A randomized, double blind placebo controlled study was conducted to evaluate the efficacy of GutGard (root extract of Glycyrrhiza glabra) in the management of Helicobacter pylori (H. pylori) gastric load. Participants diagnosed with H. pylori infection were randomly assigned to two groups to orally receive 150 mg of GutGard ( ) or placebo ( ) once daily for 60 days. H. pylori infection was assessed using 13C-urea breath test (13C-UBT) at days 0, 30, and 60. Stool Antigen test (HpSA) was also performed on days 0, 30, and 60. Repeated measures of analysis of variance (RMANOVA), chi-square, and Fisher's exact probability tests were used to compare the treatment outcomes. A significant interaction effect between group and time ( ) and significant difference in mean Delta Over Baseline (DOB) values between GutGard ( ) and placebo ( ) treated groups after intervention period were observed. On day 60, the results of HpSA test were negative in 28 subjects (56%) in GutGard treated group whereas in placebo treated group only 2 subjects (4%) showed negative response; the difference between the groups was statistically significant. On day 60, the results of 13C-UBT were negative in 24 (48%) in GutGard treated group and the difference between the groups was statistically significant. The findings suggest GutGard is effective in the management of H. pylori.
