Background and Aim: Since prior to any research on the drugs, it should be aware of its allergic dose, and considering the importance of hematological system, which reveals the changes in the body, in this study, we decided to investigate the hematologic effects of sumac plant and compare it with a chemical agent (levamisole). Therefore, in future studies, it will be used with ...
