A prospective, open randomized clinical trial study (a 14-day study of 200 patients with peptic ulcers and Helicobacter pylori-positive), group A used proton pump inhibitor triple therapy, group B used the original triple Cranberry capsules are added in addition to the first therapy.

It was found that the Helicobacter pylori eradication rate in group A was 74% and that in group B was 89%, which shows that cranberry capsules can improve the therapeutic effect.
