(Deglycyrrhizinated Licorice) DGL for ulcershas been studied and found to be clinically effective.
In this study, 100 patients with benign gastric ulceration were treated in a single-blind, endoscopically controlled trial to assess the relative efficacy of cimetidine and a product with DGL as its main ingredient (Caved-S).
Ulcer healing was assessed after six weeks’ treatment, and, if incomplete, after a further six weeks. Both treatments had a 63% ulcer heal rate at six weeks and 91% at 12 weeks.
After ulcer healing, drug dosage was reduced. So far, 56 patients, 28 in each group, have completed the first year’s maintenance treatment, and there have been four ulcerrecurrences in each group (14%).
