The major ingredients within Astragali Radix, that is, formononetin, ononin, calycosin, and calycosin‐7‐O‐β‐d‐glucoside, have been employed to enhance hematopoietic functions by regulating erythropoietin (EPO) expression; hence, possibly could be used in treating anemia 18, 19, 20. This evidence concerns the gene EPO and anemia (phenotype).
