There are donkey-hide gelatin, red dates, nut skins, bovine bone marrow and so on. Raise white blood cells, but not as fast as drugs. If the white blood cell count is less than 4,000 and more than 3,000 after chemotherapy, you may be given "Shengbai" oral liquid. If the price is less than 3,000, I will give you a nourishing injection, and you can eat Zi Long Gold, Shengxue Pills and Zaofan Pills in advance.
