Evaluation of sub-acute toxicity profile of Combretum dolichopetalum (E&L) methanol leaf extract in Wistar rats

This study evaluated the safety of the ethnomedicinal plant, Combretum. dolichopetalum methanol extract (CDME) in Wistar rats using the sub-acute toxicity model. Twenty-four adult male Wistar rats were randomly divided into 4 groups of 6 rats each. Group A (control) received 5% dimethylsulfoxide (DMSO) at 5 ml/kg, while groups B -D received CDME at 50, 100 and 200 mg/kg, respectively. All treatments were administered orally and once daily for 28 consecutive days. The haematological profile, liver and kidney function tests, lipid profile as well as antioxidant status were evaluated. The 50 mg/kg extract significantly (P0.05) in leucocyte profile between the control and groups given the extract. At 200 mg/kg, CDME significantly (P
