Lead toxicity and related health issues have become global concern due to increased use of lead-based products in the modern world. Though attempts are being made to tackle this malady through many ways, the use of naturally occurring materials that are available locally is a subtle approach. In this investigation, the fruits of E. officinalis (EO) were studied for their potential in overcoming biochemical and hematological alterations caused by metallic lead in rat model. Four groups of rats, each containing six animals, were considered for the study. Group I served as normal control while to other groups (II– IV), metallic lead powder (100 ppm/rat) was orally administrated for 30 consecutive days. From day 31, the animals in groups III and IV were treated with EO in doses of 50 and 100 mg/kg body weight (p. o.), respectively, for the following seven days. Group II served as lead-treated control. On day 38, the animals in all groups were sacrificed and the blood was collected and serum separated. The changes in biochemical (aspartate aminotrasferase, alanine aminotrasferase, alkaline phosphatase, gamma glutamyltrasferase, total cholesterol, triglycerides, urea, creatinine and calcium) and hematological (red blood cell count, white blood cell count, hemoglobin, packed cell volume and platelet count) parameters were estimated. Lead treated animals in Group - II showed appreciable changes in hematological and biochemical parameters. Treatment with EO (50 and 100 mg/kg) significantly restored the changes in the above parameters to near normal values implying that the fruit of E. officinalis is an effective natural material to overcome widespread lead toxicity. This observation is further supported by histopathological studies of liver and kidney tissues wherein the distorted architecture, degeneration and other changes found in lead-treated animals were brought back to near normal stages by the treatment of EO.
