A 63-year-old female diagnosed with Ramsay Hunt syndrome with multiple cranial nerve palsy, presenting with severe dizziness and nausea, was treated using Korean medicine, including herbal medicine (<i>Geopung-tang</i> and <i>Gyejibanhasaenggang-tang</i>), acupuncture, pharmacopuncture, electroacupuncture, and moxibustion. The patient underwent a 58-day course of treatment during hospitalization, and the effects were evaluated using the Korean dizziness handicap inventory, the index of nausea, vomiting, and retching, the gastrointestinal symptom rating scale, and the numeric rating scale for dizziness and nausea. Vestibular function was assessed using the video head impulse test. After treatment, the patient showed significant improvement in dizziness, nausea, and her overall health condition. This case suggests that Korean medicine may offer an effective treatment for persistent dizziness and nausea in patients with Ramsay Hunt syndrome, particularly when conventional treatments are insufficient.
