The present study assessed the antiulcer activity of the plant, as well as explored the possible mechanisms of action of the herbal drug, aside identifying some of the various phytoconstituents, which could be responsible for its antiulcer activity. Different ulcerogens (ethanol 99.9 %, indomethacin 50 mg/kg, cysteamine 400 mg/kg, glacial acetic acid) and the pylorus ligation-induced ulcers were used to induce acute and chronic ulcers, with doses of 100, 300 and 750 mg/kg DAG and the standard drugs relative to each model, while assessing drug activity through ulcer scoring and comparing it with both the negative and positive controls. The extract, which has an LD50 of 1584.89 mg/kg when administered intraperitoneally, recorded a significant (p
