We report the case of a 76-year-old woman diagnosed with refractory anemia arising from myelodysplastic syndrome. Vitamin K 2 was administered, but pancytopenia continued to progress. At the initial visit to our department, her white blood cell count was 2150/μL, hemoglobin (Hb) was 9.6 g/dL and platelet count was 2.3×104/μL. Juzentaihoto was administered for Qi and blood deficiency. A dosage of shimotsuto was increased from 3 to 5 g, and juzentaihoto was changed to ogikenchuto go shimotsuto, but the anemia did not improve. Juzentaihoto was again administered, and the dosage of shimotsuto was increased to 6 g. Malt sugar, 10 g, was added to the decoction, after which her Hb and platelet count markedly increased. There was no significant difference between pre- and post-treatment bone marrow findings. It is possible that malt sugar enhances the hematopoietic function of juzentaihoto.
