In this study, we researched the effects of herbal medicine on anemia among 43 patients. Before being given prescriptions, these patients were examined for RBC count, hemoglobin, and hematocrits, which are important in evaluating improvements in anemia. After administering the herbal medicine over two weeks, we rechecked the RBC count, hemoglobin, and hematocrits on a secondary inspection. We compared the primary and secondary tests with respect to age, sex, diseases, the name of the herbal medicine, and the composition of the medicine. The results were as follows. In groups of five or more, the musculoskeletal pain disease group was more improved than the other disease groups on the secondary test. The digestive diseases group was worse than the other disease groups on the secondary test. In the composition of the prescription, herbs that enriched the blood (補血), invigorated the spleen (健脾), and nourished Eum (補陰) were used more than any other herbs for those whose status improved. Among patients who were partially normalized for the secondary test, this applied to men more than women, to patients in the pain group more than those in other disease groups, and to patients with cerebral hemorrhage more than stroke patients. Among patients who were partially normalized for the secondary test, the group taking tangyak herbal medication improved more than the other groups taking powder and pill herbal medications.
