ASSESSING THE BIOCHEMICAL EFFECTS OF PHYLLANTUS AMARUS AND BITTER LEAF ON THE LIVER AND KIDNEY USING ADULT WISTAR RAT.
Abstract
Phyllanthus amarus and Bitter Leaf are widely known for their medicinal benefits, particularly in
liver and kidney health. However, their effects on biochemical parameters in animal models
require comprehensive study. This research investigates the effects of Phyllanthus amarus (Extract
X) and Bitter Leaf (Extract Y) on liver and kidney function parameters in adult Wistar rats.
Twenty-one rats were randomly divided into seven groups (n = 3 per group). Group 1 received 0.5
ml/kg/week of Phyllanthus amarus (X); Group 2 received 1.0 ml/kg/week of Phyllanthus amarus;
Group 3 was administered 0.5 ml/kg/week of Bitter Leaf (Y); Group 4 received 1.0 ml/kg/week of
Bitter Leaf; Group 5 was given a combination of 0.5 ml/kg/week of Phyllanthus amarus and 0.5
ml/kg/week of Bitter Leaf; Group 6 received a combination of 1.0 ml/kg/week of Phyllanthus
amarus and 1.0 ml/kg/week of Bitter Leaf; Group 7, the control, received only standard diets and
water. The extracts were administered orally for 21 days. Biochemical parameters, including urea,
creatinine, alkaline phosphatase (ALP), alanine aminotransferase (ALT), and aspartate
aminotransferase (AST), were measured. The results showed that Phyllanthus amarus
significantly decreased ALT and AST levels at higher doses (1.0 ml/kg), suggesting
hepatoprotection, while a low dose (0.5 ml/kg) increased creatinine levels, indicating possible
renal stress. Bitter Leaf increased ALT, AST, and ALP levels at higher doses (1.0 ml/kg), reflecting
potential hepatotoxicity. Significant differences were observed in ALT, AST, and creatinine levels
between treated groups and the control (p < 0.05), especially in groups receiving Bitter Leaf. The
combination of both extracts produced mixed results, with a high-dose combination showing an
elevated risk to both liver and kidney functions. Phyllanthus amarus may offer hepatoprotective
benefits, whereas Bitter Leaf poses hepatotoxic risks at higher doses. Both plants also influence
kidney function, suggesting the need for cautious use. Further studies are required to explore their
clinical relevance and establish safe dosages for medicinal use.
