Many reasons can cause anemia, decreased RBC production or increased destruction of circulation RBC. The investigators investigate the Danggui Buxue Tang (PHY606) composed of Angelicae Sinensis Radix and Astragali Radix in the fields of genomic and metabolomics in the healthy people and the patiens with anemia.

Many reasons can cause anemia, decreased RBC production or increased destruction of circulating RBC. The reasons of the former are lake of nutrients, bone marrow disorder, low level tropic hormone, inflammation associated with infectious, inflammatory, or malignant disorders and the latter are intravascular hemolysis or blood loss. Anemia is characterized by the sign of pallor (reduced oxyhemoglobin in skin or mucous membranes), fatigue, lightheadedness, and weakness associated with low hemoglobin.

Iron deficiency anemia (IDA) is mainly resulted from inadequate iron uptake of food, malabsorption of iron and blood loss. Adult female are easy to have IDA compared to male because of menstruation, pregnancy, lactation and low caloric uptake leading to iron deficiency. In Taiwan, cancer-related and chronic kidney disease also lead to insufficient secretion of erythropoietin (EPO). The cost of long-term use EPO and its derivative drugs is high. Besides, drug resistance, risk of tumor growth and cardiovascular disease are all important issues. However, ferrotherapy will induce GI upset, muscle pain and skin hives. Also, iron supplementation can lead to an increase in infectious disease morbidity in areas where bacterial infections or where malaria are common.

Based on the concept of dietetic invigoration, the investigators investigate the Danggui Buxue Tang (PHY606) composed of Angelicae Sinensis Radix and Astragali Radix in the fields of genomics and metabolomics in the healthy people and the patients with anemia. In the meantime, the investigators will explore whether PHY606 activates the immune function, improves anemia and reduces the side effects induced by anemia treatment. Furthermore, the novel metabolites from Angelicae Sinensis Radix and Astragali Radix will be tested from clinic back to the bench including immunological potentiation and hematopoietic function. According to the TCM theory, the investigators integrate with modern medicine and molecular biotechnology to investigate anemia and hope to provide the evidence base for clinical application.
