When granulocytopenia is present, it is important to look for the cause of the granulocytopenia. If it is caused by taking medications, such as methimazole or propylthiouracil, which cause granulocyte reduction, stop the medication if possible. Also, take medications that increase granulocyte production, such as vitamin B4, reserpine, shark liver alcohol, and diethylstilbestrol tablets, which can promote granulocyte production. You can also seek the help of Chinese medicine practitioners to take the pulse and look at the tongue, and restore the hematopoietic function by strengthening the spleen and tonifying the kidneys to produce more granulocytes. Commonly used drugs include Astragalus, Angelica, Ginseng, Atractylodes, Poria, Eucommia, and Sambucus, which can nourish the blood, invigorate the blood, and improve the hematopoietic function of the bone marrow.
