A study on haematological effects of aqueous extracts from Phyllantus amarusand Xylopia aethiopica was investigated in albino rats. The extracts from both plants caused a dose-dependent decrease in erythrocyte sedimentation rate (ESR) with 400mg/kg of X. aethiopicacausing the least ESR of 2.7±0.6mm/hr. Significant increases were obtained in red blood cell (RBC) count especially with 100mg/kg of P. amarusand X. aethiopicathat caused 5.6% and 7.8% increases in RBC count respectively (P< 0.05). Similar pattern of result was obtained for packed cell volume (PCV). P. amarusdid not appear to affect haemoglobin concentration, but higher values of HB concentration were obtained for X. aethiopica; the difference was, however, not significantly different from the control (P>0.05).Total and differential count studies showed significant increases in the number of circulating leucocytes and neutrophils respectively especially with 100mg/kg of extracts (P<0.05). Assessment of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) gave significantly higher values of ALT for P. amarus – treated rats (P < 0.05). It was therefore suggested that while both plants can serve as immune boosters and blood tonics, there is need for caution on excessive and prolonged consumption of P. amarus.
