Background: Azadirachta indica A. juss (AI; Family: Meliaceae) is one of the most useful medicinal plants containing different alkaloids that includes nimbitin, azadirachtin and salanin whose individual effects contribute to the general medicinal properties of the plant. In Nigeria, pregnant and lactating women have been observed consuming aqueous extract of AI and anecdotal reports from them suggest that they consume the extract because of the folkloric belief that it is potentially harmless, it is hematopoietic and protects them from malaria. Aim: This study was designed to investigate the effects of consumption of AI during pregnancy and lactation on some hematological parameters and blood glucose level. Materials and Methods: Sixty female rats weighing 150-200 g were used for this study. The rats were divided into three groups (non pregnant, pregnant and lactating groups) of 20 rats each. Each group was subdivided into four subgroups based on the dose of AI administered. Subgroup I served as control and received distilled water throughout the experiment while subgroups II-IV received 200 mg/kg, 400 mg/kg and 600 mg/kg body weight of the extract respectively for 21 days. On day 20 of extract administration, blood samples were withdrawn from each rat in each group after an overnight fast for the estimation of some hematological parameters and blood glucose level. Results: There were significant increases (P < 0.05 for each) in the packed cell volume (PCV), hemoglobin concentration (Hb), red blood cell (RBC), white blood cell (WBC), and platelet (PLT) and a significant dose-dependent decrease (P < 0.05) in blood glucose level in all groups. Conclusion: It is concluded that the results of the present study seem to justify the folkloric use of AI as a hematopoietic agent with the potential of ameliorating the burden of anemia and hyperglycemia in women especially during pregnancy.
