Study on the effect of the water and erhanolicextract of Equisetum arvense L. on some Hematological Parameters in the Albino mice

The present study has been performed on the vegetative parts of the local Horsetail Equisetum arvense L., which grow naturally in Haj Umran in the north of Iraq, to assess the effect of crude extracts of this plant on some hematological parameters in vivo. The results revealed that the crude extracts (water and ethanolic), significantly, increase the lymphocyte level in vivo especially in concentration(50 mg/ml), the results also showed that the crude extracts (water and ethanolic) of (10, 50 mg/ml), significantly, increase the red blood corpuscles count in vivo, while higher concentration (100 mg/ml)has areverse effect(decrease the count), while the crude extracts (water and ethanolic)of (10 ,50 mg/ml), significantly, increase the amount of hemoglobin in vivo, where as higher concentration of(100mg/ml) decrease it. Finally, the low concentration of crude extracts(water and ethanolic) were efficient to increase platelet count in vivo, However, higher concentration of (100 mg/ml)decrease it.
