dc.description.abstractHematological disorders have attained epidemic proportions worldwide today. As a result, many people turn to medicinal plants for treatment thereby boosting and enhancing health because professional care is not immediately available, is too inconvenient, costly and time consuming. Certain medicinal plants are believed to promote positive health and maintain organic resistance against infection. The use of medicinal plants which are readily available and arguably efficacious would therefore over a better and affordable alternative for boosting and enhancing health. Assessment of hematological parameters can be used to determine the extent of deleterious effect of foreign compounds including plant extracts on the blood constituents of an animal. Various chemical constituents of Vernonia lasiopus are believed to possess therapeutic effects on hematological parameters. However, these effects have not been subjected to systematic studies to substantiate the therapeutic claims made regarding their clinical utility. This study was designed to investigate the hematological effects of V. lasiopus (O. Hoffman) in normal mice. The experimental groups were treated with leaf extracts at concentration of 50 mg/kg and 100 mg/kg orally once per two days for a period of fourteen days. Hematological parameters and indices were determined from unclotted blood samples using standard protocols. Presence of various types of phytochemicals was assessed using standard procedures. The leaf extract of V. lasiopus (O. Hoffman) induced changes in erythrocytes and related parameter profiles, total and differential WBC counts, platelets and their related parameters in normal mice at the two tested dose levels of 50 mg/kgbw and 100 mg/kgbw. Further, the phytochemical screening results showed that the leaf extract of V. lasiopus (O. Hoffman) have phytochemicals associated with erythropoietin promoting activity, immunostimulatory activities and thrombopoietin stimulation.en_US
