Objective. Functional dyspepsia (FD) is a frequent clinical finding in western world. The aim of this study is to compare the efficacy of a ginger and artichoke supplementation versus placebo in the treatment of FD. Methods. A prospective multicentre, double blind, randomized, placebo controlled, parallel-group comparison of the supplement and placebo over a period of 4 weeks was performed. Two capsules/day were supplied (before lunch and dinner) to 126 FD patients (supplementation/placebo: 65/61). Results. After 14 days of treatment, only supplementation group (SG) showed a significant amelioration (SG: MCA score units (u), ; placebo:  u, ). The intercept () resulted to be significantly higher in SG than in placebo ( u, ). At the end of the study, the advantage of SG versus placebo persists without variation ( u, ). In SG, a significant advantage is observed for nausea ( u, ), epigastric fullness (, ), epigastric pain ( u, ), and bloating ( u, ). Conclusions. The association between ginger and artichoke leaf extracts appears safe and efficacious in the treatment of FD and could represent a promising treatment for this disease.
