They were divided into four groups of five animals each. Group A served as the control and received only distilled water. The experimental groups B, C and D. received oral doses of 250mg/kg, 500mg/kg and 750 mg/kg of guava leaf extract respectively for fourteen days. The animals were sacrificed using, chloroform vapor inhalation method and dissected. Liver tissues were removed, weighed, trimmed down and fixed in 10% formal saline for histological studies.
