An oropharyngeal cancer patient often suffers from dysphagia either due to their disease or as a consequence of their treatment. Here we report a case of a 61-year-old female with the oropharyngeal cancer-related dysphagia, which was effectively treated with Kampo medicine. After four weeks of treatment with hangekobokuto, her swallowing function was improving. Concomitant use of bakumondoto reduced a feeling of xerostomia. She could return to work. The treatment with Kampo medicine might be effective to reduce the cancer-related symptoms and to improve the quality of life of the cancer patients.
