Beneficial effect of Mentha spicata essential oil on lead and manganese induced nephrotoxicity and oxidative damage in rat kidney

Our work focused on the impact of chronic lead acetate and manganese chloride poisoning on renal function in Wistar rats. It also tested the efficacy of the essential oil extracted from (Mentha spicata) spearmint in reversing these effects by treating previously poisoned rats with a daily intraperitoneal injection of 0.1 ml HEM/kg over a 21-days period. Analysis of this essential oil through gas chromatography coupled with mass spectrometry revealed that the main components are: carvone (42.2%), menthone (20.89%), piperitenone (17.41%) and isomenthone (7.99%). Chronic oral co-exposure to lead and manganese during periods of gestation and lactation resulted in a significant reduction (P
