Abstract

Natural products have long been used as therapeutic agents; however, many lack comprehensive scientific evaluation of their toxicity. This study investigates the potential toxicity of Phyllanthus niruri (P. niruri) aqueous leaf extract in Wistar rats. Twenty-five male albino rats were randomly divided into five groups of five animals each. Groups 2 through 5 received daily oral doses of 100, 200, 400, and 800 mg/kg body weight of the extract, respectively, while Group 1 served as the control and received only grower mash and distilled water for 28 days. Toxicological assessment was conducted through hematological profiling and evaluation of liver and kidney function using standard biochemical methods. The results indicated a significant, dose-dependent increase (p<0.05) in the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP), suggesting hepatic stress. In contrast, albumin, creatinine, and urea levels did not differ significantly (p<0.05) from the control group, indicating no observable impairment in renal function. Hematological analysis revealed a significant decrease (p<0.05) in packed cell volume (PCV) and red blood cell (RBC) count, while white blood cell (WBC) count, hemoglobin (Hb) concentration, and mean corpuscular volume (MCV) significantly increased with higher extract doses. These findings suggest that while P. niruri is traditionally regarded as a natural remedy, its aqueous leaf extract may induce hematological and hepatic alterations at elevated doses. Caution is therefore advised in its use, particularly in unregulated or prolonged applications.

Abstract

Herbal remedies have been used since ancient times, often sourced from local traditional healers. However, many of these preparations are administered without thorough scientific evaluation. This study aimed to assess the effects of aqueous leaf extract of Detarium microcarpum on liver and kidney function in Wistar rats. A total of 25 male rats were randomly assigned to five groups of five animals each. Groups 2, 3, 4, and 5 received oral doses of 200, 400, 600, and 800 mg/kg body weight of the extract, respectively, for 21 consecutive days. Group 1, serving as the control, received only normal saline. Liver function was evaluated by measuring serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), total protein, and albumin. All liver parameters exhibited a significant dose-dependent increase (p<0.05) in the treatment groups compared to the control, indicating hepatotoxic effects. Similarly, kidney function parameters, including bicarbonate (HCO₃⁻), chloride (Cl⁻), sodium (Na⁺), and potassium (K⁺), also showed a significant dose-dependent increase. Conversely, levels of urea and creatinine significantly decreased (p<0.05) in the extract-treated groups relative to the control. The findings suggest that the aqueous leaf extract of D. microcarpum adversely affects liver and kidney function in a dose-dependent manner. Therefore, despite its traditional use, the extract should be considered potentially toxic and used with caution.
