Study of mice : A study was done to assess the gastroprotective effects of an aqueous suspension of the ethanolic extract from leaves and flowers of Guazuma ulmifolia in a model of acute gastric ulcer induced by diclofenac as ulcerogenic agent, using the proton pump inhibitor omeprazole as a protection reference. It was concluded that the aerial parts of Guazuma ulmifolia protect gastric mucosa against the injurious effect of NSAIDs mainly by anti-inflammatory and radical-scavenging mechanisms .
