Hepatocurative effect of aqueous extract of Hibiscus sabdariffa on some antioxidants and haematological indices of acetaminophen-challenged Wistar albino rats

Hibiscus sabdariffa is among the medicinal plants which have been shown to possess several medicinal properties. The present study was conducted to investigate the antioxidant and haematological properties of the aqueous leaf extract of H. sabdariffa on acetaminophen-challenged liver using rat model. Twenty (20) Wistar albino rats were used for this study and were divided into 4 groups of 5 rats each. Group 1 rats were the normal control; group 2 (positive control) rats were administered acetaminophen only, at a dose of 750 mg/kg b.w. ip. Group 3 rats were administered mid dose (400 mg/kg b.w) of the extract after acetaminophen-induction while group 4 rats received high dose (600 mg/kg b.w) of the extract after acetaminophen-induction. Group 2 rats showed a significant (p
