Background: Human and animal population exposure to arsenic through the consumption of arsenic contaminated water is rampant in many parts of the world. Protective agents of medicinal plants origin could provide maximum protection against toxicities of various kinds. Objective: The protective role of orally administered methanol extract of the leaves of Adansonia digitata (MELAD) on sodium arsenite (SA) - induced clastogenicity and hepatotoxicity in male Wistar rats was evaluated. Materials and Methods: Thirty male Wistar rats divided into six Groups (1–6) of five animals each were used for the study. Group 1 (negative control) received distilled water and normal diet only, Groups 2–6 received the extract (at 250 or 500 mg/kg body weight) and/or SA at 2.5 mg/kg body weight. Results: There was statistically significant (P < 0.05) increase in the number of micronucleated polychromatic erythrocytes and lipid peroxidation in the SA group as compared with the negative control and treated groups. Administration of the extract reduced the effects of SA on the above parameters. Activities of serum alanine and aspartate aminotransferases did not show statistically significant effects; however, the histological analyses revealed periportal cellular infiltration by mononuclear cells, whereas the MELAD treated groups show mild cellular infiltration and mild portal congestion. Conclusions: MELAD protect against SA-induced toxicities in rats, and it may offer protection in circumstances of co-exposure and cases of arsenicosis.
