Thirty adult Wistar rats were used for this study. The Wister rats were divided into three groups; group A was the control animals and tagged C, group B animals received 10g of alum dissolved in 1000cm3 of distilled water and were tagged T1, group C animals received 50g of alum dissolved in 1000cm3of distilled water and were tagged T2, via drinking water for duration of four weeks. Twenty-four hours after the last administration, the rats were sacrificed by cervical dislocation. The adrenal gland was excised and preserved in 10 % formosaline after which it was routinely processed for hematoxylin and eosin staining (H&E). Histological observations showed normal cell distribution in the control group but treated group revealed evidences of cellular obliteration& hemorrhagic necrosis. The results obtained from this study suggest that aluminum sulphate has a damaging effect on the structure of the adrenal gland. Keywords: Adrenal gland; Aluminum sulphate; Histology
