The S.alata treated rats exhibited significant improvement in most of the hematological parameters and red blood cells indices compared to carcinogen exposed rats (Table ). The data showed that the carcinogen caused a significant decrease in RBC, Hgb, PCV, and PLT counts as compared to control group, and a significant increase in WBC. The hematological parameters in rats treated with 300mg/kg of plant extract, the rats treated with standard cancer drug (Tamoxifen) and control group were similar.
