Effect of an ashwagandha ( Withania Somnifera ) root extract on climacteric symptoms in women during perimenopause: A randomized, double‐blind , placebo‐controlled study

A randomized, double blind placebo controlled study was conducted to evaluate the efficacy of GutGard (root extract ofGlycyrrhiza glabra) in the management ofHelicobacter pylori(H. pylori) gastric load. Participants diagnosed withH. pyloriinfection were randomly assigned to two groups to orally receive 150 mg of GutGard (n=55) or placebo (n=52) once daily for 60 days.H. pyloriinfection was assessed using13C-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 (P=0.00) and significant difference in mean Delta Over Baseline (DOB) values between GutGard (n=50) and placebo (n=50) 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 of13C-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 ofH. pylori.

Background: Anxiety disorders are the most universal psychiatric problems in the general population. Due to their chronic nature, these diseases are managed with a multi-drug regimen lasting for a long period of time. Medication discontinuation leads to 25% and 80% recurrence in the first month and the first year, respectively. Despite several treatment approaches, there is no specific and optimal method for patient management. Therefore, it is necessary to find some new theraputic approaches with fewer side effects. Withania somnifera is a plant with GABAergic property responsible for its anxiolytic effect. The aim of this study was to investigate the effect of W. somnifera root extract as an alternative therapy to reduce standard generalized anxiety disorder (GAD) symptoms. Methods: Forty patients who met the inclusion criteria (with a confirmed diagnosis of GAD as stated in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) took part in this randomized double-blind placebo-controlled trial and were randomly selected for participation in the treatment group (W. somnifera extract, 1g/day; n = 22) or the placebo group (n = 18). All patients were under treatment with Selective Serotonin Reuptake Inhibitors (SSRIs) and were prescribed one capsule of the extract or placebo per day for six weeks. The Hamilton anxiety rating scale (HAM-A) was used to assess the severity of GAD symptoms at baseline as well as the second and sixth weeks of the trial. Results: Comparison of the HAM-A scores during the course of the trial revealed a significant amelioration ofHAM-A score in the treatment group versus placebo (14 and 8 units reduction, respectively (P < 0.05)). Moreover, there was a significant difference in the reduction of GAD score between the second (P =0.04) and sixth week (P =0.02) in the treatment group. The extract was safe and no adverse effect was observed during the trial. Conclusion: W. somnifera extract offers some potential advantages as a safe and effective adjunctive therapy to SSRIs in GAD.
