A double-blind controlled therapeutic trial of glycyrrhizinic-acid-reduced liquorice 760 mg thrice daily for six weeks was carried out on 90 men with relapse of chronic duodenal ulcer. Effects of treatment were judged by the frequency and severity of pain, the amount of alkali consumed, and the doctors' and patients' rating of the clinical response. The results do not show any advantage for the active treatment when compared with the placebo.
