(a) Effect of polyphenol-rich extract of the leaves of Vernonia amygdalina (PEVA) on the urine volume of rats with Cd-induced toxicity. (b) Differences in the urine volume (ml) of control and PEVA-treated groups, during weeks 1 and 4 post-Cd toxicity with reference to baseline values. Each value represents mean ± standard error of mean (n = 5); *significantly different from Control Group (P < 0.05); ^#significantly different from Cd group; ^§significantly different from Cd + recovery group (P < 0.05); µ: significantly different from Cd + 400 mg PEVA group (P < 0.05)
