine, acupuncture, and rehabilitation programs for 187 days. The herbal medicine consisted of modified <i>Geopoongjaeseup-tang</i> (modified Qufeng Chushi decoction) for the first 62 days, followed by another modified <i>Geopoongjaeseup-tang</i> for the next 76 days, and finally <i>Gagamyoonjo-tang</i> (Jiajian Runzao decoction) for the last 30 days, administered 3 times a day. After 187 days, the functional independence measure and modified Barthel index improved (from 75 to 100 and from 44 to 84, respectively), and the MMT of the right upper and lower extremities also improved (from 2+ to 3+ and from 3+ to 4, respectively). In particular, right finger flexion improved from 1 to 3- and right ankle and greater toe improved from 1+ to 4. There were no reports of adverse effects of the treatment.Conclusion: The results suggest that complex Korean medicine treatment for motor and language impairments caused by parenchymal hematoma type 2 hemorrhagic transformation may be effective in improving functions for daily living. Further studies should be conducted with a larger number of patients.
