The extract at 100 mg/kg produced a significant (p < 0.05) dose dependent healing effect (81.35% inhibition) at a mean ulcer index of 5.5 ± 0. 93 and a significant (p < 0.05) mean ulcer index from 29.5 ± 0.39 and 21 ± 0.85 to 2.0 ± 1.15 in group V (93.22%) at 200 mg/kg. The results suggested that the methanolic extract of Musa paradisiaca possess both ulcer prevention and healing effect. This effect was however decreased when the extract is administered with catecholamines.
