A double-blind trial of deglycyrrhizinated liquorice was performed in 47 patients with active duodenal ulcer. Twenty-four patients received a placebo and 23 the trial medication (Caved-S) for one month. Both groups were clinically similar. No advantage of deglycyrrhizinated liquorice over placebo was found.
