A passage from Medicinal Plants of the American Southwest:
Several ounces of pulp mixed with a small amount of water has a cooling effect on esophageal and stomach irritations, be they from acid reflux or gastritis. This antiinflammatory effect soothes irritated gastric membranes. Not only does Prickly pear mucilage serve as a protectant to damaged stomach lining, it also has the ability of augmenting the quality of gastric mucus making it useful as a stomach ulcer healer.
